[selimanac]

I’m not sure if this one still works but there is a py script for Blender.
see defold_mesh.py in this example: Mesh Component

Here is the discussion:

Custom 3D collision shape

This is great! For 2D .convexshapes PhysicsEditor works well. Is there a similar tool that can be used to generate 3D .convexshapes?

Using a DAE mesh for collision

Here’s a quick guide to converting your DAE mesh into collision objects using Blender and dae2collision. Note This has only been tested with a simple model from Blender 2.93 using (probably) default settings. Other setups will hopefully work, but no guarantees. Preparing The Model Since Defold doesn’t support concave collision shapes, we’ll need to split our model into convex pieces. This, unfortunately, must be done manually, as I haven’t found a working way to automate it. To split a mesh …
