Ok... I know... I'm new... I know nothing...
Anyway, I edited alyx's skin (I made few purple dots) and everything worked fine. Next, I made a whole new skin. But now the model looks very strange, purple and black. What did I mess up this time?
the skin you've put in probably has wrong settings, when hl2 cant find a skin for a model, it changes to purple and black squares, its just your custom skin, did you do anything differently to the first time you edited it?
I did nothing different... though is it possible that it's not working because I may have put color to that black area where was nothing in the normal skin??
Look in the folder where you put the skin and delete any vtf files you didn't create by hand.
There was no vtf files... The only one was the one that I put there...
Sorry. I meant VMT.
no VMT either :S
