Color a Greyscale image with WebGL?

Is it possible to use a WebGL, or any other effect, to color a Grayscale image inside Construct on runtime?

Yes, try using the Tint shader.

Found it, thank you!

I tried to make a smooth coloring transition

Every Tick

Set LayerEffect(Tint) Paramater 0 to X+1

But it only sets it to X+1 once, when the layout starts, rather than increasing X by 1 every tick. Is that intended?

If X does not change, then neither will the parameter.
