This used to work for me, but I have found that when painting a boxm2 model (using scene.update_app()), python is crashing.  I think it has to do with the apm being "boxm2_gauss_rgb", because it doesn’t happen when apm is “boxm2_mog3_grey”. Has anyone noticed anything similar when either updating only an appearance model or using boxm2_gauss_rgb?
