How to properly slice a volume for dds file format
I work at a Planetarium that uses a rendering software called Digistar to project onto a dome. I want to make my own volumetrics for this using blender. Unfortunately Digistar uses dds files for rendering volumetrics which notoriously has zero support for in Blender. I came up with a technique using geometry nodes to "slice" my volume and render each slice as a png image. Using texassemble I can compile all of the pngs into a single dds volume which I can import into Digistar.
My problem is, although the shape of the volume is maintained, I lose all of the detail added by the density of the volume, as slicing it obviously decreases the total volume. Also this method only works for volumes contained by a cube. So, I was wondering if there was a better way to slice volumes like this while still keeping the density detail.
