Blendable array after modification

Hi,

I’m working with a blueprint that has a PostProcessVolume. In this blueprint I use to change some values of a post process material created and used into the blendable array. I noticed that if I don’t set the material back into the post process volume it does not effect at all the scene and it loop as it is suppose to. But if I do set the material, into the post process volume, it just modify it one time only.

Am I setting the material back wrongly?

RESOLVED.

I’ve created one time only the dynamic material instance and did cycled in it and on each cycle I’ve updated the post-process blendable material.
