Is it possible to export a volume or vdb? #715

Wondering if this is possible, thank you.

Wondering about the same question.. My thought is to have a python script automatically sample the volume with proper granularity and store the sparse voxels data structure. Then convert the sparse uncompressed voxel data to VDB data structure to improve the compression ratio and runtime performance. (I am new to volumetric rendering, so please correct me if I am wrong).

I am also wondering this question, too. I want to use generated mesh in Unreal Engine but results are note good or at least not as good as Nerf's GUI. So, if we can get .vdb export we can use it with UE5's vdb plugin.
