Hello, I would like to convert the material definitions in a .babylon file to the most basic PBR possible. Currently, exported from Blender, I have two materials; bed.Floor & Bed.Wood: "materials":[ { "name":"bed.Floor", "id":"bed.Floor", "ambient":[ 1, 1, 1 ], "diffuse":[ 1, 1, 1 ], "specular":[ 0, 0, 0 ], "emissive":[ 0
