Unable to remove materials from renderers.

I’m unable to remove the materials from any of my objects. I can’t highlight the material option or anything. The blue bar does show up but won’t stay. Unity deselects the material. Why do I want to remove the materials? I only need the wireframe itself for collision detection.

EDIT: The only current way to remove the materials is to remove the renderer as a whole and just leave the mesh collider behind. The object does not stay in view on its own which makes a few things difficult. Not sure if ill use this option.

System info:

  • Unity 4.1.5f1
  • Windows 7 Ultimate
  • Gigabyte GA990x-UD3
  • AMD Quad Core 3.60ghz BullDozer
  • 8GB g.Skill RipJawz Ram
  • Evga GTX 660 2GB Ti OC

Click on the material selector and select “none” from the list. However that causes the object to use the “hideous purple null material” appearance in order to make it very clear that it hasn’t got a material, which doesn’t sound like what you want. If you don’t want a renderer, then just disable or remove the renderer component.
