Questions

Hey there,
Im using diffuseTexture on standard material for texture and when i add texture then mesh will have black color background and i tried Fragment_Custom_Alpha but its not working.
By the way i’m implementing in React App.

Welcome aboard!

Is your material an instance of CustomMaterial and not StandardMaterial?

If you can make a repro in the Playground it will be easier to help you.

Hi @Evgeni_Popov , Thanks for response.

It works fine in pg but in React app, not able to achive same output, This is source code i have in React app.

     var mat = new BABYLON.CustomMaterial("mat", scene);
    mat.diffuseTexture = new BABYLON.Texture(textureImage, scene, false, false);
    materialedMeshes.forEach(mesh => mesh.material = mat);
    mat.emissiveColor = new BABYLON.Color3(1, 1, 1);
    
    // mat.diffuseColor = new BABYLON.Color3(1, 0, 1);
    // mat.specularColor = new BABYLON.Color3(0.5, 0.6, 0.87);
    // mat.emissiveColor = new BABYLON.Color3(1, 1, 1);
    // mat.ambientColor = new BABYLON.Color3(0.23, 0.98, 0.53);

    mat.diffuseTexture.uOffset = -0.1000;
    mat.diffuseTexture.vOffset = -1.1800;
    mat.diffuseTexture.uScale = 1.2200;
    mat.diffuseTexture.vScale = 2.2200;
    mat.diffuseTexture.uAng = Math.PI;
    mat.diffuseTexture.wrapU = BABYLON.Constants.TEXTURE_CLAMP_ADDRESSMODE;
    mat.diffuseTexture.wrapV = BABYLON.Constants.TEXTURE_CLAMP_ADDRESSMODE;
    mat.Fragment_Custom_Alpha(`
    if (baseColor.r == 0. && baseColor.g == 0. && baseColor.b == 0.) {
        baseColor.rgb = vec3(0.85, 0.85, 0.85);
    }
    baseColor.rgb = mix(vec3(0.85, 0.85, 0.85), baseColor.rgb, baseColor.a);
`);

@NinjaGamer Try with this. Im not sure how it should be used in React but in pg it works.

mat.Fragment_Custom_Diffuse(`
     vec2 updatedUV = vDiffuseUV + uvOffset;
         if (updatedUV.x < 0.0 || updatedUV.x > 1.0 || updatedUV.y < 0.0 || updatedUV.y > 1.0) {
             baseColor.rgb = vec3(0.25, 0.85, 0.75);
         }        
     `);
