Firefly, As i said in an IM to you, thank you for your appreciation of my work. I owuld like to add here how i handle "bump" I found bmp a mystery, when i started this application of fractals to Bryce over 4 years ago. Now after trial and error, I use contrast while creating the fractal and KPT convolver while still in Photoshop. I adjust the "relief" setting in Convlover...I have learned to do this in a very delicate and ginger manner, elsewise OH Wow to i have some bmp in Bryce...LOOKOUT! In Bryce I import the 2D fractal using it as its own bmp. Truthfully, I can go on at the mouth for hours bout this stuff...oh well, guess that's me LOL :-)
