Welcome to TVPaint Community forums !

Hey!
Regarding usual work and scripting, I hate that layer opacity (or tv_layerdensity) isn't undoable. It wasn't like that before and I don't understand why it has been changed.
It means that we can't interact with layer opacity without kind of remembering what it was before with a script, we lose lots of possibilies because of that and we can't really "try and undo" to find the best opacity

Yea, that's something which bothered me too.

Hmm, I agree that it's annoying.
We'll see what we can do. It likely won't be for 11.5.3, but probably for the one after that.

Thanks

Some users prefer not to have it, so I assume there will have to be another preference setting ...

:'( argh ok
What's the reason for them, out of curiosity?

Problem with letting people choose is that it may mess up with the scripts, I think scripted opacity changes should always be in the undo stack and it's only cursor change that could be an option
