I just committed the new volume object to 2.83, for rendering OpenVDB volumes. This is a topic for user feedback on that functionality.
The main limitations are these, which we are aware of and working on:
- No sparse grid rendering yet in Cycles and Eevee, so uses more memory than it could.
- Loading big volume datasets in solid display mode can be problematic. We intend to add a way to load them at lower resolution (by default when above a certain resolution?).
- Selection in the viewport is only possible with the center point or wireframe.
For more details and future plans see the task T73201.
