Missing of 'lightmapping'

Hello all! I am absolute beginner and I think I have searched all the keywords.
However I still can’t find the lightmapping function as told from any videos or threads


Can somebody teach me please? thanks you!

Select the “Lighting” item.

and then?

What I expect is to see this one…

Thank you!

That doesn’t exist in Unity 5. Any material concerning lightmapping in Unity 4 isn’t relevant anymore since Unity 5 uses a completely different system.

–Eric

Oh my god… I see, so does it mean Unity 5 expected user to do other things
then I have to download Unity 4 instead, anyway thank you very much!

I wouldn’t recommend downloading Unity 4. Relatively few people use it anymore, and everything is heavily focussed on Unity 5 now.

I see, then I need to find a way to do baking of light in Unity 5 instead of using lightmapping in Unity 4. Eric, do you have any suggestions?

It would be good to start by reading the docs. Unity - Manual: The Lighting window
