I recently followed the tutorial: https://www.youtube.com/watch?v=HUU1Cv8ibjI&t=457s as far as I could, since some source filmmaker updates can make this difficult. The sounds, models and scripts from the L4D2 game are already added to the program. BUT the problem I have... is that I can see the model rigs, but not the characters, props, vehicles, infected from the game. I mean they are there! but they are not visible. If any current L4D2 animator has already solved this problem, I would really appreciate it if you could help me.
