There is a "volume slice"-node that can be set to method > volume. Inside COPs you can import the slice using the "SOP import"-node.

I tried this solution and he sampled the top view satisfactorily, but this doesn't seem to be able to sample values from 1 to 0 outside of volume, I would like to ask how I can get SDF values from 1 to 0 outside of volume, e.g. sampling the SDF from the bottom left of the scene and getting this result.

Thank you, this really helped me a lot

I created a VDB field in Houdini. Now I want to sample the SDF information in this VDB field from the top view and output it into a texture. How can I do this?
