[SOLVED] Need help in updating frag shader

Newbie_Coder · July 21, 2023, 12:12pm

I’m trying to fix an older project but I really have no experience with shaders/chunks etc
how can I update this piece of code?

    dDiffuseLight = vec3(0.0);
#ifdef CLEARCOAT
    gl_FragColor.rgb = combineColorCC();
#else
    gl_FragColor.rgb = combineColor();
#endif 
    gl_FragColor.rgb += getEmission();
    gl_FragColor.rgb = addFog(gl_FragColor.rgb);
#ifndef HDR
    gl_FragColor.rgb = toneMap(gl_FragColor.rgb);
    gl_FragColor.rgb = gammaCorrectOutput(gl_FragColor.rgb);
#endif

or maybe i can somehow set the chunk API version to use without updating?

Hi @Newbie_Coder,

Most likely that is the endPS shader chunk? If that’s the case, the latest one can be found here:

github.com

playcanvas/engine/blob/main/src/scene/shader-lib/chunks/lit/frag/end.js

export default /* glsl */`
    gl_FragColor.rgb = combineColor(litArgs_albedo, litArgs_sheen_specularity, litArgs_clearcoat_specularity);

    gl_FragColor.rgb += litArgs_emission;
    gl_FragColor.rgb = addFog(gl_FragColor.rgb);

    #ifndef HDR
    gl_FragColor.rgb = toneMap(gl_FragColor.rgb);
    gl_FragColor.rgb = gammaCorrectOutput(gl_FragColor.rgb);
    #endif
`;

Try updating your code to match that.
