A clear and concise description of what the bug is.

Brightmaps do not load when playing any of the ID Software IWADS. Freedoom based iwads load them correctly.

It occurs on 4.12.2 and newer. It works correctly on 4.11.3 so the regression occured between those builds.

Steps to reproduce the behaviour.

Explain how to reproduce

1. Start a game using a DOOM, DOOM2, TNT or PLUTONIA IWAD
2. Brightmaps will not be working.

Works fine for me. Are you sure you haven't switched them off in the launcher window?

Yes the button is checked and the brightmaps.pk3 is loaded. The issue is the game does not make use of these bright maps. I suspect something is messed up with the iwad filtering for applying the gldefs etc.

I suspect it is this commit that broke it.

Just like Graf, it works for me, too. (Screenshot taken using 4.12.2)

Can you test it with this pk3.

I believe the issue may be with wads that use the old legacy filter names like doom.doom2 instead of doom.id.doom2

[blackhand1001]

Yup that's that was it broken. I edited that pk3 to use the new lump filter names and it works now. The old names are broken in the current builds so old mods that use the old filters will be broken.
