density = 0.8<br>shadow_color = green — density = 0.8
shadow_color = green

Examples

local occluded = RenderOutput("/output/occluded") {
    ["file_name"] = "result_tmp.exr",
    ["result"] = "light aov",
    ["light_aov"] = "C[RT]L",
}

local unoccluded = RenderOutput("/output/unoccluded") {
    ["file_name"] = "result_tmp.exr",
    ["result"] = "light aov",
    ["light_aov"] = "unoccluded;C[RT]L",
}

local shadow = ShadowDisplayFilter("/display/shadow") {
    ["occluded"] = occluded,
    ["unoccluded"] = unoccluded,
    ["shadow_color"] = Rgb(0,1,0),
    ["density"] = 0.8
}

    ["file_name"] = "result0.exr",
    ["result"] = "display filter",
