Grainy volumetric shadow. Why?

hey.
I was trying to get a volumetric shadow pointing towards the camera, but i get this low res grainy/spotty/dust particle effect where its suppose to be as black as possible.
What is wrong?

Its only a sphere in the way of a direcitonal light. Inside a density volume

 

Did you tried the "Filter" option for the Volumetric Fog?

 

question, what do you mean by "activate both"? Both what?
The performance and cost isnt an issue due to my hardware. And this is just for show, not to be played other then on my pc which can handle the stress.

but thanks for the reply.

sorry, didnt see Fox reply. i will try both suggestions.
Thanx guys

 

Is that in edit>preference>graphics?

 

It's in the Fog component of your game Object with the Global Volume or Sky and Fog Volume.

 

Roger roger.
Thanx

 

I used both of youre suggestions and it worked out perfectly. The grainy particle thing is gone, but there is a slight cloudy shadow now, but its so vauge you can hardly see it.
Thanx guys.

edit:
this also helped me with some jagged borders of my spotlight.
thanx Fox

 

And in case anyone has trouble finding the "Filter" property on the Fog override, note that you need to click the little "More Options" button first:

 

Hey guys, sorry for reviving this topic, but it was the only place I found were people were talking about an issue similar to what I'm having.

I'm using Local Volumetric Fog to build a "Hevenly Sky Scene", and the shadows are very weird and grainy:



I've tried everything you guys mentioned here in ths thread, did not fix it. Anyone has more info on it?

 

Camera dithering on

 

That's because you don't have enough sample count. Also, using volumetric fog to create large cloud is not a very good idea.
