Anim blueprint inverselerp threadsafe

Anim blueprint reports this:

"Warning Node Blend uses potentially thread-unsafe call Clamped Inverse Lerp . Disable threaded update or use a thread-safe call. Function may need BlueprintThreadSafe metadata adding. "

To me it sounds as this call should be threadsafe?

Hi ,

I don’t know if I’m crazy, but I can’t seem to find a Clamped Inverse Lerp. Is that a custom function in your project?

Agh. My bad… Apparently I assumed this to be an Unreal function… and it was not. UE 4.15 probably added that warning.
