I awas just doing a PlayRaw when I encountered a problem with drawn masks in darktable 3.0
My expectation is that the mask delivers 100% blending inside and 0% outside.
But what I get is this:
I found out that I get the expected behavior when I remove my database, the folder ~user/.config/darktable
But I would like to stick to my database and only correct the behavior of the mask.
Does anybody has an idea how to do that?
I think this is to do with the mask shape retaining some default opacity from a previous shape(?). I have this all the time with darktable 3. Hold the control key down and scroll while your mouse is over the shape. This should alter the opacity.
I still haven’t worked out how to get it to retain that opacity for the next shape though.
your tip with the control key + scrolling the mouse wheel works
So I can manage it for now, but unfortunately there is still something screwed up.
The next mask starts again with less than 100% opacity…
Well, maybe I should wait for the "self-healing
I have a perhaps (?) similar problem.
In most of the tools I tried my drawn AND drawn¶metric masks simply don’t work.
(Parametric masks are OK!)
I try extreme values, different color spaces, different blend modes…
The selected area does not change.
The rest of the image also remains the same as if the module has not been activated.
Just an example (the problem is not limited to this module):
You are not alone, I have the same issue also.
Check the $HOME/.config/darktable/darktablrc entry “plugins/darkroom/masks/opacity”
When I encounter strange behaviour of the masks, that opacity value is below 1.
Unfortunately I don’t have a clue when and why that value changes…
Change the value to one and the masks work as usual, till…
Unfortunately, that was the first thing I did after reading this thread. It did not work.
By the way, my retouch module also behaves erratically…
I suspect all these may turn out to be something I did unknowingly… I have no idea.
I am thinking of re-installing darktable.
You’ve tried ctrl-scroll to change it as well? My recollection is that the opacity slider in your screenshot is the opacity applied to the blend. The shape’s opacity is controlled with ctrl-scroll.
And if you’re changing darktablerc file, make sure you’re out of darktable when you do it.
Chris’s reply helped already.
I did not mess with the config files except for the mask opacity setting.
Still, I note your suggestion for future problems (due mostly to my ignorance, by the way).
I had this happen to me on one of the 3.0 RCs and just again today. I was in the middle of editing and palced a drawn mask with no problems. A few minutes later, without switching files or exiting to light table, the next drawn mask barely showed. Luckily I knew to use ctrl + mouse wheel but I have no idea how the setting the darktablerc got changed.
