Description
I'm trying to use spot light to cast shadow on invisible plane but can't make it work. I found that directional light can cast shadow on both visible and invisible plane while spot light only shows shadow on visible plane.
directional light + lit plane
directional light + unlit & shaderMultiplier plane
spot light + lit plane
spot light + unlit & shaderMultiplier plane
material of invisible plane
material {
name : shadow,
shadingModel : unlit,
shadowMultiplier : true,
blending : transparent,
transparency : twoPassesOneSide,
}
fragment {
void material(inout MaterialInputs material) {
prepareMaterial(material);
material.baseColor = vec4(0.0, 0.0, 0.0, 0.5);
}
}
