this is the first skin i have made for half life source it is based on the black mesa source barney enjoy p.s this is for the HD barney model from the hd pack if u don't have it you can't use it. textures by half-dead
Functionality: Everything seems to work just fine, it doesn`t affect the ingame or something.
Realism: Well, I would say this look for barney is more realistic than the default, the pockets in the vest are very paractical, the default barney doesn`t have any pockets, and also thos knee pads are quite a good addon. Looks more like an actual security, but maybe it really isn`t the right criteria category to choose here, you should have used maybe originality, or detail, idk, but don`t worry.
Texture: This texture is pretty cool, I really liked how you recreated the BMS look, but looks quinda low res, I don`t see normal maps and the vest texture looks like there are some misplacements in the part of the neck hole, and the knee pads should be placed a bit lower I think, overall is pretty good idea.
Btw, you should add gearbox and valve to the credits anyway.
