Thank you, Clément. I understand your point.
Congratulations for the outstanding achievements so far.

> HI Adriano,

> Lightmap support in eevee is not trivial. If you just want to bake the
> irradiance (diffuse) in cycles and use it in eevee you can add an emission
> node with the lightmap multiplied by the diffuse color, and  set the
> diffuse color in other bsdf nodes to black.
>
> And creating really good lightmaps system is not easy. We would need to
> encode the lighting directionallity and I don't even know if cycles can do
> that. Also managing instances UV offsets/scalling/packing is another
> problem.
>
> It's not in our short term goals for sure.
