Description LaTor 2020-11-19 22:10:19 UTC
SUMMARY
In Krita 4.4.1., the Luminosity/Shine (Sai) blending layer mode is not the same as to when the mode first came out in Krita 4.2.4. It creates a dull white, which dulls the design. I have reported this first on the krita-artists.org forum, where tiar looked it over and helped me to report it here, calling it a regression.

STEPS TO REPRODUCE
1. Open the file in Krita 4.4.1.
2. Draw with a 100% white while the layer blending mode is Luminosity/Shine (Sai).
3. The dull effect will appear.
4. Downgrade to Krita 4.2.4
5. Repeat step 2.
6. The original light effect will occur.

OBSERVED RESULT
Matte/dull white effect, which dulls the entire design


EXPECTED RESULT
Light shine effect from previous version, Krita 4.2.4

This is the link to the shared files in a Google Drive folder. "Pineapple Cherry Monkey - 4.2.4." is the .kra file with two Lumiosity/Shine (Sai) layers created in the two versions of Krita.

Layer 59, in the "Eyes" group, is the Luminosity/Shine (Sai) blending mode layer created in Krita 4.2.4, while the layer just under it, named "Highlights", is the Luminosity/Shine (Sai) blending mode layer created in 4.4.1.

I have downloaded the latest version of Krita, Krita 4.4.2, and as I was working on a project, I used the Luminosity/Shine (Sai) blending mode in this version and the light effect works perfectly! Thank you so much Krita developers for fixing this issue and for making this version incredible!
