it might take 20 texmaps at 4096X4096 (64 MB) for poser to fill up RAM to the 1.5 GB limit. unless, of course, poser was rewriting the same textures (redundantly) to different parts of the RAM, which might cause it to max out quicker than one would expect. but then the big problem, since P5 and P6 were introduced, has always been rendering. hence some people don't waste time trying to render in poser. they use some other app that has 21st-century code in it. so it's a big decision for e-frontier. now that there's no white knight on the horizon to purchase and repackage poser, they're stuck with rewriting it from the ground up.
