all good, i figured it out in a very convoluted way

yeah sorry about that idk how to fix that files wise, but all you have to do is download submaterial tool, go down in your spawn menu to browse materials, click on it till folders show, click addons, find improved sniper, double click it for head to drop down then you right click that, copy it to clipboard and in the sub materials menu where it says mat, all you do is paste the copied material there

can you make a tutorial vid showing how to fix the missing head texture?

You could also add these physics. Although I don't know how you could do it, maybe consult with the author; he always answers any questions.

I know there is a model here in the workshop, but the only problem is that this model does not have body groups for the shoes. However, the one I sent in the link does have them, even for his backpack and the bandages on his hands. It is very customizable.

will say that there's also a high poly scout which is essentially the same [not gonna stop me from porting tho]

yeah sure man, ill try, i cant say that it will except a phy's file but ill try my best, if it isnt it might be the same with the sniper till big man is able to get enough free time to make the model except phy's files

Hey dude, could you port this one for the next one too? It's actually by the same author who made this sniper model. I'd like it here, since I've been waiting for someone to port that model to GMOD for a while.
