We could build an OSL script for this, and maybe later bake it into the core if enough want this built in.

Done - will ship as a built in node.

thanks, it is necessary to integrate into the octane

How to make opacity with this OSL?

I had a quick look at this. The original script was for 3ds max and has 2 outputs (1 color and the other float)
https://github.com/ADN-DevTech/3dsMax-O ... lorKey.osl

In Octane, we can only have 1 output per OSL node, and it only supports a "color" output.

You would need to use 2 OSL nodes. eg make 2 copies of the script and modify 1 to use the "Col" color output, and the other to use the "Key" float (converted to color).


EDIT: Here is a sample orbx with 2 OSL scripts. I don't know how this is meant to work, but here is a screenshot of 2 planes. You can see through the top one which uses the key as opacity

It would be nice if Octane OSL could be updated in the future to allow multiple outputs (as well as different output types like float/int etc)

It would make nodes like this much easier to create (no need for multiple edited copies)

Yup
