Twisted_Symmetry, Gotta watch your eyes. I used to get afterimages after being on the computer too long. I've learned to take breaks wevery hour or two, where you get up, exercise or just stretch, look at other things for a few minutes then get bach to it. First make sure you are using the uPDATE version of the tif2pgm converter (t2p9). Secondly what program did you make the tiff in? version? non-Photoshop/Corel Photopaint generated files might not work right. Next: try using 512x512 or 1024x1024 as the size of the image in your paint program. This is a problem within Bryce from what I understand - If the image is nonsquare or not an exponet of 2(256,512,1024,2048 etc) you will get an offset such as you describe. Finally: to get rid of the "base" you will need to clip the bottom in bryces terrain editor until the "base" just shows up as red. If you don't know how to clip terrains in the editor, Aldaron posted a tut a while ago on hoodooies(sp) which describes how to do this along with other neat stuffYou should find a thread about it by searching this forum under the keyword Aldaron(recommended reading). If you are having difficulty getting the "base" to go away without clipping the rest of the image using 8 bit tiffs, try reducing TNC to about 8000(you lose some resolution that way but you should be able to clip it). leave the other options alone until you get used to the program - mostly they're for people to mess around with to alter the image height/scale once thy're used to the program; right now TNC(total number of colors) should be the only one you need to mess with and then only if you can't get rid of the base in Bryce terrain editor (this could also be edited manually in the pgm file (TNC is merely a convienience). You might also try altering the height(y size) in Bryce attributes to get clipping to work. - TJ
