Quote - You think 5 minutes for realistic skin, teeth, and eyes is too long? Without the complex shader, you'd spend HOURS trying to get the same effect with a simpler shader.

Did you try my suggestions for test renders, as outlined in the readme? You really don't need high detail to get the colors and overall lighting right. I can usually do 20 renders leading up to the final. By that time, I know the final results are going to be what I want.

How much RAM do you have? You really should have a gigabyte of RAM to run Poser well. You may be paging a lot sooner than I am. I have no trouble running my texture size at 4K. In fact, I have no trouble rendering 5 copies of Apollo in the same render, each with different parameters. Like this one. If you were using different texture image files to get these different ethnic effects, you'd not be able to load even two figures.

i need 4000 for texture because of my bodysuit. 
i have 1 GB RAM

i will try outline.
