I'm new to geometry nodes in 3.0 and a bit stuck on understanding how to output data. I've spent a fair bit of time searching this, but perhaps I don't understand the system well enough to find the answers I'm looking for.
What I want to do is fairly simple: I would like to write to the vertex color of a mesh using geometry nodes.
I've been able to write a color to an attribute that I can reference in the material shader graph, but I'm unsure how to write the data to the mesh vertex color attributes.
Here's my best attempt, with no luck.
Is this possible or outside the intended use of the system?
Any help is much appreciated, thanks!
