hi everyone, here is a little tool i made to create custom curves in after effects.
i made it cause i found that it can be pretty long to create complex external curves in UE (or maybe i m doing it the wrong way :)), and there are a lot of tools missing to manage keyframes (scaling …).
so i made a script to export a keyframe track to a csv file, to import in UE.
tutorial here : TUTORIAL : export a curve from after effects to Unreal Engine - YouTube (sorry for the sound quality…)
and the script can be found here : http://expose-pictures.fr/unrealengine/curveexporterv2.zip
if you find any bugs, just tel me, it should work with any version of AE since CS6 (be sure your after effect is in english to avoid bugs … always the same things with that script engine 
)
