scatter result looks nice and right in fire but wrong when in render view
the objects distrubited like particles in the volume !

Would you send the scene with the problem?

The bad render is on CPU or GPU?

Cpu, i don't use gpu. You can test the scene
Is gpu support scatter ?

Ok, now it works fine on CPU (I think the fix is included on 4.0.0.7), but it gets frozen on GPU. Scatter should be supported on GPU, but I'm going to report this scene to check it further. Thank you.

Thanks
With other simple scene using included objects ( two spheres ) scatter worked fine

I can confirm it works if I put the density parameter from 400 to 100 on GPU. It seems to be a memory problem in this case. Should be better after the memory optimization that is on the roadmap.
