I agree that P5 is loaded with a lot of new and useful features, but it is dissappointing that what seems like such a simple task was overlooked. I think to be honest, most users of poser are not going to delve into the materials room and use it to it's full advantage, I think the majority of it's users are those that just want to make pictures "out of the box" and rely on mat pose files and prefabricated models/props. Poser 4 materials room was simple at best, P5 is definately more difficult and dare I say the word "intimidating" even for me, a long time user. I've been suggesting since poser 3 was out to be able to have the ability to simply pull down the materials list, click all the materials I wanted to manipulate at once, lock them together and apply the attributes I wanted to apply. I make figures and props that have several material names and it's bloody murder going through every single material, one at a time, to apply a texture. The apply to all doesn't always work for me because I have multiple textures per figure and I use reflection maps on several of the textures as well. I'm not a programmer, but it seems that this is not a complex request. Maybe even a "revert to poser 4 materials editor" would come in handy in a bugfix.
