Problem with UVs

Hello,

I’ve encountered an issue and could really use your help.

Over the past few months, I’ve been learning the basics of Blender in order to create modular wall pieces for a student project in Unreal Engine. So far, everything has been going fairly smoothly, but I’ve run into a problem that I’m not quite sure how to solve.

I’m using the “Sure UV Addon” to create good UVs for the walls, as they are one-sided. I don’t need lightmaps.

Everything works good with this base wall, and it’s seamless in Unreal too.

However, whenever I attempt to create different pieces from the original wall by changing their size or adding a hole for a door.

the UVs in Unreal are no longer seamless

I’m struggling to understand how to ensure that the textures remain seamless across the additional wall pieces.

I hope that clarifies my problem.

Here are my example pictures:

I hope someone can help me out

Thank you :sob:
