Hello,
Is there a way to translate a cached aereo simulation within Maya or the Bifrost Graph Editor? I know it is quite easy with polyObjects (as described in this tutorial: https://www.youtube.com/watch?v=_3-bKGZwdbQ&t=671s) but it doesn’t seem to work with aereo simulations.
I am asking, since I cached a huge simulation already, and I would like to reuse it and therefore I have to be able to move and rotate it.
Thank you in advance!

If you store a VDB you can import it with your render engine and move rotate scale it.
Thank you for your reply!
Ok I see. I tried to export a few frame now in VDB and reimporting it with Arnold>Volume. What i dont understand is which properties/channels I have to write/insert into the "Grids" field (AttributeEditor>aiVolumeShape>VolumeAttributes>Grids). Since whatever i choose Arnold keeps rendering the Voxels instead of the Volume_Density. Are there any special settings in the Bifrost Graph file_Cache node i have to consider when exporting with VDB, since until now I used BOB?
Thanks in advance!
Have you assigned the aiStandardVolume Shader and use the Bifrost preset?
Thank you for the reply!
Yes I have applied the aiStandartVolume. I attached a screenshot, so it is easier to have an overview what I am talking about.
Thanks in advance!
Have you turned on use default material in the viewport?
It was not turned on. But even if I turn it on it doesnt change anything. I added a screenshot again.
Thanks in advance!
You need to use the bifrost preset.
There is a preset button on top of the shader tab.
