Title: Corona 9 extremely long render time
Post by: patr11k on 2022-12-08, 09:45:02

Hello I have some problems..

I start an empty file, create 4 walls, floor, ceiling and 1 window..
I add a corona sky and a sun..
If all the materials are white and the scene is without furniture and detailed objects... such a rendering with a low resolution takes over 1 hour.

Something can't be right?
As I said, I start a new file and used the default settings for the Corona Render, but when I watch some Youtube videos that use the interactive render mode for a detailed scene, it loads much faster...

I use one
AMD Ryzen 9 5900X
64GB Ram
Geforce RTX 3080Ti

What do you mean it takes over 1 hour? In corona the render won't stop unless you terminate it at a satisfactory noise level (under Stats Tab of the VFB). Usually at 3% noise level for Interiors and ~5% for exteriors is fine.

You can also specify the noise level at which the render will stop automatically, under Render Settings -> Scene -> Progressive Rendering Limits.

Hope that helps!
