Steve, >>>in cookie cut mapping the background (ie:the part you want transparent) should be pure white (255) for totally transparent and black for opaque…. It sounds as if you are describing a transparency mapping not the cookiecut… My understanding (and experience) of cookecut is that it is a simple color bitmap. From reading the manual I understood that there is a single "background" color in your bitmap will be _Totally_ transparent, and all other colors would be _Totally_ opaque (and this is another clever example how simple and unique this program is). I did some experiments trying to figure out why sometimes I was getting the patch color in areas that ware white in my bitmap (and I am not even talking cookecut here). Incidentally, when I used the same image as a Cookiecut — the white areas started to make holes in my patch… So here was my "background color" mentioned in manual. The funny thing is that it is not necessarily always white… Nor it is the background color of my segment (I sometimes use black as cookecut color). There are also number of problems. Try to put some Mirror and higher Ambiance values on your cookecut with a reflective object behind… It will reflect ambiance of cookiecut areas… Another thing; in Playmation 1.48, 8-bit PCX file were enough for image mapping. Ever since I upgraded to A:M (Win v.2.06 now) the 8-bit files with custom palettes, both PCX and TGA, give me "psychedelic" colors on my renders. (My theory is that they use the "standard" window's 8-bit palette instead, but I didn't really go to check it out). To make it right I need to convert it to 24-bit which take much more disk and memory space for the same resolution (if you have less than 256-colors in your image map).
