My guess: Pose files seem to be aimed at CR2's not PP2's. Your MAT looks like it has wrong info at the beginning. Parent the prop to a figure (a small figure might be quicker) and save the CR2. Look at the header into the section where the materials are defined. For a figure MAT it is: figure { material ##### It may be "prop" but it should be generic, the MAT must first tell which section of the CR2 it is addressing.
