Ok now this is a memory problem. Two things will cause this. So i will give both answers PC: if you are on a Win 98 or ME operating system, then Windows will only allot memomry upto a 128 block at a time. With current Poser version, the render still requests one block of memory, and for a high res texture it will need at least 300 mb of ram. So you may have 500 mb of RAM but if on 98 or ME, it can't be put to good use. The answer, upgrade to 2000. MAC: Change your memory allocation settings to Poser minimum 150000k and preferred 250000k. That will fix most problems but you may need to allocate more memory to it. Hope that helps. Betsy
