6-Way lightmap Material colors Help - UE5

Hi there! I’ve been engaged on this topic for the last couple of weeks and i cant get some of the colors of the material right. Im really struggling on how should the colors be multiply and added. I started it following this topic 6-way lightmap WIP and others found on the internet!

For reference, im trying to make the colors just like this: https://www.artstation.com/artwork/14lg83

Im currently using 2 textures. TLR + alpha, BBF + Emissive, for the colors, I’m using the color of the directional light (Atmosphere Sun Light Illuminance on ground), but it just looks weird! What Im i missing here? Blueprint material below! Thanks!!!
