Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
This is part of the trees and flowers use case.
We need a mix mode for sure, so users don't have to use multiple Math Attributes. Also to support Subtract.

@SimonThommes Should the output of this always be a color attribute? I just noticed that we have
MixRGB
for shaders, so it's specific to colors. Should it be the same here? Should the node name reflect that?@JacquesLucke Hm, good question.
I feel like it should retain the type of the result attribute. For new attributes, I think, eventually it would be nice to have a dropdown when adding a new attribute within an input. But that's a larger scope todo on the UI side iirc.
For now it's fine to force color attributes (unclamped) for new attribute names, I would say.
This node should have the same viability for vector- and value- as for color-attributes, so I wouldn't change the name.
Alright, thanks. Will do as follows:
More options to control this behavior can be added later.
There is a working version of this node in the
geometry-nodes-mix-attributes
branch, if you want to test it.It's a little bit annoying to use, because you have to prepare so many attributes currently.
On the bright side, this node can also be used for some vector math already.
Will rename to "Attribute Mix" and will add enums to select the input types (attribute/float/vector/color/...).
Will rename the inputs to just "A" and "B".
