I tried creating a new mod. I want to make a map to test the weapons, but whenever I launch hammer, this happens:
None of the grids move, no matter what I do with them. I can’t place brushes or entities, either. When I first launched it, it said I was missing materials/editor/flatignorez.vmf, so I took that from the HL2 VMF. It fixed it, but I think this is a texture problem.
