[SOLVED] light_world.lua incorrect lighting direction

[0x29a]

I'll try it tomorrow again and I'll report back if that was the case

Do you happen to know how to do it? I'd be forever in your debt.

Just use your default window resolution to do this:

Code: Select all

vec4 effect(vec4 color, Image texture, vec2 texture_coords, vec2 pixel_coords) {
  pixel_coords.y = 600.0 - pixel_coords.y;    // <-- Insert this, changing 600.0 to your default height
  float dist = ...

(Edited to make it 600.0 instead of 799.0)

Hi,
actually I tried it out right now. As it turns out, Slime was right!

Code: Select all

 vec3 normal = normalize(vec3(normalColor.r,invert_normal ? 1 - normalColor.g :  normalColor.g, normalColor.b) * 2.0 - 1.0);

swapped with

Code: Select all

 vec3 normal = normalize(vec3(normalColor.r,invert_normal ? normalColor.g :  1 - normalColor.g, normalColor.b) * 2.0 - 1.0);

gets the job done!

Thank you both for your enormous help!

Have a good one
