Why does AUR render blockiness

Hi,
Why does vdb made with phoenix renders edges smoothly but native AUR shows blockiness. Same flame rendered with octane. Thank you

under render panel try change sampler to “spherical”

Hi,

It’s already set to Spherical. Thank you

is this the exact same sim , but one is AUR and one is VDB?
maybe worth putting your file here or sending one to “support”

I’ll attach it later. Yes. The same sim. One output is AUR, the other is VDB.

You can try and change the Storage Quality in the Output rollout settings. Where the range is from 8 to 20 - 8 is the smallest size, while 20 is the best quality and is uncompressed.

wow…didn’t realise storage quality would have that dramatic and affect on it
