Is there a way to get a quick read on what the output RGB value will be of a material + light sources for a point in a render?
Currently I’m trying to create a material and lighting setup to match a rendered yellow plastic to a photographed elment that will be overlayed on top.
I know what the RGB of the highlight, midtone, and shadow on the target photograph are, but currently I’m limited to rendering out the scene (or box-masked portion of a scene) to guess-and-check what the combination of material, node setup, and lighting will produce to try and match the two.
Surely there’s got to be a way to get a point-read of what the final output sRGB .jpeg file will be for an eye-droppered part of a scene, right?
The color wheel widget has an eyedropper, but the final intensity and tint of the color in the render is going to be dependent on other factors like lighting and tonemapping.
If you’re trying to find a way to get this value (as it would be seen when rendering) without any actual rendering, you might be hard-pressed as I don’t think Blender uses any fancy algorithms to do such a thing (at least the color widget code doesn’t).
just a little eyedropper tool you can drop over a 3x3 or 5x5 of 15x15 square of pixels in any viewer and get a realtime RGB read for the final render of just that little section, in the colorspace of your choosing (sRGB, AdobeRGB, etc . . . )
