Using emmisive textures to light my map

That’s about it then i guess, considering the size of the meshes. Emissive lighting is quite weak and it doesnt generate bounced light so dont expect much from it really. What you can do however, create a tube light in front of that mesh and set that light’s Min. Roughness Value to 1. Now the light source will light the environment while the emissive takes care of reflections.
