'But if you look, I think it's the first Material in the file, .cr2 or whatever, which is the default' Yep. The material order in the poser model is defined by the order which the materials appear in the obj file. Nothing you do in poser can change that order (short of inserting a dummy part in the obj with all the materials listed in the order you want). The only real reason for having a Preview material is for an obj with no materials assigned to it. In that case, everything gets lumped under Preview. But if CL could be bothered, I'm sure they could figure out a way to have it NOT display when other materials are present. It's the old story. Minor irritation. Not important enough to fix. And so these things accumulate from one version to the next. mac
