Importing OBJ files into Blender

[Common Commando]

I'm importing OBJ files from Valve's workshop resources into Blender; however, some weapons are missing parts of the model.

Do you know what could cause this? The same OBJ file works fine in Substance Painter.

Hello Common Commando,

I have used GMAX from https://www.turbosquid.com/gmax in the past to import OBJ files with no problems, I'm not sure about Substance painter I am almost certain its a subdivision issue with your models though. That's what it usually is.
