This is a motor, as one might see in a derelict factor.
The asset was created in 3ds Max and setup to render with V-Ray 3.6 or greater.
The asset is one element from a greater collection of elements that all share a small library of shaders. The asset uses multiple UV channels with tiled maps in the shader. Each shader then uses a mask file to provide a unique, non tiled look. The masks are saved into a single PNG file. Each PNG file contains three masks in the R, G, B channels for economical use. Max then uses one of these channels in a Vray Blend shader to influence the tiles.
I've also provided; OBJ, FBX and ABC. These files are setup with a single generic UV tile for flexibility in other programs. Note because this is aimed for general use, the shader / maps are different and will render different to the version setup for 3ds Max / Vray. Not any less good; just different.
I've provided a Cinema 4D file. Please note this was created using a 3ds Max to Cinema 4D Converter.
I've provided a 3ds Max file with all the Factory Element shaders in one scene for alternative use and flexibility.
All shaders were created in Substance Painter.
As noted above, this is one element from a series of Factory Elements that have a derelict feel. Please see my other products to discover the other elements in the collection.
Preview Images were rendered with VrayRT, a single HDRI skydome, and a single rectangle light.
