I have three questions about this:
When we apply the “rigid” attribute to Xform, I guess it was applied to the “mesh” which is the child of Xform? or applied to the Xform?
why in add physics menu, “rigid body” and “rigid body with colliders preset” in gray?
Usually , the collision bound created in Omni is red, But I import the URDF with collison description, it is in green.
If I can not create “rigid body” because it inherited greed collision boundy from original URDF? How can I remove the green bound box?
Thank you !
For 3. how do you get the collision bounds to show? I’ve used Physics Debug>Simulation Debug Visualization>Collision Shapes, but the bounds are drawn in pink instead of green or red.
I guess green bound was inherited from URDF， but not inherit collision from omni system.
Describe the collision in URDF.
You would have to use the inbuild collision visualization based on USD data:
The Physics Debug>Simulation Debug Visualization>Collision Shapes actually displays debug visualization coming directly from PhysX SDK, those colors come from the SDK directly.
