Give each vert a random vertex color script in Maya
May 28, 2022
Here's a mel script to set the green channel to a random value. Select a mesh or meshes then run it. Change the numbers after "rand" to constrain the values. -g can be -rgb with 3 numbers after it to set all rgb channels.
string $listOfObjects[] = `ls -sl`;
int $i;
for( $i = 0; $i < size($listOfObjects); $i++ )
{
int $eval[] = `polyEvaluate -v`;
int $numVertices = $eval[0];
int $v;
for( $v = 0; $v < $numVertices; $v++ )
{
float $rand = `rand 0.0 1.0`;
polyColorPerVertex -g $rand ($listOfObjects[$i] + ".vtx[" + $v + "]");
}
}
