Different textures in game compared to Doombuilder

[Mr.Rattlebones]

I wanted to create a tree for my map, so I imported the textures into Slade and added them to TEXTURE1. In Doombuilder they seem fine in visual mode (https://i.imgur.com/iKzU1z3.png) but in game, they seem messed up and different (https://i.imgur.com/IRx75au.png) what is causing this issue?

Know the difference between a texture  and a sprite

Unfortunately you did not mention which format your pwad is in.

TEXTURE1 would indicate vanilla doom format, but who knows ....

 

For vanilla doom you use DEHACKED to replace an existing sprite.

For an advanced port, such as GZDoom, you use DECORATE.

It's GZDOOM and they aren't sprites. That's 8 linedefs in a crisscross pattern.

Nevermind, I only just realised I had the textures under FF_START rather than PP_START
