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.
