Hi... I'm trying to figure out how to handle nested LayerShaders mat.InsertShader(gradient_shader, sha_xlayer) inserts gradient_shader as a child of sha_xlayer ? Would sha_xlayer.InsertShader(gradient_shader) do exactly the same thing ? If yes, does mat.InsertShader(sha_xlayer) have to be done first as well, or can you set up a shader tree first and then add it to the material? best, index
