Can we export Light maps out of ut3 map package ?

[wenda]

I've been wanting to tweak the lightmaps in photoshop (fix the contrast/brightness) So I was wondering if it was possible to extract the light maps from the level it self.



The light maps are stored in the level it self ,not in a "upk" package.
I've tried to remove the protection by using the fallowing commands in the "log" :

obj savepackage package="AO_test_a" file="AO_test_a.ut3"

And

obj savepackage package="AO_test_a" file="AO_test_a.upk"

without any success...
I get the following message :



Then when I try to export the light maps it doesn't work (nothing is exported)

Anybody tried exporting the lightmaps out of unrealed ?

obj savepackage file=anyfilename package=Package_Name

Is the actual command. then right click to Export to File. Except iirc that doesn't work (or i was doing it wrong)

Surely you could achieve the same with adjusting lighting or a post process volume?

Thanks for the fast reply , seems like the error message is gone but when I right click then export the texture, there is no texture in the target file.
Its still giving me the same issue. I can duplicate the texture from a package to another custom package but exporting it out of the editor doesn't work
Although, Importing textures to the package seems to work.
I guess that the only way to do this, is to cook the level, then use "UE 3 package viewer" (third party tool) to extract the light maps out of the level then import them back.

I just want to tweak the shadows, using a post processing effect would darken the whole scene. I tried doing it in the editor by adjusting the brightness.And the brightness of the lights can't go below 0.0034 (turns pitch black at 0.0033)
I'm using 128 directional lights to simulate global Illumination and Ambient occlusion instead of using a simple skylight.
