Quake Enhanced, Scourge of Armagon - missing texture

[mooreye]

When playing Quake Enhanced, Scourge of Armagon, map hip2m4 the end gate of the level has checkered/missing texture, as seen on the screenshot. My hipnotic's pak0.pak md5sum is a9e2a6e544da7f506f6b65b0661e89a9, I use GOG purchase of Quake Enhanced.

Reproduced with quake enhanced update3, hipnotic pak0.pak is 79,928,584
bytes with md5sum 4dd6bf448c9c3c2615b47e2e20bedb43

Possibly a missing texture - haven't investigated. How does ironwail or
vkquake work? (CC: @andrei-drexler, @Novum)

[sezero]

Same thing happens in vkquake for me

[Novum]

And I assume this does not happen in the Kex Quake?

No, it doesn't seem to happen, although it uses different texture than the retro SoA did:

I'm getting a warning "Mod_LoadTexInfo: 12 textures missing from BSP file". Does not happen with the original hipnotic (non rerelease).

After debugging for like 5 minutes I have no idea how this works in Kex Quake: The texture lump just has invalid (-1) dataofs entries.

[mooreye]

Can anything be done to fix this with an extra pak1.pak or so?

[andrey-budko]

They probably use textures[0] for missed textures.

Huh.. Thanks @andrey-budko. Now, if we had a fool-proof way of detecting rerelease content..

[sezero]

@Novum, @temx, @ericwa, @andrei-drexler: What do you think of this?

[andrey-budko]

I think we can ask @svkaiser

[sezero]

FWIW, I can make a 'detection' (cough..) of remastered content like below.
Combined with @andrey-budko suggestion, it would be like:

no lightmap with TEX_MISSING flag

no lightmap with TEX_MISSING flag

Well, I wasn't expecting any solutions to this thing at all to begin with.

I'm still not sure that your patch whether your patch can cause any
serious side effects either. Ie.: no lightmap would be the least of
issues with replacement textures, no?

[andrey-budko]

Just in case you didn't notice. I'm not sure about my patch too.
