Precisely what are attributes in the context of geometry nodes? I have been able to find little to no documentation and/or community info on this subject. Explaining or linking to an in-depth explanation would be appreciated.
the attributes are to control particles you can use them to change particles scale, rotation, etc...
I have a tutorial you can watch here: https://youtu.be/YudUfp0N2QU
Every point referenced in an object has an attribute, whether that is vertexes or points generated using a point distribute node. An attribute stores a bit of information of every one of these points. This could be a points scale, location or rotation. It could also be a user generated value such as a vertex group. Think of them as variables for every point in an object.
