Cloth Room sim randomly corrupts materials settings on multiple figures in a scene.  I ran a simple cloth sim, one garment to one figure, and the materials went kablooey.  Initially it seemed to be an issue with Poser no longer reading some portions of the figure geometry, when a transparent material was assigned to the main body skin material.  Upon running a second sim, after saving a reloading the scene file, the same materials swapping occurred, this time revealing that the trouble was materials and not geometries.  Two shaders from the figure involved in the sim (an Antonia) were randomly assigned to all materials in both Antonias in the scene.  The attached shows the second sim.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
