That command actually gave me an 800% speed increase!
It turned out I had to use a very simple line of a code for it to work. Anything complex or potenially dynamic, and the line would disable itself it seemed. I ended up taking single execution pieces of math inside variable output expressions and putting them into slider controls. From there I could use the snippet you gave me and it would execute a single time. Then I could reference the slider in my main code.
This is an interesting find but I don’t seem to get any performance improvement from it.
After it seemingly didn’t work, I decided to test it on an ease function to test if it would cause the ease functions first value to become stale throughout the rest of the timeline and it did not.
