Bloody Human Remains Rigged Low-poly 3D model

I'm suprised that cgtrader allow to say one thing and show them on screenshots but asset is different thing. I wish I could add screenshots what is actually inside. So each part have got separated textures but not for all models. There are not textures for nose and each finger. I tried to put other materials made with provided textures but uv maps not match. Also not all models you may see on screenshots are provided when you buy it. There are no torso for example. So you can use legs, arms, head, body and ear but they are all on separated maps. As a game developer since 2013 I can say that models are not optimized for games. May be good for renders. Waste of money.
