Hello, /r/SFM! Let's try something here.

We get a lot of bug threads here regularly, which is expected and accepted by everyone. However, I'd like to create a thread that contains a fix for most bugs that people encounter in SFM. And you can help! Have you encountered a bug recently that you know how to fix? Post it in the comments!

Make sure to be as specific as possible! This will avoid any more questions to be asked regarding the bug.

(it can also be simple quirks instead of bugs)

BUG: My model is kinda see-through!

FIX: It is most likely an Ambient Occlusion problem. Search the Workshop to see if your item has a fix available, usually by Sync.. If it doesn't, search for your model's skin's .VMT file, and add "$ambientocclusion" "1" to it.

BUG: I want my model to run when I import a running sequence!

FIX: This is what you're looking for. See which option fits your needs.

BUG: WHY THE GRAIN?!

FIX: Ambient occlusion doing good work. If you have grain in your poster, you did not increase the Depth Of Field quality in the Render Settings when right-clicking the Viewport.

BUG: I just added a particle but I can't see it anywhere!

FIX: Hold shift and move your mouse out of the current shot, then release shift to go back to the frame you were.

BUG: My model has black textures!

FIX: Is this what you're looking for?

BUG: $selfillum doesn't work on X model!

FIX: Some models simply don't read the variable. Try using a vector3 $color attribute with 3 very high numbers, it should provide a similar output!

Type yours in the comments and I'll try to add it here.

You can also come here to type a bug you found but you don't know how to fix, maybe someone can!
