One problem I've had with recreating a building for Sansar is the height of steps, from the top of one step to the top of another.  Currently in Sansar, the difference needs to be under 0.2 meters to have any chance of the avatar stepping up.  It should really be at least 0.25 meters or below, which is 10 inches.  Somewhere just under 0.3 meters would be even better, just to be safe.

I've attempted to recreate steps that are 8 inches apart, which is just a little too far for Sansar.  Of course, we can always use a separate physics mesh that's basically a ramp.  But it's more real to be able to stand on individual steps, and the point of virtual reality is to feel like you're really standing on a step and not an invisible ramp.  So I have to use 0.15 to be reliable for the avatar stepping up.  The big problem with that is that it requires more steps, and therefore a larger horizontal footprint.  It can be nearly impossible to adapt the larger footprint into an existing structure.  So it would be great if the stepping height was increased to allow recreations of real-world steps to function properly.

Yes, agreed! And the ability to do a little jump over a low obstacle would be useful!

Hey guys,

(summary: the stair step height in Sansar is not wrong, as north american building codes state stair height should not be higher than 7 3/4 inches = .2 meters)

I had the same problem when I started making steps here.  My default used to always be ..25 meters for steps as well.  It was convenient, and I felt that a 9 inch height was normal and based on real life.

But, all these years I've had a misconception.  Real life steps are not 9 inches high - if they are built to standard architectural specs.

Apparently, building code for stairs in North America is no higher than 7.75 inches, which comes out to - - - .2 meters.  You can google that if you wish.  Don't make the mistake of measuring steps with carpet on them.  You can be fooled into believing they are 8.5 or more inches tall.

So I went ahead and made my stairs in Sansar .2 meters high, and it feels good.  It feels right.  It makes me feel comfortable, much more comfortable than .25 meters did.

This, of course, presents many of us with a problem.  A quarter meter was so convenient for modular building, because you could go up a meter with 4 steps, or up a half meter with 2 steps.  Easy Peasy.  Now we're faced with a fifth of a meter as a step, and while this is fine for a meter height stair, it presents a challenge for lower stairs.

I will continue to make stairs at a fifth of a meter height.  It feels better for me now.  I'm willing to rise to that challenge to make worlds feel more comfortable.  I once did a live seminar for an IMVU conference in San Francisco that focussed on comfortable surroundings, and the enjoyment and visitability of VR worlds.  Architectural proportions were a major point during that talk.

That said, most humans don't have a problem stepping up even a half meter of height when needed.  So I agree that a larger step-ability should probably be granted.

I agree, the current step height is wrong. i made my steps based on RealLife step height. around 21cm. and sansar refuse to use that step. Mabye it got a bit thicker whit design.. But really it need to be at least 25cm or better 30cm to get up on sidewalks. the can be between 0-25cm easy.

Only not so sure if you like to use real life steps in house with VR.
I think it's a very shaking ride then to get upstairs then.

Yes, pls. change that! 15 cm seems to be working for me. A good collisions can help. I know a VR resident will rather have smooth collision then steps, still, it is not pleasant to build like this. Maybe, as I am in desk mode for now, I might be overlooking VR related stuff. If so. pls contribute.

The long history of step height includes risers that are greater than the current 7-3/4". At one time in my life, I built several hundred homes that included code-compliant stairs that were 8-1/4" high. The stair code changed in the last 15 to 20 years. The code did not change everywhere and not at the same time due to different jurisdiction having control over adoption of the code.

I have made mesh stairs for use in Sansar that are as true to scale as I can make mesh and the rise is 7-3/4" and my avatar can walk up these steps. But I will agree that the real world may have older homes built before the code change and the avatars may not be able to navigate them. Let's call these vintage homes or legacy homes.

What I find to be an issue here is that when going up these stairs, my avatar takes two or three steps at a time. This has to do with stride length. Currently, the animation for an avatar is the same on flat ground as it is on any inclined surface. Machinimatographers will never get good results if they shoot an avatar walking up any stairs and they include the avatar's legs and feet in the shot.

I made RL scale stair steps to between 20-25cm. I wanted 21cm because that is what's used here in the building. It could have be a cm higher. The step size in sansar with 20cm as max is to low.

Sansar need to increase this to 30cm to make it more usefull and not make the limit so crazy high as in secondlife.
