Byte Sez: I thought tifs mapped smoother and better than jpgs... That what I read on another thread anyways... There is some distortion with JPEGs but not much. The advantage to using JPEG is obvious--shorter download time and smaller files. The advantage of not using JPEG (now that Poser supports GIF files) is that a texture that only requires 8-bit or 4-bit color actually uses less Poser memory than the same texture in JPEG format. The trade-off of using JPEGs is hard-drive space vs. program memory for textures that require 8-bit color or less.
