Blender 2.9 vector blur not working in fluid sims

Recently I realised that the vector blur for fluid simulations will not work at all for versions of Blender later than 2.9. I enabled speed vectors for mesh and properly setup the vector blur node and it my liquid isn’t blurred. I couldn’t find a sign of others having the same problem, may someone please help?


Are you using OpenVDB as the cache format by chance? If you are then it’s a known issue:

Yes I was. Thank you so much for your response! Changing it back to UniCache fixed the issue.
