But instead, I'd like to get the actual result I would get in 3ds Max:. Make a mesh from our mesh of interest's UV's as demonstrated here How to get data and edit it on UV map edges?

For this one have used numpy to quickly make the mesh. Moved the origin to 0. Removed doubles and marked boundary edges selected with bmesh, then as freestyle edges. Freestyle SVG Exporter. If you have any concerns about all the manipulation of the object separating parts, deleting faces, etc you can do what I did and write in the script to first make a duplicate of the object and after exporting the UV Layout you just delete the copy.

S: It would however, be great if we found a way to store all boundary edges of the UV islands into a variable and then after that make Blender display only these edges in the UV Editor with sync mode turned off. Sign up to join this community.

Seams are a big part of UV unwrapping. We can think of seams as the manual approach to UV Mapping. A seam can refer to multiple things.

I will try to explain three definitions starting with the most important one. The edge will get a red color showing we marked it. Instead, they will split apart as Blender lays out the UV Map with the goal to minimize stretching.

The goal is to place seams in a way so that when we run the unwrap operation Blender can lie out the UV map with minimal stretching. So why not just mark every edge as a seam? That brings us to the next seam type. Another definition of a seam is when the texture is not seamlessly moving across an edge dividing two faces with a clear difference in texture. I hope you can see the difference here. One definition is an edge, a 3D mesh element we marked, while the other results from a badly mapped texture.

The third definition is less common, but you may come across it. A seam may also refer to a clear seam in the texture image itself. This is more of a warning of bad terminology. Sometimes artists use the wrong word here. For instance, if you have a wood plank texture, sometimes you can hear the line dividing two planks in the texture called a seam. The line dividing two planks in the texture is not actually a seam, but I have heard this terminology used many times. The takeaway is to know what is being referred to.

Now we will jump into the different unwrapping methods available in Blender. These are different algorithms that Blender uses to calculate the UV map for a given mesh object. Press "U" in edit mode to bring up this menu. You can also go to the UV menu in the 3D viewport header while in edit mode. Blender takes selected faces as input and spits out corresponding UV coordinates for us to map our texture. Unwrap is the only method that uses seams as its metric for where to cut the mesh.

After having cut the seams Blender tries to lie out the UV map avoiding as much stretching as possible. We have two operator options available. Most of them having a minor impact on the unwrap. The margin can also be good to keep in mind. We should have a few pixels between our UV islands to avoid any bleed over. Next up is live unwrap.

We can also find this feature in the UV editor if you go to the UV menu. These are two different features though even if they have the same name.

I never use this feature, but when I dove deeper into it, I found that it is not that well documented. I also found that it does not work very well together with other unwrap methods.

However, by itself and the right circumstances, I think it can be a very useful tool. But since it works best on its own, I will cover it in full in the workflow section. For now, I will just say that when activated in the 3D view it will do the unwrap operation on your entire mesh every time you add or clear a seam. This is probably the most useful for hard surface modeling, architecture visualization, and mechanical objects.

When using it, Blender will determine where to cut the mesh based on angle data. When you have a hard surface, object it can be a good idea to start with a smart UV project and see what Blender gives you before starting a manual unwrap. There are a handful of parameters available, such as margin that lets you decide how far apart islands will be from each other. Instead, we keep the correct aspect according to the 3D mesh.

This is one that I almost never use. Lightmap is geared towards game assets that need light baked into them. Blender will take each face and unwrap them individually. The goal is to take up as much of the UV space as possible.

Faces will be ordered by size from smallest to largest. In Blender 2. This is an interesting method for making square UV grids. You can select what you want to unwrap then click activate the face you want as a guide and unwrap using this method.

Follow active quad uses the active quad in UV space, not in 3D space. This is an important distinction. These are meant to be used when unwrapping their respective primitive shape. Note here that these take the 3Dview angle into account when unwrapping. Most of the time, you will get a desired result if you first go into front orthographic view with number pad one before you start your unwrap. Project from view will take a snapshot of the selected faces from your current view and project into 2D space.

I have seen this used as the main unwrapping tool for hard surface objects, but I never use it myself. It is easy to see what you are doing since you literally move your view around and snapshot your selection.

But it is not very time efficient since you must make all these camera changes and selections to unwrap. This is basically the same thing except that the UV map will be scaled to fit the space. This will stack all your selected faces on top of each other, every face filling the entire space. This is good to use together with follow active quad to unwrap the first quad that you then use as a guide.

A big part of unwrapping is making accurate selections. A common beginner mistake is to always unwrap your entire object all at once. The better approach is to select and unwrap each part in turn. I will outline some selection types that I have found useful below, you can also check out this article for more selection tools and how they work. Related content: How selecting works in Blender. When unwrapping we will spend most time in face and edge selection.

We will use face selection to select areas we want to unwrap, and edge select to create seams. Personally, I never have my selection tool set to anything other than box selection. This is the default and allows both for box selection and click selection. Holding ctrl will also add to selection but it will select a path from your active element to the element you clicked. You can tag the path if you are in edge select as a seam or any other marking available for edges. Unfortunately, we can only add one kind of tag at a time.

We can also do other settings for instance, selecting every nth element. As its name suggest, it allows you to select based on several traits. An example is when you want to select multiple faces on the same surface. Between your selection and unwrapping, if you are unsure about your current selection, take a quick look in wireframe mode before unwrapping to make sure that no extra elements are being selected during the unwrap.

A couple of things to watch out for when dealing with UV maps are modifiers and mirrored meshes. Related content: How modifiers work in Blender, an overview. If you have modifiers on your model that is not applied your UV Map may not give you the result you intend. The best example for this is the solidify modifier. The extra thickness added by this modifier will copy the textures pixels that live on the edges of the faces and the backside will copy the front facing UV coordinates.

Other modifiers, such as the array modifier and subdivision surface modifier work better. You will just have to double check. Just one thing, if you find this article helpful, perhaps you will find my E-Book helpful as well. Tried a few sub-methods doing this and non of them work properly. There are some cases in the workflow where uv islands must be touching not overlaping.

I also tried using the Fill option in the texture paint with the object selected and a brand new texture created. This sort of works but has its own set of problems and in the end the result is quite bad.
