I think it may be something to do with how the Poser 5 versions of the .cr2 are saved. Poser 5 stores each material/texturemap combination in two places, first in the same way as Poser 4, and then in the shader tree data for that material. What I think is happening is that the P4-compatible entry stores the full path -- ":Runtime:textures:etc:filename" The shader tree entry sometimes comes out as just ":filename" And that is what seems to break things. (Make up a .cr2 with some distinctively-named texture files, and have a look for the filenames with the search function of a good text editor.) I'm not sure why the save should be different. Looking at how a texture file is selected in the Material Room, it seems that there can be two different references for the same file in the picklist -- one with the path and one with just the filename. Maybe it depends which you pick? Using CorrectReference seems to cure a lot of the problems. If you don't have it, go to the link: the original free version is downloadable from the site's front page without any hassles. I'm not a 100% certain that I've nailed down the problem, but I think I have a partial answer now.
