Re: [18.104.22.168] GZDoom Visual Mode not setting texture offests properly
That had been reported already viewtopic.php?f=8&t=453
So, you are using GZDoom in Hexen format.
There are two remedies:
If you are dead set on using the GZDoom Visual Mode to align textures, then you can use r1416.
If you are dead set on using a later version, eg from r1429 on, then you must
use the UDMF
format for GZDoom Visual Mode to work correctly. In the latest version r1486 you also have the
bonus of floor and ceiling alignment options.
However, if you are still dead set on using GZDoom in Hexen format, then there is also the regular
Visual Mode which works for aligning textures.
