I’ve had the same issue as Crayox. I’m trying to fly a simple flag in my scene with APEX cloth. It blows around just fine, in the specified direction determined by rotating the WindDirectionSource, however, the Strength, Speed and Gust parameters seem to have ZERO effect. I’ve also tried adjusting these parameters in the “cloth” level of the Example Content demo, (even up to values of 9x10^24), and the cloth blows the same as it does at default 0.1.
