Exporting special effects/materials from blender

I’m trying to export some blender mesh with materials set to “emission” and its not working. I’ve looked around, but everything seems to be telling me that theres literally no way and that I’d have to do that RGB overflow glitch thing (where you set RGB values above 255). Is this possible at all (I saw something about baking the lighting or something, but I couldn’t figure out how that’d work)

heres the model btw


(I also have an outline effect achieved using “solidify” and an emission material. It doesn’t seem to work either, and I dont think I’ve even seen any methods to recreate it in roblox. How’d I do that?)
