I was just working on a project and happened to notice that the input to the rotation for the instance on pointsInstance on Points in 4.1 is no longer a blue socket as it was previously. It is now purplish in color, although the scaleScale socket is still blue.
I wanted to know what this representedrepresents.
I have attached a picture of the node:
Previously both rotationRotation and scaleScale were blue, as they are vector field inputs. What has changed now? I could not find anything in the manual.
