So according to PBRLighting I can’t have a Normal scale to manipulate right? also there is no EmissiveColor Multiplier?! if i can set Normal Scale and EmissiveColor mult then how can i do it?
Edit: I guess that Emissive color must be the multiplier right? didn’t notice
I test this on emissive color nothing happened yet still i have no clue on normal scale

 List<Material> friseBeeMat = new ArrayList<>();
        MySpatial.listMaterials(frisebee,friseBeeMat);
        Vector4f emissiveColor = new Vector4f(0.99f,0.19f,0.19f,1f);

        for(Material mat : friseBeeMat){
            if(mat.getName().equals("FaceGaga")){
                mat.setParam("Emissive", VarType.Vector4,emissiveColor);
                //mat.getParam("Roughness").setValue(0);
            }
        }
