New Layer's Effects for SAI2
Last year, I came across this thing by accident, and I also accidentally share this secret knowledge:
Paint Tool Sai 2 → Other → Options → Preference → Check the box on "Add 8 special... " — Will add 8 other layer effects from Photoshop 💫
Linear Light/Burn is most useful here, suitable for a layer with a shade in some cases. The rest just work a little differently.
