7 Tips and Tricks for Beginners

7 Tips and Tricks for Beginners

UV mapping is one of the most essential foundational skills to learn in 3D modeling—you’ll need to unwrap your mesh before you can apply a texture to it. UVs in Blender aren’t difficult to use, but getting acclimated to how they work takes some practice.

A UV is a 2D plane with coordinates that correspond to every point on a 3D object’s surface. What is the surest way to cross this bridge without making a mess? Here are some of our top UV mapping tips in Blender.

1. Your Seams Aren’t Accounted for Unless You Use the Unwrap Command

Using the Unwrap UV tool in Blender.

This one comes right from the Blender manual itself—even if you’re slicing it down just like a pro, Blender doesn’t use Seams to unwrap a mesh unless you’re actually using the Unwrap operator.

You’ll find Unwrap under the UV dropdown, as well as in the context menu that U prompts in the viewport. Before hitting the button, make sure that your entire mesh is selected.

Generate UVs is another popular avenue to take at this juncture, but it won’t always be the best way to go. The Unwrap command flattens the model as efficiently as possible while leaving all of your Seams intact.

2. Minimize Texture Distortion by Modifying the UV Map Directly

Modifying a UV map in Blender.

Texture distortion is usually pretty easy to spot. Thankfully, you can modify the geometry of your Blender UV itself using all the usual commands: scaling, rotating, and translating, as well as a bunch of cool UV sculpting tools. You’re able to shove things around until you’re left with something uniform and true to your 3D model.


If anything looks fishy in terms of the UV structure itself, you can also use Seams and Stitches on either the 3D mesh or your 2D UV map to help Blender out. Enabling Live Unwrap puts you right in the cockpit—instead of hunting and pecking, you’ll be working in real-time.

Many UV operations overwrite the UV map completely, giving you something totally new. If you’d like to apply multiple processes to different parts of your mesh, you can Pin and Unpin them as you progress.

The P command can be used to preserve a part of your UV mesh that’s already working well while giving the program another chance to unscramble the rest separately.

If you’re using an option like Project From Face and are putting the UV map together piecemeal, you can grab each difficult part of the model and then generate an automatic UV afterward for the rest. Pins are also great in conjunction with Unwrap and Live Unwrap.

4. Proportion and Scale Matter

The proportional relationships between the geometry of your UV map along either axis can sometimes pull or squash the applied texture unfavorably. Aspect ratio is easy to control when most of your polygons are around the same shape, ideally square quads. Clearly, this won’t always be the case, but it may sometimes be the root of the problem.

Enabling Display Stretch in Blender.

You can see whether or not your UV map is stretching by clicking into your UV panel overlays menu. Toggle Display Stretch for an uncensored glimpse into where you’ve gone wrong.

Adjusting the scale and placement of these UV mesh elements will update this stretching heat map in real-time; the darker the blue, the less your texture is being stretched by the relationship between the 3D model and the 2D UV map. You can also apply a Blender UV Grid as a texture for more insight.

5. Edge Loops and Bevels Can Get You Over the Hump

If you’ve ever completely Flubber-fied a mesh after subdividing it, you already know this trick. An extra Edge Loop or a Bevel prevents Blender from totally steamrolling over crisp edges that you would like to remain intact.

The same principle applies loosely here—a razor-sharp edge may take on your applied texture unnaturally, even if your UV mapping is totally fine otherwise. The PlayStation 1 look is long behind us. It’s time to set the bar higher for ourselves.

6. When in Doubt, Follow the Reference Photo

All 3D artists should work from reference whenever possible. It’s easy to find inspiration in the natural attributes of real-life objects. There are plenty of ways that you can make realism a priority in your own work—hiding UV seams is one obvious example, as is standardizing the scale of a wood grain texture throughout the model.

Think your way around the entire 3D mesh, inside and out. When in doubt, you can always hit the L key when your cursor is hovering over any part of the model in the 3D viewport. The problem area of your UV map will be highlighted along with its 3D counterpart.

7. Just Reset Your UV Map

How to reset UV maps in Blender.

Sometimes, we really work ourselves into a corner. Often, it’s not worth your time to sit there trying to untangle your UV map vertex by painstaking vertex.

Instead, you can reset the entire thing and start right from square one. From the UV dropdown above, choose Reset for a fresh, new start. You can also select the entire mesh and use the Clear Seam command to try a different approach.

Experimentation is awesome. To stay on the safe side and to prevent yourself from losing your work, we recommend keeping a backup of every successful object before trying anything crazy with it. That way, you’ll always be able to try something different without worrying about losing yourself in the hole.
