Trouble with collision in procedurally generated .dae model

[Borogove]

Has anyone had success procedurally generating collision mesh for 0.22?

I had my procedural parts working in older versions of KSP (~0.19?), but the collisions seem to have gone away when I bring it into the current version.

I'm generating .dae files, my collision node is called "node_collider". Googling suggests that this name is deprecated, but I'm not seeing how to mark the collision mesh in a .dae.

The collision mesh works in the VAB (I can attach pieces radially to arbitrary points on the mesh) but the parts (fuel tanks and engines) just sink through the ground when I try and land a rocket built out of them. Interestingly, I can land it on the launch pad -- maybe mesh-to-mesh collisions are working but not mesh-to-terrain?

dae importing as a whole is depreciated.

The behaviour you describe sounds like your mesh might not be convex, if you want a non-convex collision mesh then it's more reliable to make it from multiple convex shapes.

[Borogove]

It should be convex (it's a simple cylinder), and as I said it used to work fine in older versions.

Is there any reasonable way to programmatically generate .mu files? I'm not a modeler, and my system generates *dozens* of parts; I have no desire to deal with manually touching all of them.

I'm gonna try to adapt the .mu export code from this add-on. Wish me luck.
