I'm pretty new to Hammer, and I've been working on a map for Garry's Mod (even though this site is called "TF2Maps." It's a building map for complex vehicles. The map isn't very large at the moment, but I'm still running into a weird problem. When I compile with VIS, the lighting is fullbright, but there are still dynamic shadows; like from ragdolls or props, but the buildings don't cast any shadows. There are also weird "holes" in the ground in one specific spot. It still has collisions, but it's invisible. Any help at all would be appreciated. I can also give you the map file if you want. Also, there are no leaks in the map. I've checked.
