Souper Secret Settings

requires luminance 1.0.1, which does indirectly add some new features to soup

• toggle soup on/off keybind now instead cycles off/world/ui
• soup:noise3d and soup:patchwork now do their noise in uv coordinates when in ui mode
• soup:sepia and soup:voronoi are now slightly more customisable
• soup:crystallize (the actual voronoi shader) now has parameter to use the Nth closest cell, instead of just the first
• flipped direction of motion_blur, so its actually correct
• the default layer that appears when deleting all layers didnt delete properly
• active layer will no longer be left on deleted layers when undoing/redoing
