Announcements & Reminders

  • Terrain removal - As part of the performance optimization effort, we have decided to pull the Terrain system from Sansar.
    • We recommend replacing all existing terrain created using Sansar's terrain system or through uploaded heightmaps before then. After the end of April, all terrain items that are still in scenes will be replaced by a placeholder asset.
    • All terrain items in the Store that have been created using a terrain heightmap should also be removed from the Store as soon as possible.

Known Issues

Resolved known issues from previous releases

  • Accounts that have not finished the account creation process by creating an Avatar ID cannot log in the client.
  • Avatars drift slowly across the scene even without user input.
  • Occasionally, media streams (Youtube only) will not play on media surfaces when testing using the audio/video preview button or while visiting an experience.
  • Spot lights positioned together in large clusters may cast large shadows.
  • At times, uploading the same clothing item to two separate menus can potentially cause a crash. 
  • The most recent message displayed in the Chat app gets partially cropped.
  • The UI might disappear by pressing the Y button (Oculus) / left menu button (Vive) when in VR in the log-in screen, home Atlas and loading screen.
  • Taking a screenshot from the Atlas after selecting a new Sansar Look may crash the Sansar client.
  • Sansar freezes sometimes when script console is opened.
  • Scripting bugs:
    • Fix named ScriptEvent limitations: limit is now only on the number of active subscriptions and is much higher.

    • LightComponent.GetAngularFalloff() returns values that are in a much different scale than the scene editor
    • LightComponent.GetNormalizedColor() returns a different color than what the scene editor shows
    • LightComponent.GetRange() returns a different range than what the scene editor shows
    • createData.ClusterReference.GetObjectPrivate(0) returns null and prevents scripts from reading or setting various properties on objects they spawned. 
    • Script that call Cluster.Destroy() with OperationComplete delegate eventually stalls.
    • Removed limit on number of Command subscriptions from Client.SubscribeToCommand
.
    • When LightComponent.SetColorAndIntensity() is called to enable a light, the light does not render until the client reloads the experience
    • Updating properties of LightComponents attached to objects fails
    • LightComponent.SetColorAndIntensity() allows unbounded magnitude, leading to nonfinite values
    • LightComponent.SetColorAndIntensity() allows negative color and intensity, if all values are negative

Known issues for this release

  •  Audio events triggered by trigger volumes start playing every time the avatar enters or exits the volume, even though the audio file is already playing. This results in multiple overlapping audio playbacks.
  • When using the BACK button in the clothing adjustment mode, a Discard/Save modal appears as the changes are finalized.
  • The pins still stay in place when pressing R to reset in clothing adjustment mode. To remove, press W+Left Mouse button.
  • Moving the right arm on an avatar from behind the head and up and over to the chest area can cause the arm to twist permanently.
  • Most of the UI buttons in the lookbook is unresponsive when viewing it from a narrow client window.
  • In VR, the female avatar's left hand twitces against the hip while performing the idle animation.
  • Parenting an object to a bone rig will cause failures upon import into Sansar.
  • Assets that have been rigged with groups nested under groups will appear mangled and broken in an experience.
  • When importing objects, an object without a collision mesh's Motion Type cannot be set to keyframed or dynamic and can only be set to static. Currently, the import panel doesn't make it clear that the dropdown is disabled without a collision mesh.
  • The input boxes in the Diagnostics toolbar cannot be typed in.
  • Shift + click to select multiple objects does not work when the properties panel is open. Make sure that the properties panel is closed when selecting multiple objects.
  • Audio/media streams that are assigned in the scene settings panel in one scene may appear in the audio emitter stream drop down menu in other scenes.
  • When laid flat against a flat object plane, thin object bodies fall through the flat plane.
  • Throwing objects against other avatars may cause them to move back slightly.
  • The avatar info tool remain active on screen even when you are no longer hovering an avatar.
  • Occasionally, when visiting experiences in VR and switching into 1st person camera mode, the avatar may render incorrectly and obstruct view.
  • Avatars can be moved around while in free cam mode.
  • When viewed from a far camera angle, a group of multiple point lights may begin turning on and off, making some lights look dark.
  • Some textures may reflect black patches when it contains colors out of the normal range.
  • Some dynamic assets are not culled properly in experiences.
  • Script functions to set RigidBody position, orientation, and velocity on static objects are reported as a success, despite failing to move static objects. As a note, static objects cannot be moved by scripts.
  • RigidBody.SetOrientation(Sansar.Vector) should be a deprecated method. However, scripts with the function can still be uploaded in Sansar and errors out. Moving forward, it is best to use the RigidBody.SetOrientation(Sansar.Quaternion) method instead. 

