Decreasing Render Time
show user profile  Justin101
Hi all,

I just recently purchased some awesome plants from archmodels, but the render time is insanely long. The leaves are vray double sided materials with all kinds of translucencey settings and reflections which I believe increase render time by a lot. I removed all translucencey settings, but that only decreased render time by a little bit. Any ideas as to what to check of change in the material settings to decrease the render time? All the plants will be viewed at a distance so all that detail in not necessary. Or is it the two sided vray material that increases render time?

Any thoughts would be appreciated.

Have you tried rendering it with a generic override material?
Is that also very long?

I just adjusted some render settings and it cut the render time in half. I had the irradiance map subdivs at 200 and the Interp. samples at 100. I changed those to 100 and 50 and it cut the render time in half. I had these parameters cranked up to help with smoother shadows.

I took off all reflections, translucencey and bumps on the plant materials and it helped a bit.
Much like with the irradiance map settings, are there any other settings you can think of that I should check so that I dont have things set un-necessarily hight?

Cheers.

Im actually in the process of researching that.
I was gonna get one of the new Ryzens.....possibly the 1800x but am thinking about holding off and waiting for the new 16 core threadripper.

vray 2 sided material, check the back side material, if its got glossy reflections on it. turn reflections off completely. or switch off trance reflections in material options.

keep the front face reflections as they are, just back facing. saves at least 50% render time. (in my experience).

Are they opacity mapped? Set "Opacity mode" to "Clip" under "Options" in the shader, making the opacity map either visible or non-visible. No grayscale inbetween. For still frames this shouldn't be any issue, but for animations, you might encounter flickering.
