Can't (de)serialize btConvexTriangleMeshShape #2241

Closed mschneider closed 3 years ago

mschneider commented 5 years ago

When a btConvexTriangleMeshShape is serialized it falls back to using btConvexInternalShape::serialize which doesn't store the vertices constituting the triangle mesh.

Also the btWorldImporter doesn't support parsing this kind of shape from a .bullet file.

This shape type is frequently used in movie making (e.g. with cinema4d), what would be the best way to enable the missing functionality? I would be very grateful for some rough implementation guidelines.

We are getting some traction on this issue inside Maxon, and would like to move forward and tackle this bug in the next week. @erwincoumans could you provide some more info on this issue? What would be your requirements for accepting a patch?
