Volume Slice to Texture

[apollo]

Hi guys,

I'm trying to export color data visualized using a "Volume Slice" node linked to a VDB with different colors inside it, visualization is obviously perfect, but can I export to a texture the stuff I see with the Volume Slice node ? I'm visualizing the Cd attribute....

Tried many ways but I didn't found a simple solution for the moment.

Not sure if this is the best way to do this, but you can use volumesample() to get attributes on a plane. It should be easier to bake this than a volume slice, as you'll have uv.

The plane's rows / columns number will set your texture resolution (1 face = 1 pixel)

Thanks a lot, I'm doing some tests to pick right colors from Volume Cd attribute....

There is a game tool that does it. You can bake/render slice of your volume. It works for any kind of data on your volume.

@BenWall thanks for posting that sample file. How would then go about rendering that?

I'd go with Entagma's method to bake points attributes to a map on UV space:
