Common Beginner Mistakes: How to Fix UVs (A Table)

May 9, 2017

 

This tutorial is dedicated to the Maya beginners. As new 3D artist, UVs can be a challenge and there are a common thread in making mistakes during UV mapping. This tutorial is to show you how to fix, cut and sew your UVs. Good UVs = Good Texture Layout!

Hey guys, this is Monica at Academic Phoenix Plus, and today is going to be a little bit different. I'm teaching an online class and I wanted to show you some of the mistakes most students make when they first start UV mapping. In this example, I am going to helping the student UV map their table. Alright, so let's get started!

 

You did a good job on the model but as you can see, the UVs is the default cube.  So let's say if I create a cube.  You can see that the cube and your object has exact same UVs, except it's got a lot more edges.  When you put the texture on, it's not going to look right so we need to fix the UVs. Your object is pretty simple so I'm going to show you a couple of methods on how to UV map this.  Usually I take a look at the basic shape and breaking down into shapes.  For example, up here at the top is probably going to be a Planar Mapping (anything flat).  Then these guys, your legs, would be Cylindrical. Sometimes you might get lucky and go to UVs and do Automatic Mapping and what it does, it projects on all six cameras.  You're going to get a lot of pieces so I'm going to spend some time sewing them together. 

 

I want to have as little edges as possible. Alright, so I'm going to go ahead and grab some Edges.  I'm going to grab these guys right here, for example, and I'm going to go to here and then Stitch together.  What it does is that it moves the object, it combines them together. So I'm going to grab these edges and what I'm trying to do is just avoid as many Seams as possible. So Stitch together, Stitch together, Stitch together.  You might want to grab these guys here just to avoid all that.  Stitch together.

 

Alright I'm going to grab this Shell. Control + right click, To Shell. Move that out of the way.  Let me see what it looks like with a Grid. You can see how the UVs are falling well but the problem is just too many Seams.  It's going to be very challenging to work with all those seams.  Let's see the next part is, if I grab this Control + Right Click, To Shell. I look below it, you can see this area now. What I could do is just leave it and just overlap it because a lot of people are not going to see the bottom of it.  But if people were going to see the bottom of it, you might want to Sew it.  I'm just going to go ahead and move it over here. 

 

Let's talk about the legs and we have a lot of pieces.  Usually I try to find out where all these pieces are. I'm going to grab this, I just over here and Stitch together, grab these guys and Stitch together, got these guys and Stitch together.  So again, I'm trying to avoid as many Seams as possible.  You can see that this piece right there, so Stitch together, Stitch together, Stitch together. Make this workflow a little faster by selecting more than just one edge and Stitch together.  That's moving along.

 

Right Click>UVs. Then select one UV, Control + Right Click>To Shell, move it back in here. Let's see what these guys are. Let's go to Edge. We probably do want to start sewing these guys together.  So again, Stitch together and it falls here so I might leave that alone. Grab these, Stitch together, Stitch together, move it aside. But I'll find out what's going on here. To Shell. Yeah, that's what I thought. Okay, so let's find these guys Stitch, Stitch, Stitch. Grab one UV, Control + Right Click>To Shell, Edge, Stitch together. Okay, so that's good. 

 

You can already see how easier it is to maintain if all these pieces are actually combined.  That's the bottom, so again if you want to share texture information, you just overlap them so make a big chunk, Control + Right Click>To Shell, move it over here.  This can be a little bit bigger, To Shell. Make it a little bigger. Move these guys out of the way. Start overlapping them or at least bring them close by.  We got to place these guys somewhere.  Let's see where they are.  At the bottom, okay.  So we'll attach them at the bottom.  Grab the Edge, than Stitch together. Grab these edges, you can see where it's going to be, down here. Stitch together, Stitch together, and one more Stitch together.  Alright, going to move this up. I'm going to start moving things around so it maximizes my UV space.  To Shell. Let's see what the grid looks like.  There you go, so that's going to be a lot easier to texture.
