Hey !
If it’s OK, we can continue here, so that my issue(s) can (maybe) help someone else checking this thread.
So, I’ve made a post few days ago here : the goal is to get a well optimized 3D object, for a ThreeJS experience.
I’ve made several tests, and when mixing together the PBR textures and the Lightmap (within the emission shader), I am getting a VERY bright texture. So it appear that my lightmap is wrong.

My current shader :
How bright the scene is (at ,5 factor) :
How I want it to be (but maybe that is not possible and I am going in the wrong direction) :
