The scene is really simple it's three planes each with a variant of the material now each material is a "light" in itself as it's a blend between null and emissive phong. Now my problem is that it says my scene must contain a light source even though there are three of them present
P.S: Before you ask yes environment is set to "None (lit by mesh emitters)"
P.P.S: The name of the blender material also matches the name of the blend material inside the .igm
