10 Hour + Render time for small scene

Corona Corona for 3ds Max Help Required
1

Hello all,

I’m currently having an issue with one of my scenes, I am getting long render times for a very simple scene that should only take 2 hours to render (currently taking 10 hours +).

I have tried deleting objects from the scene, resetting render settings, re- importing to a new scene, rolling back 3ds max/corona to older versions, rendering on a different pc and I am still getting estimated render times of 10 hours.

I have linked the scene, render stats and my spec below (I can’t see any issue with RAM/CPU when rendering).

Intel (R) Core 7 Xeon(R) Silver 4208 CPU 2,10GHz x2
Radeon Pro WX 5100
128 GB DDR4

I don’t think we will be able to troubleshoot this scene without assets. It doesn’t even have the environment bitmap, so it renders pretty much black.
What I noticed is that you have lots of “fire” atmospheric effects in the 3ds Max “Environment and Effects” window (“8” key). Removing all of them might help.
