ALPHAMASK

[1vanK]

LitSolid.glsl

        vec4 diffInput = texture2D(sDiffMap, vTexCoord.xy);
        #ifdef ALPHAMASK
            if (diffInput.a < 0.5)
                discard;
        #endif
        vec4 diffColor = cMatDiffColor * diffInput;

Unlit.glsl

        vec4 diffColor = cMatDiffColor * texture2D(sDiffMap, vTexCoord);
        #ifdef ALPHAMASK
            if (diffColor.a < 0.5)
                discard;
        #endif

if cMatDiffColor.a == 0 then Unlit discard pixels, but LitSolid do not discard

Shouldn't discard to shader without ALPHAMASK define too? Because if cMatDiffColor.a == 0, this means that the object is supposed to be invisible, right? 🤔

Most techniques (Diff.xml for example) do not use alpha pass and objet should be visible even with .a == 0 (if ALPHAMASK is not defined ofc)

discard is not free. And if you have cMatDiffColor.a == 0, you shouldn't draw this object in first place.
