***Please note*** This can be a standalone tutorial, but it is also part 5 of the Create Modular Assets in Blender for UE5 for our Resident Evil Inspired Hallway.

Part 4:
Software/addons used:
Blender 4.3
ZenUV
UV Packmaster 3
Blender to Unreal
In this tutorial, we continue the Modular Asset series with a full breakdown of UV Mapping in Blender, focused specifically on preparing assets for game engines like Unreal Engine.
In the first part of this video, I cover the fundamentals of UV unwrapping and explain how I approach setting up clean, efficient UVs for game-ready assets. We’ll talk about:
UV mapping basics for beginners
How to unwrap meshes cleanly and efficiently
Setting up UVs for seamless tiling textures
Creating clean, readable UV grids
Tips and techniques I use daily for modular assets
Common mistakes to avoid when prepping assets for Unreal Engine
This workflow is designed to make texturing easier later on, whether you’re using simple materials in Unreal or planning to texture in Substance Painter (which we’ll cover in a separate video).
If you’re creating modular assets, environment art, or game-ready models, this tutorial will help you build strong UVs that hold up in production.
