atdsk: Meet the Experts - Ptex painting in Mudbox

From what I can tell, this is the exact same presentation from the webinar a couple days ago...

Mostly focuses on painting and working with Ptex in maya

What is Ptex?  ( to me ptex is how you repair a divot in your snowboard base)

• Per Face texture assignment
• UV free workflow
• Uniform, balanced, smooth texture, layout
• production proven:  Disney/Pixar open source project
• PRman, Mental ray, vray supported.. and some other renderers

Brief History

•  Developed by Walt Disney Studios
•  Paper:  http://ptex.us/ptexpaper.html
• First used in the feature film Disney's Bolt, Nov 21st . 2008
• released open source Jan 15th 2010 http://ptex.us/

Pros & Cons

pros

• instant setup, no need to create and layout uvs
• zero distortion and limited seam issues ( if any) 
• no need to iterate or make special uv setups
• can instantly start texturing, with the ability to export to uv maps later when they are created

cons

• still doesn't support all texture formats
• not supported all render engine and game engines
•  not editable in a 2D package
• vert changes need to update uvs  ( still not sure what the best protocol is on this one) 

and here as promised is the webinar video from ATDSK expert :   Craig Barr
