[VeuX]

Hello Blender Community !

I’m newbie on this forum
I have a kinf of blur or artefact with the light on my render
Do you know how I could fix this ?

Thanks a lot !

could be a lot of things, do you have animation? motion blur? volumetrics? eevee or cycles?

Hi Jakebane,
Thanks for your help

It’s an animation with geo nodes, and translation on Y axis of my objects.
No motion blur
And just a soft volumetrics, I tried to change the value but I’ve the same problem
The render engine is Eevee

[Jakebane (J Bane)]

then its probably the volumetrics, hard to tell without seeing the actual file

[SterlingRoth]

Eevee volumetrics are always the size of the bounding box of the object, it’s almost certainly that.

Ok. Thanks a lot for the suggestions, guys. Will look into them.
