Unfortunately this didn’t work for me as I’d hoped; It filled in the transparent parts of the image with white.
This did work for me though:
shader_type canvas_item; void fragment(){ vec4 c= texture(TEXTURE, UV); c.r=1.0-c.r; c.g=1.0-c.g; c.b=1.0-c.b; COLOR.rgba=c; }Thank you for pointing this out! I’ve updated the code so now it should do what you expect. The new code does pretty much what you do in your example, but a bit more compact.
Great, thank you!
