Invert color :DDD
I know there is like a million of invert color shaders in this.
But all of them suck. (JK)
So here is mine
I hope u like
Shader code
shader_type canvas_item;
uniform sampler2D existing_screen_texture: hint_screen_texture, filter_linear_mipmap;
void fragment() {
vec3 new_color = texture(existing_screen_texture, SCREEN_UV, 0.0).rgb;
new_color = vec3(1.0) - new_color;
COLOR.rgb = new_color;
}
