<br>
Would you be able to achieve your idea by using render layers
and layer masks? Render some parts with GPU, others with CPU
then combine the results.<br>
<br>
Just trying to think of helpful workarounds,<br>

Thanks for the reply. I see. Just thought that because the limit
of the VRAM.<br>

Cheers.<br>
