I am using deferred rendering

#

this is the output of my other images

#

This is the pixel shader


@Vertex {
    layout(location = 0) out float2 oUV;


    void main(){
        float2 normPt1 = float2(-1.0);
        float2 normPt2 = float2(1.0);
        float2 size = normPt2 - normPt1;
        float2 midpoint = normPt1 + (size / 2.0);

        // float2 vertex[] = { float2(-0.5),float2(0.5,-0.5),float2(0.5),float2(-0.5),float2(0.5),float2(-0.5,0.5) };
        float2 vertex[] = { float2(-0.5), float2(0.5, -0.5), float2(0.5), float2(-0.5), float2(0.5), float2(-0.5, 0.5) };

        gl_Position = float4(midpoint + (size * vertex[gl_VertexIndex]), 0, 1);

        // gl_Position = float4(vertex, 0.0, 1.0);

        oUV = vertex[gl_VertexIndex] + 0.5;
    }
}

@Fragment {
    #include "pbr.ash"

    layout(set = 1, binding = 0) uniform sampler2D TColor;
    layout(set = 1, binding = 1) uniform sampler2D TLocation;
    layout(set = 1, binding = 2) uniform sampler2D TNormal;
    layout(set = 1, binding = 3) uniform sampler2D TRoughMetallicSpecular;
    layout(set = 1, binding = 5) uniform sampler2D TEmissive;

    layout(location = 0) in float2 iUV;
    layout(location = 0) out float4 oColor;
    //float4 computePixelColor(float3 sceneLocation,float3 color,float3 normal,float roughness,float metallic,float3 emissive)

    void main(){

        float4 color = texture(TColor, iUV);
        

        if(color.w < 0.5){
            discard;
        }

        float3 sceneLocation = texture(TLocation, iUV).xyz;
        float3 normal = texture(TNormal, iUV).xyz;
        float3 roughMetallicSpecular = texture(TRoughMetallicSpecular, iUV).xyz;
        float3 emissive = texture(TEmissive, iUV).xyz;
        oColor = computePixelColor(sceneLocation,color.xyz,normal,float3(1.0,0.0,0.1),emissive);
       // oColor = computePixelColor(sceneLocation,color.xyz,normal,roughMetallicSpecular,emissive);
    }
}

for non vulkan specific questions we usually point people to the graphics programming server as there are more people that can help you with these kinds of things

my bad

thanks

If you're using Vulkan it's okay to ask such questions here. In case it hasn't been answered: What is the actual problem?

#

the original issue was something like I can't get pbr to work on my c# project but it works fine on the c++ project (even though the c++ project has renderdoc issues)

#

but now I realize that they are both broken and I just can't get prb to work

#

I suspect it's an issue with normals

#

This is what I currently have as output
