UV Texturing is the process of mapping a 2D image texture onto a 3D model. The “UV” coordinates tell the engine exactly how the texture should wrap around the surface, so colors, patterns, and details appear in the right place.

Well-made UVs prevent stretching or distortion and are essential for achieving clean, accurate textures on any model.

This process is called UV wrapping, and in my project, I wrapped building textures so they don’t tile or repeat awkwardly. For specific faces, like windows, where every face should look identical, I used a uniform UV scale to keep them consistent.

Here are some valuable tips for using UV’s in Unreal Engine:

• Use Blender to create UV’s before exporting your mesh. Personally, I find Unreal Engine’s UV system to be very confusing. Unreal Engine works fine for minor UV adjustments after importing, but it’s usually better to do the main unwrapping in Blender for full control.
  
• Make sure to unwrap faces together, not individually. This keeps textures aligned and prevents awkward seams or inconsistencies.
