Allow the composition author to provide a custom Layer (or a group of Layers) for each component of each UI widget, to completely customize the visual appearance of UI widgets.
Proposed new nodes:
Make Action Button Theme (Layers) with the following Layer inputs:
Make Toggle Button Theme (Layers) with the following Layer inputs:
Checkbox: Toggled and Hovered
Make Slider Theme (Layers) with the following Layer inputs:
Active Track: Hovered
Inactive Track: Hovered
You could then create your own Layers (using Vuo's built-in Layer nodes, or using custom images) to feed in to these nodes, and the UI widgets would display the appropriate Layer(s) at the appropriate times.
Wanted to know if there is a reason why something like Karl Henkel both his "3D Object to Layer" and "Layer to 3D Object" nodes are not included in the stock nodes ?
Using it quite often to bypass some limitations (Use Copy 3D Object with Material with layers), having scene based compositions not having to select different Z-axis to blend nicely etc.
Once "Allow custom node paths" will be implemented it won't be really a problem anymore, but until then, it's sometimes complicated to share compositions with custom nodes.
