Is there a way to access/read voxel data like one does with the geometry spreadsheet? I've created some arbitrary data fields that are being advected in a simulation, and then am doing some functions to them after the simulation - but its very difficult to check my progress & debug the whole setup, as there's no way (that I know of) to see if the data is correctly propagating through the field as I expect it to, or if my adjustments are doing what I think they're doing.

Thanks,
Luke

Not directly, but there is plenty of ways to inspect volumes

You can easily attach visualizer to any volume to see it in the viewport

Also you can use Volume Slice as an alternative way to visualizers to see volume slices or also you can have slice represented as points with values to check in spreadsheet

Or also use VDB Visualize Tree to turn active voxels into points with values to inspect in spreadsheet or viewport

You can also use Volume Reduce to quickly check volume ranges

Thank you! That's helpful.
