If you are experiencing crashes, have these in mind :
parameter names beginning with normal or color crash massive's DSO.
if you have any of those, use the CONFLICTING keyword before them to fix it.
"normal_map_filename" ["../maps/shader_maps/prman/colour/sweatshirt_color_'sweatshirtmap'.tex"] "color_aov" ["color"]
should be rewritten as
"CONFLICTINGnormal_map_filename" ["../maps/shader_maps/prman/colour/sweatshirt_color_'sweatshirtmap'.tex"] "CONFLICTINGcolor_aov" ["color"]
