I have a procedurally created (and continuously being tweaked) texture in shading tab used for material stuff. I'd like to bring(link) that texture to my geometry nodes tab where I use it to scatter stuff. I previously asked about how to get something from Geometry Nodes to Shading, and it was solved using the empty socket of group output. But now that I want to go the other way, there's not that output socket.
you can do it like this:
Just use the Attribute Sample Texture, then choose your texture and insert "UVMap" (the name of your UVMap) into Mapping and some name (i took dens) and use this e.g. as the density attribute.
NOTE: the Attribute Sample Texture node is a legacy node and is removed in 3.0.0 and later versions.
