<<Now, what I want to know is *WHY* does 3DS, when dithering, INSIST on dithering solid patterns in 8-bit FLICS????>> When rendering your flic set Dither 256 to No and you'll get solid colours(and increased banding). <<I can NEVER use dither on, because it shoots up the size of the file by virtue of its unnecessary dithering! Can somebody answer that one?>> The flic file format is RLE(run length encoded) which means that runs of pixels of the same colour are encoded to compress the file size. This method is best for images that have long runs of pixels that are the same. A completely white image can be really well compressed. But when you use dithering, pixels are varied and changed giving a more random image that RLE can't compress as well, this is why the file sizes are much larger for dithered flics.
