Well I only have a pale idea how to use it. For me it is like when pilots used to fly by the "seat of their pants"....I have some tutorials, but I didn't take the time to read them. I just try this and that, and always *save* even if the next one is only a fraction different then the one before. Same with the lighting. I have a 5+G folder of my mandelbulb parameters, lighting and images....and I must get it off my pc!! Thank you Jan, it is a great compliment from you that you are using it!!!
