There are currently two "types" of tiles that don’t work. One is sort of working if I flip the normals the right way. The other one though, so weird that it doesn’t do anything actually. I checked it’s points and the normal. All seems fine except when playing the game it doesn’t collide at all.
So I have to zoom in on that specific tile type and then see what is causing that. Hopefully that will point me to the root cause of all this. Since the code seems to work fine for everything else.
