Feedback Add V-HACD library to unity

In any project you need to make colliders for meshes, but now the choice is only between primitives (BoxCollider) and MeshCollider. MeshCollider is not suitable for large projects on mobile devices.

Add the golden mean!

Supposedly it's in the Roadmap:

https://unity3d.com/unity/roadmap
(find "Automatic Convex Decomposition" under the Development section)

But it has been there for some years now, so I wouldn't expect it to be available anytime soon.

 

Bump, because it could be very good addition.

 

With the new Unity roadmap, I wasn't able to find it on their list anymore (I may have overlooked it though as the new roadmap is a bit difficult to find things).

I found this Unity GitHub repository for VHACD integration into Unity - https://github.com/Unity-Technologies/VHACD

But it seems like it was currently incorporated only for URDF import and not for other file types - https://github.com/Unity-Technologies/Unity-Robotics-Hub/blob/main/tutorials/urdf_importer/urdf_appendix.md#Convex-Mesh-Collider

There may be a solution for other file types if someone digs deeper into the GitHub repository.

 

Why should they add it ?
After all who needs Proper Efficient Collision Detection for Dynamic Rigidbodies in 3D games engine ! ?

And I second the question: Have you found the way to do it, except AssetStore solution.

 

I'm trying to use VHACD. We found the following " It can support any mesh as long as you can extract the triangle info from it which I was able to do with the STL files. Problem is, is that it returns an error that the package is missing when you run it in a webgl build so it seems like it isn't supported for webgl." suggestions?

 

Is it possible that VHACD is Windows-only? I'm on a mac and we would love to use it in our Windows/MacOS/Linux open-source project.

 

Is there anyone who knows how to use it? I have model like a bowl in Unity that I created in Maya and I put the script VHACD on my bowl with a mesh collider... enable convex and it also has a rigidbody. What is the next step or do I have to to something in Maya first? It still puts a "top" that covers the hole...

 

You can install it as a local package, that worked for me.
https://docs.unity3d.com/Manual/upm-ui-local.html

Open the folder an go to com.unity.robotics.vhacd and choose the package -file.

 

Have you figured it out ? This is crazy, no documentation, nothing....
