Blender UV Editing: Adjusting Pre-Unwrapped Objects from Sweet Home 3D

In this tutorial, we’re working with a pillow model imported from Sweet Home 3D, which already comes with its own UV map. Instead of starting from scratch, we’ll use the existing UV unwrap to apply a custom texture from our previously created texture atlas — and we’ll make sure it displays correctly on both sides of the pillow.

This is a great example of how to adjust and repurpose inherited UV maps in Blender without the need for a full re-unwrap!

✅ In this video, you’ll learn how to:

Import a model with a pre-existing UV map

Assign and preview textures using the Material tab

Work in Blender’s UV Editing workspace

Use Move, Rotate, and Transform tools to align textures

Understand mirrored UV issues on double-sided surfaces

Use tools like Grab, Relax, and Pitch for UV fine-tuning

📌 Perfect for:

Blender beginners

Sweet Home 3D users migrating to Blender

Anyone learning texture atlas techniques

Creators working with pre-made assets

🎬 Next up: We’ll take the cushion apart and re-texture each side with different fabrics — sewing in 3D, Blender-style! Don’t miss it.
