So you've extracted a custom model for SFM but when you go to use it you find that the materials are Black and Purple Checkerboards. Well that is the default material for a model that the game engine can't find a material for.
This tutorial will take you through a couple of reasons why this is happening, where to look to investigate the problem and suggest the fix.