Known issues from previous releases

  •  General
    • The Chat app appears on screen slightly off screen in certain screen resolutions, hiding the text input field. You must manually move the chat app in the screen to reveal the text input field.
    • The screen will flicker violently in desktop mode when wearing the headset while existing the lookbook app. This does not affect what is visible in the HMD lenses.
    • The client stalls and takes a while to transition into the loading screen after clicking "Visit Now" from edit mode.
    • The client crashes when a user is kicked out of Sansar by admins.
    • Favoriting/unfavoriting an experience from the web Atlas will break the favoriting/unfavoriting button in the client. As a workaround, we suggest closing the Atlas panel in the client and reload the data.
    • At slow internet connections, the lack of response from the loading bar may look like Sansar is not active.
    • The right arrow on the experience details page in the Atlas only scrolls to the last loaded experience on the Atlas and fails to scroll through all experiences on the Atlas.
    • Attempting to open the Atlas after exiting VR mode in edit mode can cause Sansar to crash.
    • The My Experiences app does not automatically refresh to show the updated image of an experience. To see the changes, close and re-open the My Experiences app.
    • Experience titles that exceed 25 characters get cut off in the experience details page.
    • At times, Avatar IDs display incorrectly and shows a long string of text and numbers. When this happens, try closing and re-opening the People app to see the correct Avatar ID.
    • The People app button no longer highlights when users receive friend requests. However, friend requests still come in successfully.
  • Events app
    • An event listing will disappear from the Events app if the experience associated with it is deleted. In addition, this does not pull the data entirely and the time slot of the missing event will still be "taken", preventing the creation of a new event under the time slot. To fix this issue, you may request for assistance from the support team.
    • The Events app does not refresh data when you switch between tabs. To refresh data, you will have to exit the events app and open it again.
    • There is no reminder that only the event creator can visit an event that will be located in an experience that has access set to "Only Me".
  • Avatars & the avatar app
    • Avatars appear to have slouching shoulders after calibrating height in VR.
    • Avatars do not run at full speed when using the simple controls. This applies to the Oculus touch controllers and the standard gamepad.
    • Avatars have IK issues in the elbows and arms while rotating the Touch controllers or Vive wands.
    • In VR, avatar wrists twist around like "candy wrapping" when turning the hands inward and outward using the touch controls.
    • The male avatar's right thumbnail texture is not properly lined up with the thumb.
    • The avatar head may appear broken when the avatar is looking around in VR mode.
    • The avatar continues to move forward for a few steps even after the controls for running has been let go.
    • Using avatar emotes in an experience causes avatars to stop performing idle animations.
    • Avatars spin and face the opposite direction when activating and deactivating the teleport beam without teleporting.
    • Avatars fall unnaturally in experiences with low gravity.
    • Avatar heads' rotation and tilt no longer have any limitations set. 
    • Male avatars' right hand shakes when the right VR controller is rotated at certain angles.
    • In VR, shoulders will clip through MD clothing as the avatar walks and moves their arms around.
    • If an accessory is deleted from the inventory of a specific avatar, it will still appear on any other avatar's appearance if that avatar is still wearing the accessory at the time of deleting.
    • Occasionally, some avatars get caught on some objects as the objects are pushed away from them.
    • The avatar head can only be moved in a limited range.
    • The 1st person desktop camera may shake when visiting an experience. This is most notable when looking straight down.
    • Switching your avatar between genders may cause the avatar's mouth to not move in accordance with the vocal sounds you create.
    • At times, objects grabbed in VR appear offset and do not track the user's hands.
    • Sansar will occasionally crash if the user goes in and out of the avatar customization app and saves changes to an avatar.
    • It's possible to get your avatar's arms to clip into its torso.
    • Avatars may take a quick step if a controller is used to navigate the avatar slowly through the experience.
    • The female avatar's nose will tear up when the nose slider is set to the maximum value.
    • Male avatars forward left strafe is not smooth while in first person camera mode. The avatar will appear to wobble left and right as they walk.
    • MD clothing items created using the male body shape on female avatars causes the clothing item to conform to the male avatar's body shape, instead of the female one. This causes those clothing items to float above the female avatar, instead of naturally laying on the female avatar's body.
  • Items & the upload tool
    • If temporary files for Sansar are partially deleted, all future imports through the asset importer fails. However, if all contents in the temporary folder are deleted, it doesn't affect future imports of the files.
    • Exporting assets with Y up from Z up native programs does not convert to Z up when entering Sansar.
    • Some objects may fail to upload indefinitely when the import cache is lost or corrupted unless the user deletes the whole import cache.
    • Sansar crash can be caused by deleting a portion of the cache and then upload an asset that relied on that piece of cache that was deleted. Or, caused by uploading the same asset numerous times before the others uploads have finished.
    • PC network drives fail to appear on the file explorer when uploading a file using the upload tool.
    • Animated objects lose their animation when uploaded with a collision mesh.
    • A majority of textures assigned to .obj files do not import into Sansar.
    • Some textures appear posterized after uploading them to Sansar.
    • Multi-part objects cannot currently be paired with a collision volume, which means they cannot be made dynamic or collide with other objects.
  • Edit Mode:
    • The user input value on a Volume RBOD component's scale in the scene objects heirarchy changes in relation to the user input value assigned on the object's top-level scale. The Volume RBOD component's scale becomes auto-computed and multipled times the user input value in the object's top-level scale.
    • When 'surface snap' is enabled in edit mode, grabbing objects while editing in VR becomes difficult.
    • Switching to VR while building a scene makes the 'building' indicator vanish and stay hidden until the build process is completed.
    • Script properties revert back to default values when uploading a script while the properties panel is open.
    • Some dynamic objects will appear to spring back and forth on screen when held by an avatar.
    • Occasionally, dynamic objects do not collide with other objects and may temporarily fall through them for a few seconds, before snapping back to the other objects' surface.
    • Occasionally, some dynamic objects may jump away beyond the expected force from the avatar when colliding with them.
    • When undo (ctrl+undo) is used to remove directional lights in a scene, it causes an error and prevents a user from adding another directional light into the scene.
    • Clearing debug messages from the script debug console will reappear and stack on each other every time the script console is opened.
    • Sansar crashes if an asset with a really high-resolution texture is added to a scene from the inventory.
    • When editing an animated object, the Scale property only affects the object's size and not the distance the object travels during its animation. This means that scaling an animated object can often lead to unexpected and undesirable results, so make sure to model to the appropriate scale in your 3D modeling tool.
    • If an animated object's static mesh component is moved from its original container in the scene objects panel, the object's animation will no longer play.
    • In desktop mode, trigger volumes show the gizmo and the mini-object toolbar, which acts as a visual indication that it is selected. However, in VR mode, the gizmo and the mini-object toolbar are missing, thereby showing no visual indicator that it is selected.
    • The undo button does not work when adding and removing components in an object.
    • Items obtained from the store are improperly scaled when drag and dropped into a Sansar experience.
    • Objects can be scaled beyond their maximum set limits.
    • Some store objects that rely on the emissive.exr texture to be used as their diffuse color are being tinted by the empty diffuse attribute, making the object appear dark and dull.
    • The sound effect for manipulating the gizmo handles have a noticeable lag. This may make it seem like the gizmo is slow in response to your mouse clicks.
    • Reloading a scene after deleting an object will cause the Scene Objects panel to reorder.
    • Additional containers (and its components) that have been added to objects do not move with the object while visiting an experience.
    • Sansar will crash if an fbx file contains 4+ vertices which are all stacked on each other.
    • A scale gizmo appears on light components even though light cannot be scaled.
    • Light objects can be scaled after a volume component has been added to it even though light cannot be scaled.
    • Animated objects have an "IsDynamic" properties option, which doesn't do anything.
    • Crash upon saving a scene.
  • Materials editor
    • Attempting to upload an normal map to an object that has no default roughness will result in an error that does not specify what required texture file is missing.
    • Non uniform repeating textures do not repeat with the designated values (Ex:2x5) and when used will only repeat the lowest value (Ex: 2x5 = results in a 2x2 repeat).
    • The material editor will appear to open then close if an unsupported object type is set as a .fbx file extension and loaded into the uploader.
    • When an object with more than 1 UV map is uploaded, only the first UV map will appear textured. All other UV maps will appear black.
  • Media surfaces
    • Media Surfaces continue to play for a few seconds after entering Edit Mode.

