Has anyone noticed a change in rendering characteristics comparing 5 to 4. I'm working with the demo now and I getting really harsh colors even when lightening and varying the color of ambient light, both material-wise and the sky, as well as shadow. I've noticed this in Bryce5 imagery by others and am wondering if there might be some not so subtle changes in the engine. It is particulary striking in the Treelab. Also the foilage is not particulary defined. manowar
