Numerical values of RGB Pixel

Flame Flame Questions

Hi there.
Hope everyone is fine.

I was wondering if there is a way to get the numerical values for R, G and B for a given pixel so I could feed these values into an expression?

thx

There is no interactive method, unfortunately. You can use Y_Sample to sample the color, separate it into RGB channels, use each as a displacement map on a white frame and track the height of each thus giving you three values that are baked in. Really convolutedā€¦ and not interactive.

Thx Sinan. Thx for your trick.
Will be a little to complex for my use.
I think there might be a way though as for exemple, the ā€œChipā€ matchbox can tell the rgb value of a selected pixel.
The problem is that the values are showed but not usable. :frowning:

Iā€™ll keep digging :wink:

Yep, not possible to sample the value directly (would be cool if there was an expression). I think in the past there was a ā€˜sparkā€™ that could analyze pixels if Iā€™m not mistaken. I think it was part of Ls_scoops.spark.
But this doesnā€™t work in recent flame releases.