      If a media surface source is set to a gif image, that image will become squashed into one of the corners of the surface. If tiling is used, the empty space will also tile along with the image.
  • Visit mode:
    • Dynamic objects appears offset from the hand you picked them up with. Additionally, tossing and catching dynamic objects may exacerbate the issue and make the objects float a few inches away from the avatar hands.
    • Teleporting using a teleport script into an enclosed space from an unenclosed space causes collision culling of the room and it's contents.
    • Sansar App briefly stalls (150ms per avatar) when other avatars join the experience.
    • At times, some lights do not bounce diffuse colors correctly. Bounced light may not show against the ground or walls.
    • Some emissives in Origin Cinema 360 aren't emitting light after Global Illumination upgrade.
    • At times, some lights do not bounce diffuse colors correctly. Bounced light may not show against the ground or walls.
    • Selecting a container or component in the scene objects panel may cause the panel's contents to shift.
    • At times, crashes may be experienced when switching between experiences.
    • Black patches may appear over objects in a scene while visiting experience.
  • People app
    • Message and Mute options are available when searching for the currently logged in user in the People app
    • People App button fails to highlight when users receive friend requests.
  • VR mode
    • Toggling from the first person to the third person in VR mode may cause the avatar to shift to the left or right of its original position.
    • VR selection reticle intermittently persists on screen after exiting VR mode
    • VR UI text unexpectedly changes position when moving panels around.
    • In VR, avatars' head does not match the user's head tilt and is slightly off.
    • In VR, male avatars using VR controllers appear to lean towards the left side when the controllers are active.
