Thanks @James for the reply.
Yes I use Timeline for my sequence. It’s just not useful when you want the same VFX look on multiple clips because you then need to use different gameobject each time making the workflow really heavy (active-desactivate each of them, when you want to change parameters you have to copy them to all the gameobjects, etc).
Further more, the option to bind a VFX look to a Depthkit on another object (that latter using Shader for example) doesn’t seem to work with more than 2 clips in a sequence Multiple VFX look linked to same video player [SOLVED] - #7 by Julien-RobertLegault
