I cannot get any of the FInterp To nodes to function in the slightest. I’ve used them on a project once before in the past and it worked fine. Using the same code, they no longer work. Logically nothing has changed from what I can see. They do not work on a loop or timer either.
Hi, if I get it right then you want to gradually decrease the intensity of your skylight using FInterp.
In your current setup the “Current” value of the FInterps does not change and as “Delta Time” you plug in the length of the frame so it also does not change. So the output of the FInterps will not change (your skylight will stay at a fixed value).
What you need to do is save the “Return Value” of the FInterp into a variable for each FInterp and plug that variable into the Current for the next step. Else you will repeat the same step of interpolation over and over again.
Further you would reset those variable in the respective “BeginOverlap” (there you would set them to 0.45 respectively 5.0).
EDIT: in the image below you can of course also use FInterp To Constant instead of FInterp To
You’re not using it correctly - feed Current light intensity.
fInterp takes a value from Current to Target but every time you call it, it has to start over again since it does not know what the previous value was.
