RE: "Why can't we put 255 as maximum in the matrix value send?"
Well, I was just trying to keep the percentage metaphor throughout the program, and the Matrix Value Send therefore had the range of 0 to 100.
You if you create a "converter" User Actor with this inside you can get what you need:
You can input 0 to 255 and it will convert it to the correct percentage. I looked at the output of the Matrix Value Send, and the hex values it was producing matched the inputs values. (I didn't test every number.... but like two dozen values.)
For the moment, that would be the immediate workaround.
Best Wishes,
