In an animation I’d like to change some PBR parameters over time.
Is there a way to access the PBR variables inside a programmable filter ? Or would there be another way to do something like this ?

You will not be able to control PBR via a Programmable filter: it is aimed to modify inner dataset, not their rendering parameters.
To modify PBR in an animation, look at the `Python Track` in animation view and do some ParaView python scripting in it.

Hi @nicolas.vuaille ,
Thanks for the reply. Yes indeed, I got a work around creating a python script over the weekend.
So I guess that’s the only solution
