How do I reduce CPU render time?

13 Ways to Reduce Your Render Times

1. Turn off Ray Tracing. If you didn’t know this already, ray tracing eats CPUs for breakfast.
2. Lower the SubSurf levels.
3. Turn off soft shadows.
4. Turn off Ambient Occlusion.
5. Turn on Simplification.
6. Turn off blurry reflections.
7. Turn off Subsurface Scattering.
8. Turn off shadows.

How to set the render time in Iray?

If you have older or lesser hardware, you need to set the time much higher to get the same samples. Rendering Quality Enable: If this is set to OFF, Iray will just use the Max Samples and Max Time to determine when render stops. If you want render time to go just based on those, turn this to OFF.

What are the render settings in Blender a cycles?

You can find it here: The samples are the most well-known setting in Cycles. They are labeled render and viewport. The render count is used for the final renders and the viewport samples are used in rendered viewport shading mode. You can read up on all viewport shader options and what they do in my guide here:

When to use adaptive sampling in Blender 2.83?

Adaptive sampling appeared in version 2.83. The idea is that Blender will sense when the noise is reduced enough and therefore stop rendering the area while continue render areas that require more samples to become noise free. According to the 2.83 release notes render times are reduced by 10-30 percent when using adaptive sampling.

How many samples should I use in Blender?

But as a rule, if your scene is setup correctly, it is my opinion that you should not need to go above 1000 samples. But there are artists that think even one thousand is a way too high number. At the lower end, I rarely use less than 200 samples. But then again, I don’t render many animations.
