Hello everyone
Attached is my MEL script that will allow you to setup Multi channel / multi UV tiles out of Mudbox and into Maya with few simple clicks
Important Notes:
A- When ender with Mental ray > make sure you enable “use Maya style alpha detection” in your preference window
B- Tiff files that are created in Mudbox 2009, have a LZW compression. This compression is not supported by mental ray .
Solution: use open EXR or convert these TIFF to another TIFF without compression using Photoshop (CS3 and up)
To Install the MEL :
Copy the icons folder to your X:\My Documents\maya\XXXX\prefs\icons
Copy the script folder to your X:\My Documents\maya\XXXX\prefs\scripts
In the command line type Ash_multi();
To use:
Select a surface and run the script.
Choose a file from the exported/saved images generated from Mudbox 2009.
The MEL will recognize the files based on their naming convention
Each file will be placed in the appropriate UV tile based on their name.
Once you hit create, a shading network will be assigned to your selected object.
Special Thanks goes to everyone helped fixing my BAD MEL
