when a fix

I think DOOM II was fused with DOOM.

maybe.

It wasn't the DOOM update that broke everything, it was a GMod update. It's still trying to read the same IWAD files everyone already had installed, but it seems like one or more of the methods this addon uses to process and render textures and stuff were changed or removed from GMod ...for some reason.
Hoping this will be fixed. This addon brings me so much joy.

The error is caused by the use of TEXTUREFLAGS_PROCEDURAL when creating the render targets. This was never valid, but Garry's Mod didn't care before. Now it does. I had this set in gmDoom Maps to reflect my desire for a better method of loading textures, and I figure Ghor put it in gmDoom for a similar reason. I've updated my addon to fix it, but that doesn't help too much when it is dependent on gmDoom working. I've messaged Ghor about it, but I don't know when they will see it or get around to fixing it.

Turns out Ghor fixed it yesterday, but something went wrong with the upload. It's working now though.

Are you put the IWAD file?
