Question Creating a bucket with DOTS physics

Hi,
I would like to create a bucket like thing with DOTS physics where balls can fall in. But the ball falls through it.
With Unity classic physics it can be done with a mesh collider, but unfortunately the corresponding physics shape with the mesh shape type does not work in DOTS physics.
See the attached screenshots.

 

Use convex hull don't use mesh

 

Thanks for the tip. Unfortunately the convey hull does not work because it creates a drum like collider and the ball cannot fall into the hole.

I turned on drawing the colliders, so you can see what is the generated collider in that case.
In another project where I need the functionality I set up plane colliders to mimic a square hole like so:

(Actually there is a another horizontal plane for the bottom on a different empty, which is not seen on the screenshot above.)
That seem working, but this solution does not follow the round shape exactly

 

We use some tool to convert the single mesh to multiple mesh, then use them as sources of convex hull, a entity can attach multiple PhysicsShape

 

https://github.com/Unity-Technologies/VHACD should be workable as a generator for compound convex hulls that will support any kind of source geometry. It just spits out convex meshes you can repurpose for anything.

There's a documentation md file for further info in the source repo.
