Middle texture floating in air?

[Sonikkumania]

So recently I've spotted a bug in one map I've made. There's a fence texture that's meant to remain on floor. On map editor UDB it looks as it's meant to be:

However this is how it looks ingame, latest GZDoom being the source port:

So what exactly is wrong? I remember it was functioning as intended before, so this problem has risen out of the blue. Here's some details I doubt might be related to this issue:

1. I downloaded the latest GZDoom not too long ago, maybe one to two weeks. I forgot to save my settings from the previous version so I had default option settings on with new GZDoom. So could this be related to some display and video options?

2. Previously this map was in .wad format but around same time as section 1. happened I compiled a .pk3 directory of this mapset and other resources featured. Could this have "corrupted" the map in some way? (Propably not imo)

3. The map featured here was made in Doom Builder 2 but recently I've moved to Ultimate Doom Builder. Would that be a problem?

 

Any advice would be appreciated though if I can't figure this out I'll just propably remove the texture completely. Would be nice to know what causes the problem though.

In the mean time I'll try to keep changing the options in GZDoom ...

Have you checked whether the sidedefs have accidentally been given a Y offset? It should be 0, and with the "lower unpeg" flag checked.

You could try something like this with 3dmidtexture (Walkable middle texture) and offsets:

Thank you, it seems to be working now. Y offsets were 0 but flag was unchecked .. Which makes me wonder how was the texture offset correct earlier when I had defined it manually? From now on I'll double check the LU flag, lol.

Thanks, I was thinking about this sometime ago. Very neat!
