Comments on: Maya Python Script : Control Point and Vertex Colour and Massive confusion http://www.hodge.net.au/sam/blog/2010/01/16/maya-python-script-control-point-and-vertex-colour-and-massive-confusion/ Random Thoughts of Sam Hodge, about Life, Art and Technology Sat, 02 Feb 2019 04:05:58 +0000 hourly 1 http://wordpress.org/?v=3.5.1 By: Simon http://www.hodge.net.au/sam/blog/2010/01/16/maya-python-script-control-point-and-vertex-colour-and-massive-confusion/comment-page-1/#comment-480 Simon Thu, 31 May 2012 16:33:44 +0000 http://www.hodge.net.au/sam/blog/?p=176#comment-480 I realize this is out of date now but I managed to have some luck when using expressions to take the RGB from the texture UV. The Python command has a flag to update frame for frame: cmds.expression( o=i, ae=True, s=”…”)

here’s an example of the expression that you might end up with:

$foundUV = `polyListComponentConversion -fv -tuv FollowMesh_T.vtx[0]`;
$uv = `polyEditUV -q $foundUV`;
$RGBColor = `colorAtPoint -o RGB -u $uv[0] -v $uv[1] FollowMesh_Texture`;
FollowMesh_T_Locator_0_000.tx = $RGBColor[0]

Thanks for the head start, keep up the good work! :)
