Hi.

I was doing some tests, and was curious if my conclusion here is correct...That poly counts affect render time more than texture sizes by a fair margin, but texture sizes affect memory usage far more than poly counts.

That sounds right...
More poly's mean more time spent calculating ray intersections with geometry.
Textures are quite VRAM intensive. Especially HDR ones.

Thanks
Chris.

Thanks, Chris. It never dawned on me that the poly counts were SO much more labor intensive than the textures...I wanted a render to concentrate on some particular parts so I dumped all the textures on all the others. For a reduction of textures of maybe 70%, I only saw a render speed improvement of about 11%. Live and learn! :)
