SUMMARY Cannot click the greyscale preview of a mask, just to the left of the mask layer in the Layers docker, to bring up the mask as a greyscale image on the main canvas. STEPS TO REPRODUCE 1. Create a new file. 2. Create a new transparency mask. 3. Click on the BW preview box to the left of the transparency mask in the layers docker. 4. Draw onto the canvas. OBSERVED RESULT The image remains blank. When you mouseover the image preview of the transparency mask, a preview of the scribble shows up. So the mask is taking the drawing, it's just not showing it on the canvas in any capacity. EXPECTED RESULT The transparency mask should show up as a greyscale image in the main canvas window. SOFTWARE/OS VERSIONS Lubuntu 16.04.3 LTS Krita Appimage 4.1.5 ADDITIONAL INFORMATION https://www.youtube.com/watch?v=itW9wfPMyWc In this video from about 3 years ago at around 0:30, the author (apparently) just clicked on the small B&W preview box for a selection mask and it popped up on screen. I'm using the Krita 4.1.5 appimage for Linux and I can't do that. The closest I can get is isolating the layer and painting on it that way, but that's very laggy for me (a known bug that was apparently fixed in 4.2) and rather inconvenient if I want to rapidly switch between the mask and the underlying image. Isolating the layer works as a work-around, but doing so isn't very practical, since sometimes I want to quickly switch between the greyscale mask and the underlying image. (Also, isolating a transparency mask has a really bad lag bug, but that's already been reported and is apparently fixed in 4.2.) Note that a Windows user independently confirmed the same bug with a windows build of 4.1.5 at this url: https://www.reddit.com/r/krita/comments/ajafs2/question_is_it_possible_to_pull_up_a_mask_as_a/?st=jrbasnpb&sh=bfc3ac91
No, the video doesn't show anything to do with transparency masks. It shows the global selection feature. Go to Select/Show Global Selection Mask, then the selection will appear in the layer docker where you can select it and paint on it.
I can't do that either. When I click on the preview for the global selection mask, the exact same problem occurs; I can paint to the mask but not see it in greyscale. I thought they were similar enough to fall under the same bug, but I can setup a separate bug if you think it won't just get closed as duplicate.
I can reproduce this: It seems to be caused in specific by indirect painting again. The color smudge brush which has no indirect painting for example does update immidiately, but pixel brushes with 'wash mode'(which uses indirect painting) don't seem to cause an update of the view. reproduced on Krita Version: 4.2.0-pre-alpha (git c5838c0) Languages: en_US, en_GB, nl Hidpi: false Qt Version (compiled): 5.12.0 Version (loaded): 5.12.0 OS Information Build ABI: x86_64-little_endian-lp64 Build CPU: x86_64 CPU: x86_64 Kernel Type: linux Kernel Version: 4.15.0-46-generic Pretty Productname: KDE neon User Edition 5.15 Product Type: neon Product Version: 18.04
Wolthera confirmed it, so I change the status (also, REOPENED suggest it was fixed once and now the issue appears again; but in this case the report was just closed as NOT A BUG, so 'reopening' just confirms it is in fact a bug).
Hi, Wolthera and Brendan! Could you please share an image and a brush preset (at least name), in which I could reproduce the problem? I cannot get it here :( I tried painting on a transparency mask with a pixel brush in both Wash and BuildUp modes and it seem to work :(
Created attachment 119764 [details] Video showing the problem Video showing the problem with a basic brush. I guess the trick here is isolate mode.
Ah, I should have isolated the node first! Thank you for the video! :)
I'm pretty sure Wolthera is describing a different, albeit probably related bug. My problem is that I cannot view any transparency mask without isolating the layer first. There is nowhere on the node that I can click to bring up the greyscale image that represents the mask, and I'm pretty sure there should be.
According to the guy in this video: https://www.youtube.com/watch?v=hLW6ulXZ9GM in Krita 3.0.1 you could access the mask by holding "alt" and clicking on the thumbnail.
Git commit 0ed30208c97a8374b8c2b0b04f8d51b9b119d83b by Dmitry Kazakov. Committed on 04/05/2019 at 16:53. Pushed by dkazakov into branch 'master'. Implement a projection store for masks (for indirect painting) We have implemented correct painting on masks, but we have never implemented a projection for them. Indeed, for normal rendering process they don't need it. But when a mask is selected in isolated mode, it still needs a projection, so that the use could see the result of the painting.
