Probably a long shot but I'm really stuck on this. I'm working with the xgen interactive groom editor in Maya and trying to add collision to hair guides. By default they collide with the mesh they originate from but not other meshes in the scene.
According to
this Autodesk help page you can add collision modifiers to hair guides but it doesn't specify how, simply says "Add a collision modifier".
The problem is that I can't find collision modifier anywhere. Below is a screenshot of the modifier list.
If anyone has any idea how I can do this, please let me know, I would appreciate it. Thanks
