How much memory does your computer have?

I used to get that a whole lot on my older computer with 384MB SD Ram. What I had to do is go into my graphic program and resize all of my texures to 1024 on the longest side, and I used "Bicubic Resampling" so I didn't lose image quality.  I did save the originals to another directory before overwriting them with the new reduced ones though.

When I rendered I also had to change the bucket size to 16 or sometimes even 8.

Also, if that didn't work, then I would have to make parts of the image invisible and render in pieces to assemble in my graphic program.

If you have clothing that covers body parts you can make those body parts invisible below the clothing which will sometimes help with rendering.  Even if the parts aren't seen below the clothing, Poser calculates for those parts which is why making them invisible will sometimes help.

Those are just some of my suggestions.  Perhaps others have some other ones.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
