I'm trying to render a scene in which I have nebulaes made from volumetrics.

EDIT : I forgot to mention that it is a "flythrough" scene, the camera is flying through 4 successive volumetrics cubes. So the camera is in the smoke itself !

I'm rendering with Eevee, and rendering gives me blurry Nebulaes : enter image description here

Could it be a nebulae density problem ? Or is it really an issue with my render settings, and/or camera settings ? As you can see, I also have a particle system here (some kind of asteroïds) and it does not seem to suffer from this blurry effect...

Here's the node setup, the camera settings, and the render settings (with a small amount of samples but even doubling or tripling it doesn't fix the issue) :

Nebulae Node Setup Nebulae Node Setup

Camera settings Camera settings

Eevee Settings Eevee Settings

Sorry for the length of this post, I didn't find any "spoiler" box, and I don't know how I am supposed to resize the images.

  • $\begingroup$ How does it render in Cycles? That might give an indication as to whether it's a problem with your volume or whether it's the Eevee render settings. You could try increasing Samples in the Volumetrics Eevee settings - or if your volume doesn't start until quite a distance into your scene, try increasing the Volumetrics 'Start' until it just starts clipping (and make sure 'End' is no more than the furthest distance of the volume). $\endgroup$ – Rich Sedman Nov 24 '20 at 16:15

    $\begingroup$ Hey @ZargulTheWizard ! As stated earlier, I tried to disable Bloom, it changed nothing :/ I'll give you a blend file, I just need to append those nebulaes to a new file, because my main project will probably be used for commercial purposes. I'll do it in the coming hours And again, thanks for your help ! $\endgroup$ – Pdhm Dec 15 '20 at 16:29

    $\begingroup$ and yeah, in the last image linked, the camera is completely outside of any mesh or volumetrics $\endgroup$ – Pdhm Dec 15 '20 at 16:30
