Amazingly there's no apparent way to change layer hue! To change the colour of a layer (ie a copied layer) seems like we have to convert it all to an "image".
I see there's another request for change layer opacity, so I suggest combining all of these functions into one node, or set of nodes.
Would it be possible to add phase and period controls to the gradient image generators to make repeating and animated patterns? For example, give a Make Linear Gradient Image 3 colours but then give it a small period to repeat the 3 colours over and over. Phase would then let you animate the gradient over time with options similar to the Change Wrap Mode node such as mirror, hold, repeat etc.
It would also be great to have interpolation method control between the colours in order to make hard steps.
A node that generates a 2D mesh that is able to be deformed with smooth curves.
Useful for advanced projection mapping. Vuo is already able to do this using Paul Bourkes mesh deformation software, but a solution that allows custom control within Vuo of each point could be very useful for mapping onto irregular surfaces.
Otherwise possibly a way to generate mesh mapping values from within Vuo for the Mesh Mapping node.
