I have a CParticleSamplerCurve 4D working in PopcornFX Editor to change my particle colors over time.
I'd like to make that curve dynamic in Unreal 4.15 via a PopcornFXAttributeSamplerCurveActor.
I added one to my scene, child of the PopcornFX emitter. I set up the actor to be in Float4 dimension, no double curve, with a link to an Unreal Color Curve.
I manage to assign it to the curve field on the emitter (reference or name) but it does nothing (curve set to full red) at all as if the sampler was not working. I also tried in a blueprint via a name reference and it does not work either, I get a log saying that it's unable to find the sampler whereas it's there.
Can you confirm that 4D curve samplers are working on your side in Unreal 4.15 ? If so, how is it supposed to be setup ?
