I want to create a mold similar to a phone screen protector, so it needs to be made of a slightly soft material. However, in version 5.0.0, it shows “(deprecated),” and I’m not sure if this affects its use. Although I still use it, an “air wall” issue occurs. How should I adjust it? This problem appears even in the simplest scene (cube, ground).
Steps to Reproduce
Using the Isaac Sim UI
Create →Physics→Ground Plane
Create →Mesh→Cube(Add→Physics→Deformable Body)
Play
You can observe an “air wall” between the ground and the cube.
Yes, it happens every time, and you can observe it by checking the Z-axis. So, does the “(deprecated)” status of deformable body mean it does not affect functionality? Additionally, I tested in three environments: RTX 3070 Ti with driver 550.163, RTX 5080 with driver 575.64, and RTX 5090 with driver 570.172, and the issue occurs in all of them. Below is the model we tested, from which you can see that the issue does not occur with rigid body but does occur with deformable body.

Can you try the new Deformables Beta feature in 5.0.0?
Deformables Beta
PhysX supports a new schema for volume and surface deformables, replacing current particle cloth and deformable body functionality. The beta feature set can be enabled in the physics preferences:
Of course, I’m very excited about the new Deformables Beta. I followed the tutorial to enable this feature and reloaded the stage, but I couldn’t find anything about the volume deformable body. Additionally, using the surface deformable body results in an error and cannot be used.
Could I have missed something? Or is there any tutorial for the new Deformables Beta that I can refer to?
Thank you!
The error means that the mesh assigned as a surface for a deformable body contains polygons that are not triangles. Isaac Sim (and PhysX) requires that meshes used for deformable body simulation consist entirely of triangles, not quads or other polygons.
