There are ways to make textures repeat, at least in P5, but Poser uses UV mapping (stretching over the object). There is no preferred size, but it is always a good idea to make it a power of 2 (512x512, 1024x1024, 2048x2048, etc), 4096x4096 being a good size for hires textures. IMHO, the best format is a non-lossy format like .bmp or (uncompressed) .tif, but a high-quality .jpg will do just as well. DPI is only relevant for printing. It does not matter at all. It's the pixel size, not DPI, that makes the difference. BYS
