Quote - Well I am quit new to 3D modeling/rendering etc to.

At least save your scene before rendering, I alway's save my work before I do major things like rendering.
Just in case.

I would say, lowering the res on your textures should help.
The less details Poser has to render, the better it go's.

The more things you add, the more Poser and your comp has to work.

I use 3000 x 3000 textures, they are hi res and are not a problem.
Only when I render on Final, it takes a lot of time.

I did read somewhere on the forum that rendering in a separate process seems to reduce render crashes.

okay, would it also reduce the chances of the Blue Screen of Death? lol
