Question

Hiiiii . Ummm, I’m facing an issue that makes my enemy (Yeah, I know is pretty ugly )have the lighting is the opposite site where it should be, but just in the main body , the rest is fine .

If I look inside the model the lighting is where it should be outside, so I thought it must be the normals , but looking at the model in Blender it seems to be right .

I could just flip the main boyd’s normals but then I can’t use backface culling .

I tried recalculate the normals and what this topic says but they didn’t work.

Light / shadow acting the wrong way on an imported mesh

Attention Topic was automatically imported from the old Question2Answer platform. Asked By s-traut I’ve recently made a quick scene with some light tests, using GIProbes / directional light and some environment config. And I’ve tried importing different mesh types into that scene, a voxel based one, which works perfectly fine, and another one with a more complex shape, and the shadows/lights looks wrong… It looks like the direction is wr…

These are my import setting if it helps.

Help pls ?

EDIT

I put a normal visualizer to the guy, and its look complently wrong.

This is the shader I used:

shader_type spatial;
render_mode unshaded;

uniform bool WorldSpace = false; // toggle between world and local space
uniform bool RemapRange = false; // remap from -1..1 to 0..1



void fragment()
{
    // World space normal
    vec4 Wn = INV_VIEW_MATRIX * vec4( NORMAL, 0.0 );
    if ( WorldSpace == false ) // Local space normal
    {
        Wn = inverse( MODEL_MATRIX ) * Wn;
    }
    if ( RemapRange == true )
    {
        ALBEDO = ( Wn.rgb + 1.0 )/2.0;
    }
    else
    {
        ALBEDO = Wn.rgb;
    }
}
