All right, I looked into the issue. It appears that only the wooden platforms were having issues. I also noticed that some maps would render the platforms correctly, whereas some would not at all(construct was fine, all flat was black all the time). It appears to be an issue related to level lighting and the VertexLitGeneric shader.

I think I've cleared up the issue. For whatever reason, the materials for the platforms had phong turned off. This resulted in a weird lighting issue where the model would go full black if you moved a certain distance away from the prop. Moving the prop with the physics gun would temporarily fix the lighting problem.

Phong is now reenabled for these props, which hopefully fixes this issue for good. Get back to me when you can and tell me if it's working on your end.

Thank you so much for fixing this, I really appicted it :)
