DescentBB

I'm pretty sure I have no idea what I'm doing here...

Descent 2 has six different PIG palettes and any POG doesn't work right except on the PIG it was made on.
That's probably what's happening here.

I started the map using D1 and the original Descent.PIG, not the custom one. I set D2 to use the custom PIG file. I haven't changed PIGs other than that x.x I'm so lost with this texturing stuff x.x

Eep.
Are the textures messed up in-game too?

I'll check right now when I get home

Normal D2 levels are fine. Idk what I did :/ when I try to switch the D2 PIG in DLE to a normal one, DLE crashes on me x.x

That's happened for me but I never figured out how to fix it. I think Xfing and Pumo know.
You may just have to remember what texture is what while you finish the map and then send it in as it is.

yeah they helped me with it. I just needed to add the Descent.256 file where the PIG was and it fixed it immediately.

For future reference - keep in mind that like AlterFox said, when using pre-made POG files, it's optimal to use only those made with the same palette your level is using. To this end, I've made 7 POG templates meant for starting D1-like levels in D2 version. Those are numbered from 1 to 7 - the first 6 follow the order of the systems in Counterstrike while the seventh is the new one meant to be used with Pumo's D1 palette.
