The Last Stand's pack i included maybe is a little unrealistic or not very appropriate, but i included it in cuz that's the one i use and i really like how it sounds related to the 57, so it's all for your amusement and client improvement =)
I would like to have a better lightning effects over the v_model but editing the textures to look like polymer (which is actually an smooth material) just left the GoldSrc engine's lights dynamics or whatever it calls doing the whole lightning work, not too advanced but it's all can be.
Sorry cuz i was not able to upload more screenshots of the whole pack! But i tested it completely and i can surely ensure that all parts works properly.
