Thanks! Back to good old common sense. The only downside in your method is, that it sucks way too much gpu power, Since the poor Omniverse does not know its playing just an still frame, it thinks its playing video file so it updates every frame and so on. As I told you, I have many video textures in my scene and this method is not the best.
I am surprised I hear it from you, very technical person. My humble opinion is that I am not making the problem complicated, I am just trying to optimise my scene. Everybody understand that developing a single value for the start frame for img seq to play is not overcomplicated.
But its a solution anyways so thank you once again from your help with my strange requests. I promise these will be a lot more coming.
