"Thanks for reporting the problem. It seems random color texture uses the object's geometry to compute random seeds, so in this case it generates different values because geometry is non-static.

Unfortunately we cannot fix the problem. This is something should be checked by the Otoy team."

We are planing to use special seed values per instance which should be constant from frame to frame. At the moment there is no way to keep color with changing object number.
