Smart UV Project

- The basic cube projection tool…works well for basic cubes.…But most 3D objects are going…to be more complex than that.…If I used the extrude tool…to give this object a bit more geometry.…You can see that the extra faces…don't get updated in the UV map.…So I'll need to re-project it.…If I now use cube projection,…I get something like this,…but it's kind of a mess.…A tool that might be more appropriate for this…is the smart UV project tool.…

If I hit the U key…I can find the smart UV project tool here.…This settings box comes up…and we'll talk about this options in a moment.…But when I run the tool,…you can see that it breaks the map apart…and attempts to reduce the stretching,…and it scales it all to fit in the 0 to 1 space.…Nice.…Let's go back and take a look at the settings options.…The first one here is the angle limit.…This can be set anywhere between 1 and 89 degrees.…

The default is 66,…but if I set it to say 10,…it would break the map up into more islands.…A higher number like 89…will try and reduce the number of islands.…
