Mocap: Can you email me the shape you formed in Amorphium. I have just the demo and I created the same object but could not test 'cause save is not possible with demo. I tried other imported objects but bryce but volumes just render incorrectly - as if they were volumes turned into solids. Put Clay's fire mat and make it a volume. That produces a strange tv noise type of render - totally wrong. Any way teh rock/stone method appears to work. I notice you have Lightwave. What are the pros and cons compared to Bryce?
