Two seperate questions, shown by the title:
1. I'm using VIDE and want to pack a custom particle. How should I do this? The manual Add option isn't helping, unless I'm messing up somewhere - I'm trying to pack the .PCF and the <mapname>_particles.txt. What could I be doing wrong?
2. How should I go around using Propper for TF2? I've followed the instructions at https://developer.valvesoftware.com/wiki/Propper#Installation however once compiling, I get the error "Could not get the material system interface from materialsystem.dll (f:\propper\mp\src\utils\common\utilmatlib.cpp)". How should I fix this, and is it because I am installing it improperly?
