Unfortunately, I can’t use time. I need the value to be an accumulation of over time of another input.
What I don’t understand, is that the ‘value’ variable seems to always be set to the initial value at the first rendered frame.
When the expression returns a value, I expected that to be stored for example in the slider and when the next frame is rendered the ‘value’ variable would be the current value of the slider.
