About Redshift - Volumetric Scattering And Fog rendering time

Post by Sung.tw » 25 Oct 2018, 06:33

I recently used Volumetric Scattering And Fog rendering in Redshift rendering but the rendering time as long as a few hours. Finally, I try to lower some parameters ,but it still takes 1-2 hours.

Is there a way to render in a few minutes?

For example 20-30 minutes.

Please, thank you.

what are these? instanced lights? mesh lights? you are using incandescence material?, what gpu you use?
this would probably take 5 minutes on my 2x1080 cards. so something is def wrong.

Hi

Maximus Thank you for your reply.

I used the Mesh in Redshift PhysicalLight to specify how the model turns into a light.

My gpu is 1x1060. Does the error mean the model in the scene or what?...?

thank you

dont use mesh lights, create an area light with a disc shape for each light and your render speed should be 10x faster.

Mesh light isnt really recommended for this scenario at all.

can you share the scene i'll take a look?

Hi,Maximus.

Sorry,I reply so late.

This scene is not my personal, so I can't provide it to you.

But I will try to change the type of the light back to the general test.

Sorry, and thank you so much for your help!
