I’ve also got the same problem right now. The Turbulence 4.7.6 branch compiled with no errors, the editor launched without a hitch, but the sample maps show emitters with no working turbulence . I tried creating my own level map using the sample assets and a simple emitter from the starter content, but couldn’t get any of the field samplers to work that way either. The only exceptions were the noise and attractor FS modules from within cascade, which worked fine, even though the same field samplers didn’t work when placed directly in the scene via the FieldSamplerActor. I’m new to so may be missing something simple, but so far I’m not seeing those I’ve been salivating over.
