How to render your Mudbox file in Mental ray

"How to render your Mudbox file in Mental ray" by Ashraf Aiad
In this tutorial we are going to explore “how to” render the low poly mesh that was exported out of Mudbox with mental ray for Maya , and match the same number of polys of the high rez. model in Mudbox.

3Dtutorials.sk recommendation:

To maximise the realism of your 3D rendering we recommend using high quality photo references from the #1 texture websites www.3D.sk and www.environment-textures.com

This approach is considered the most forward and easy to understand.
Open your Mudbox file and note the number of polys that your mesh has.
This number is located either in one of these 3 places.
1- The “HUD” highest level Display info
2- The Status line at the bottom right corner of the UI.
3- The Object info tab

Step down to the lowest Level
Export the low poly mesh as an OBJ
In Maya, open the option box for the OBJ import and disable “create multiple objects”, thus importing the mesh as “one” unit.

A good practice would be double checking the UV integrity to insure NO broken UV edges or flipped UV shells.
This can be done by opening the UV texture editor and toggle “Border edges ON” and “Shaded UV “

1- Example of broken UV edges
2- Example of flipped UV shell

Select the mesh, and click on ‘ctrl’ + a to open the attribute editor.
Under the shape node for the mesh, disable the “feature displacement”.
