Title: Exclude from motion blur
Post by: Otuama on 2023-09-10, 11:04:53

Hi all.

I have geometry motion blur turned on in my camera.  However I have a spherical star map (on a sphere)  linked to my animated sun which when shows up during the night time phase - the sphere rotates with the sun.

I'm doing an animated day cycle across 1000 frames and this means the stars are getting motion blur, which is correct but I want to either reduce the effect or turn it off.

Any ideas?

I can always render the background on a separate pass but I'd ideally like to keep it all in 1 render.

Thanks

Motion blur can't be controlled per object in Corona, you can only adjust it globally in camera, or in render setup.

Ok, thanks.

Looking at a basic test I did last night, the Corona clouds don't seem to be affected by motion blur, which is good in my case because to get around the star MB I can turn it off and render the sky & stars on a separate pass.
