Yeah, any images in Bryce are used uncompressed. So, a .jpg used for a bump map will turn into the size of a .bmp inside of Bryce. It's usually best to try to use a seamless/tile-able image for texture & bump maps, that way you can just scale them up, to increase the texture density, instead of having to use giant images. I usually try to just use 512x512 for maps like that. (texture, bump, diffusion, etc) Sometimes it just has to be bigger, though. AS
