Modeled with Autodesk Maya 2016 using polygons.

With materials and textures.

All the objects parent and group correctly.

Mental Rays Mia Material X is used for all objects in the scene. The file called ' render ' is to render like the first imatge with Maya Mental ray. For best results add a render occlusion on it.

Formats mb,, fbx, obj and 3dmax.
These formats with basic materials and textures.

I also give you the psd file for the sky composition.

Thanks for your support.
