It's a shot from gile(s) would look the same in gamestudio. Because the lightmap is baked over the tiled materials with Ventilators plugin, what you see is what you get when you use gile(s) now. You export to .x or .3ds then import into MED, but I've ran into lots of issues with the exporting/importing process because I'm going blender - gile(s) - 3DGS, it's all possible though.
