looking for an hour..

couldn't find a way to change the opacity?
for example I have a sketch, and i want to have it more transparent in the background layer, so that i will less see it when i draw over it.

also, is there a way to automatize the alpha/opacity of a layer, or selection, in the frames?

OK
found the way through transparency mask. and using the HSV adjusment..

if anyone knows of a way to automate the transparency mask for fade in or outs?

Thanks

This might be what you're looking for: https://docs.krita.org/en/reference_man ... 20keyframe

It doesn't use a transparency mask, it's built in to the animation facilities.
