It is wild, I think, that *the only possible way* to export a procedural noise-based volume out of Blender is via PHOTOGRAMMETRY and gaussian splatting.

Like, you literally have to photoscan a nebula. đŸ¤¯

I Photoscanned… a Nebula • Creative Shrimp

Basically I’ve just photoscanned a fully volumetric Blender nebula using 3d Gaussian Splatting.

@gleb indeed gaussian splatting is incredible at rendering light effects ... !
it's also very good with water, grass and leaves, smoke/fog, ... it will change 3D if ... there was some development that permit to use this with lower end hardware and in any circumstance : to use the tech now we depends on those companies to have licensed the rights to use the code commercially, it's not free software ... yet https://github.com/expenses/gaussian-splatting/blob/main/LICENSE.md

@gleb and there is even a #Aframe component to add this to a web page, combine it with 3D text, etc ... and see in #VR #webxr

@gleb wouldn't VDB also do the trick? Based on the video, it should be able to handle that. And Blender has OpenVDB support built-in :)

@victor Victor, as far as I know Blender can't export VDBs out, for procedural shaders.

@gleb this is not the answer but it is a way forward

Also could you potentially export as materialx or something ?

I don't think there is a specific solution yet but being able to export shaders is indeed something that will be pretty important going forward for anything realtime... I would totally throw some money down for a developer or two to come up with ideas.. I suppose we would need a solution for material and geo nodes export?
