BPR Rendering

Hello all,

So, I’ve been learning Zbrush for about a month now, becoming more and more familiar with it. I’ve come to the time to render out a pretty detailed model, with multiple subtools combined into one. Now, before I rendered out small models under “Best Render” with no issue. But now that it’s more complex, my computer just closes out Zbrush because of a memory issue. Now, I have a 4K Imac with 32GB of Ram, and I do not feel this should be happening. The model only has 5.7 millions polygons, and it seems like about 12, it gets slow. So polys shouldn’t be the problem. I am however rendering at the max document size, as these are for 2D print projects. They have to be large. I’ve tried maxing out the amount of RAM under Pref>Mem, but it makes zero difference.

Can anyone shed some light on this for me? Aren’t the same amount of polygons regardless of document size? Is what I’m asking achievable? I feel like this should not be happening, but maybe I’m just doing something wrong.
