Troubleshooting
My SFM project doesn't appear in the project browser
If you want to import a SFM project file, make sure to choose "File -> Import..." from the menu bar instead of "File -> Open...". If your project still doesn't appear, and it is located in a custom user directory ("SourceFilmmaker/game/<custom>/..."), you will have to open the "cfg/mounted_games.txt" file, locate the "sfm" entry and add the custom user path to the "game_paths" section.
PFM freezes when loading a project
Importing a project for the first time can take several minutes or more, during which Pragma may appear frozen. This is normal and should only be the case the first time you load the project.
I can't move in the viewport
To move in the viewport, make sure the "Work Camera" is selected instead of the scene camera. Then right click into the viewport, hold the right mouse button down and move with WASD and the mouse.
I get a black viewport after opening a project
I get visual artifacts on a model in the viewport / when rendering with Cycles
If you get artifacts like the ones above, it means your model is most likely using a method called "fake PBR". This is used in some models to create a PBR-like effect in Source (which doesn't support actual PBR), but is incompatible with Pragma and Cycles.
