I thought I'd try to generate a LUT for some ASC CDL values a client is supplying for us and save myself the hassle of writing the LUT generator in python. Are VEX operators not supported by the “Save LUT…” utility?

I get this dialog, which is somewhat mystifying:



Am I doing something wrong?

thanks,

Save LUT only works with color correction nodes which are collapsable pixel operations (gamma, brightness, color correct, color curve, HSV, hue curve,etc). VEX nodes aren't in this category. The node tiles of collapsable pixel operations used to be coloured blue, pre-H9, but it has since stopped working. LUT generation extracts the color correction transfer functions from these nodes, which is why it doesn't work for all nodes.
