It would be really cool if the Ruler tool, or similar, could work in 2D previews, and sample the scalar value. For example, what is the default scalar range of the Voronoi Diff Scalar? Or the Perlin 3D Scalar? It would be cool to be able to sample this and other scalars.
Additionally, this information for these scalars would be nice information for the wiki. Like right now I want to do a precise soft maximum and minimum scalars on voronoi diff but it's hard to tell what is the "ceiling" of the scalar by visually seeing where the scalar is unaffected by values.
If this is too crazy to add to the GUI maybe something simpler, like a debug function which takes a input, and just spits out the minimum and maximum scalar range in text when the shader is open.
Yeah this is something I desire too from time to time... I think a "highlight warning" type of GUI presentation where one can set a certain value as threshold for the highlight warning. For example, any scalar >1 appears red.
That would be really handy too, the highlight feature. Yes, definitely would love that.
Actually, highlight warning can be made using a conditional shader and configure to have the if result being red when input >1. Fairly easy, but cumbersome to set up/import clip each time. Also, anything in blue nodes can be made in C++ and runs faster.
