Arnold 6 's much slower than Arnold 5 and wrong volume shading

1. In my simple test, new Arnold is much slower on loading scene than previous version, 14s vs 2m10s. It's even much more slower in large scene.

2. When I render with 2 or more volume, the shader is wrong and appearing mosaic grid.

Link of the scene : https://drive.google.com/file/d/1JT4XFkxky9E4fxkA_hfXbuhvDIHjlk4b/view?usp=sharing


3. In volume vdb file, Velocity channel never work for Motion blur deform displacement , but it's still work with Turbulencefd standard render.

Hope develop team can fix this, thank you so much !

Can you post your Arnold logs for the "slow loading" ?

Can you post the verbose arnold logs from each version so we can see what's going on? The logs will tell us what step is slower.

I think the volume slowdown was fixed in Arnold 6.0.4:

From https://docs.arnoldrenderer.com/display/A5ARP/6.0.4.0 we have this fix:

  • #9595 Slow node update of VDB volumes on Windows and Linux even when volume did not change
