SFM Crashes Whenever I Open a Certain Map or Model!
This happens due to some reasons:
- It has one or many incompatibilities with SFM, especially if it's from GMOD Workshop (I warned you!);
- The model/map is too resource intensive for your PC, SFM or both. You have to consider that like the original Skyrim, SFM is a 32-bits software;
- It has missing parts, like model or texture objects mostly due to incorrect installation of them;
- You've installed your models on "usermods" or another folder where you aren't supposed to install models and maps, did you ? This will be the least of your troubles...;
- Your installation got corrupted somehow or you got the infamous "CUtIRBTree overflow!" error.
