R_TextureNumForName: SKY3 not found

[NaturalTvventy]

I'm trying to convert a map from ZDoom to Boom compatible (it's in Boom format so no issues there). When I try to run the map in PRBoom-plus I get R_TextureNumForName: SKY3 not found.

 

I checked the whole map for SKY3 and none of my sidedefs use it as a texture. I checked what SKY3 looks like in the editor and it looks normal.

I opened up the map in Slade and saw no SKY3 defined in the TEXTURE1 lmp. I checked DOOM2.wad and saw that SKY3 references the patch RSKY3. I checked for RSKY3 patch in my wad and didn't find a lmp for it, nor is it referenced in the patch table. Any clue what's happening here?

 

Thanks!

PrBoom does not support cumulative texture lumps, so you actually do not have SKY3 if that's the case.
