Terradome 2 Alpine textures

druc

I have TD2, bought when first released over at RDNA. I use Poser Pro 11.1. I have mainly used the dessert scenes, sometime water and have had brilliant results. I have just tried the Alpine textures and found poser hangs (stops responding) if I have characters in the scene at pre calculating subsurface scattering, or without characters at the render stage. The scene is the same, it will render as normal with dessert textures, crash if I change to Alpine textures. Is this a known problem, and is there a solution?
