Okay, so I’ve been trying to make a tunnel model for a Gmod map, so I made this as the collision mesh for it in Blender:
However, after compiling it, it’s like this in-game and I cannot walk inside it or place any props inside it, as it is “blocked”:
I’ve made sure there aren’t any double vertices and that my QC file has $concave and $maxconvexpieces 1024, and run studiomdl with -fullcollide. However, it still does not fix the problem. Any idea what’s going on here?
