Just when i thought lightmapping worked again....

Unity Engine

Is lightmapping really screwy atm , cause i have one project, where i have diffuse, bumped, specular on a lightmapped object, in forward render mode, and all the shaders effects work fine. Than in another project, exact same settings, same bake , and yet no bump , no spec shows…

Why is Unity lightmapping so damn hard to use without hinges left and center…

EDITED : AH HAH!

i dunno why , but i have just discovered something. Somehow the lights themselves are marked, because if i delete the light that was used to cook and place another light in the scene , after all the baking , the effects take effect again. Strange behaviour , but alas it works.

Lightmapping simply doesn’t work with bump and spec, unless you use directional lightmaps.

What you get when you delete and recreate the lights is realtime lighting on top of your lightmaps. This sort of defeats the purpose of lightmapping, is very expensive in forward lighting mode, and ends up doubling the intensity of all your lights because they are adding light to the scene twice.

If you switch the inspector to Debug mode … and inspect your lights, you’ll discover this hidden property called “Actually Lightmapped”
