Here is a simplification of my problem:

I have two side-by-side volumes, and one of them has voxels that are twice the size of the other's. Or, another way of wording it – I have two volumes that are the same size, with resolutions e.g. 10x10x10 and 20x20x20.

When I render the image, there is a seam between the two volumes. This seam is not there if the two volumes were have the same voxel size.

How do I remove this seam? Is there something I can do in the shader?

Use a VDB combine sop > You can resample the incoming volumes ie A match B etc.
