Issues with volume aovs

[alexander_faesYQWXT]

Hey all,

Like in the title, i have quite some issues with some aovs like volume_opacity, volume_z and cryptomatte. In the IPR, the aovs all look correct and good but in the exr sequence those aovs either dont show or are just completely different/wrong.

Render settings + IPR view:

so the volume_opacity looks good in the IPR, but in Nuke or Fusion, this is what the aov looks like:

also, the volume_z aov is missing.

And for the cryptomatte, in the IPR it shows it shows no volumes in the cryptomatte aovs(which is good) but when i render it out and view the cryptomatte, for some reason the volumes are present in the cryptomatte, making the masks from the cryptomatte occluded by the smoke.

Any way to fix this?

Hey,

I think the solution was to disbale "half precision" so the exr sequence is now float32 instead of float16. But it worked before with float 16 so i dont know why it needs float32 now.
