images as textures

Hi All,

I thought I should ask my question in a new post. Any help much appreciated...a full on noob here!

Ok, I simply want to use a photo/image as a texture on a cube or rectangle, as soon as I can do it...my ideas are possible. An old project in SL brings me here but I'm no 3D modeller.  If  anyone reads this and can help it would be much appreciated. Here's how far I have got; (using blender)

I create a plane, then click on material, tick shadeless, click texture, open new (image), ensure mapping set to UV, then open UV editor, unwrap and ensure image is in the mapping points, I then  go back and ensure the camera is directly over the rectangle image, I then render the image and it looks fine. I then export as fbx file and then upload to sansar. The only material combination that lets me upload without errors is 'no texture'. Finally when I try and use the object the image isn’t there!

on further investigation I understand I do need to create this texture file separately is that right? (if it's being lost when exporting the blend file to fbx) 

am I missing a tiny little box that needs to be ticked in blender?

Any help much appreciated!...and thanks for the free stuff in the store!

  ...Hi Charmarley, your texture is in power of x2 right? like 256x256 or 256x128 ? ..your texture is png? if texture is already assigned to model in blender it should upload automatically..

  yes it is, now I've just added the texture to two sides of a cube, and those two sides have come out white and the rest of the cube black?

  Here's an image of the cube in blender (rendered)

  

  and when uploaded

  did you check material editor to see if its albedo slot? if not, select it from there to upload...

  In texture preview can you see both texture and material? If you cant see material but you can see texture there is where your upload problem is occurring. I can reproduce your issue by not selecting new material during the process.

  this is what I can see. If I select the heavyweaponry as shown I get an error message and if I select no texture file I get the above plain white sides

  ..was your shader in blender set to phong?

  I can't find a 'shader' option in blender? there's 'shading' over on the right when 'material' ball is selected?

  brilliant now I see it. So I'll try everything again as it was NOT set to phong!

  thanks! fingers crossed!

  Charmarley, any other 3d apps you've tried besides blender?

  Are you exporting out of Blender with the texture assigned?

  I've had issues with models when I assign the texture to the model on export from Blender.

  When I unwrapped, then took the UV to PS and textured it, I didn't assign it to the model in Blender, just a material w/phong, then when importing to Sansar, I assigned the texture to the model and it works fine.

  Try your normal workflow, but don't actually assign the texture file. See if that works.

  Hi!

  No, no other apps used, blender was free hence using it as a starter.

  Chris yes I am trying to export out of blender due to not having photoshop. (I just spend £700 on a new laptop to get into sansar! - gtx1050 needed

  so the "taking the uv to PS" I don't understand

  so I've just started again. Trying to build a wooden door.  Here is the png of the door:

  here's the door mapped ok (I think doesn't matter if a bit off for now) in render

  only one side for now as I just want to see the image in sansar, once I've done it once I'm rolling!

  then here's the default view;

   

  

  and after I hit render;

  Charmarley Nightfire July 20, 2017 11:12

  so finally, when I upload in sansar, I do have the option to select the original png image shown here;

   

  

  and so I get this error message;

   

  

  so it is to do with that texture 'missing'. If I select no texture file it will upload the shape and go in my inventory but the image side comes out black.

  Once again any help much appreciated. I know this is probably the most very basic stuff but it's got me into a right pickle.

  Is there somewhere else I can create the texture files? 

  Thanks

  Charlie

  I had this cache hit miss just a few ago, my solution was using base 2 width and height on my pic dimensions, so make sure your texture is a nice binary number like 512, 1024, 2048, etc

   Also you shouldn't need to add it as a material since it's coming in with the .fbx. At least I haven't had to.

  sorry by base 2 do you mean I should resize my door image to say 512 width x 1024 height (short fat door) and try that?

  Gindipple July 20, 2017 12:06

  yes something like that

  base 2 is binary, numbers go 1, 2, 4, 8, 16, 32, etc

  base 10 goes 1, 10, 100, 1000

  people like base 10, computers like base 2

  Have you tried uploading to Sansar without using the material settings option for the upload in editor?

  I dont use the material settings when i upload my textured Fbx file and it works fine.

  didn't have time earlier, but just wanted to say thanks to all for your help.

  Just to let know, I’m fine and have found the problem. On an earlier tutorial I watched on youtube 2 days ago (adding images to a plane) an early step was to tick the ad on ‘import/export images as planes” and then forgot to turn it off!

   

  agonising for two days but at least I learn an alternative way of doing it!

   

  Thanks again...hope to see you in there sometime
