Hi Brian, very happy to hear SER is being implemented(I'm running 2x4090). Hopefully we see it in dailies/production of 20.0.x, fingers crossed.

Njordy, TOPs is great for that. File pattern to recursively find all .exr textures, then generic generator to run command line job for the conversion. I used maketx, but you can use imaketx or iconvert from the Houdini bin folder too. The last thing to do is to point the materials to new tx instead of exr by editing the usda files. Again you can do that with file pattern to load the files, and edit the string inside with python TOP, replacing .exr with .tx

You can play with the anisotropy on the volume and uncheck Render light geometry, here`s quick setup:
