 26-06-2003, 11:19 PM #2 kbrown Moderator     Join Date: Sep 2002 Location: London, UK Posts: 3,198 Thanks: 0 Thanked 8 Times in 8 Posts It's a vector variable so you write it: lamMAT_matrix.color = << r, g, b >>; where r = red, g = green and blue ranging from 0 to 1. Black would be << 0, 0, 0 >>, white would be << 1, 1, 1 >> and mid green would be << 0, 0.5, 0 >>. Get it? __________________ Kari - My Website - My IMDB Do a lot, Fail a lot and Learn a lot!

First, thanks for your help ... i did it befor that way as well, because i found this expression for a vector in the maya help, but it tried it and maya gave me this answer (to the exact same line you wrote) : "Error: Attributes must be of float, integer, or boolean types: color" ... and thats what i don´t get ...the rest i am familiar with from photoshop. do you have any idea why maya doesn´t accept that line ? -train~

It's a float3. You also (may) need to use the setAttr command: setAttr lambert1.color 1 1 1; Sorry, my bad... __________________ Kari - My Website - My IMDB Do a lot, Fail a lot and Learn a lot!

Look in the Node and Attribute Reference to see this stuff -- these attributes are listed on the page for the Lambert node. -- Mark __________________ Mark R.
