UV Map?

I know you guys are probably sick of me. I didn't think this one was going to be difficult. I took two necklaces and merged the meshes together. That was easy. The original textures for both meshes are in the exact same spot on the diffuse map, so now the textures overlap. I've been googling and I assume I need to redo the UV map, but I can't figure out how to do it. The only part that should be pink is the band around the neck. My files

Hello This is a tutorial explaining UV Mapping that I found particularly helpful recently which should give you some basics. What you need is a little more complicated on the grounds that you're doing a CAS item and not an object. CAS items have a limited space that they can go in, lest they overlap with other CAS items when your sim is wearing them, so you have to be careful to stay within the texture space for necklaces. Unfortunately, you'll probably have to redo your package if you've already joined them. You need to put each object into edit mode before you join them and scale down the uv map to .5. Once you do, you can put one on top in the space and one on the bottom, making sure they don't overlap. Then you can join the meshes. The uv map should then have both, without them overlapping. Then you can export the UV map (according to the tutorial above) and make a merged texture of the two in your editor of choice. |

Hi. When you create something with a curve, enable Use UV for mapping and it will create straight uvs Before duplicating one object, make sure to unwrap it ( the spheres). Unrelated to the problem, but you need to delete uv_2 and transfer uv_1 from the upper body. The whole accessory should be vertex painted with 007F00 Also, you need to install the latest version of s4s because yours had maps-related bug that led to the game crushing
Uv unwrapping is pretty straight forward. Torus is the best example to show it. - doing Smart UV Project will unwrap the object by the specified angle, which works well only for angular objects like tables, shelves, etc:  - doing Project from view works better, but the texture looks warped because uvs are shrunken. A good portion of the uv space is unoccupied and wasted:  - but if you were to just break those loops by creating two seams, it would straighten. You want to put seams in places where they are not visible, if possible. The edge loops inside the torus are shorter than those on the outside, so you will get neither a perfectly straight uv island nor textures projected without stretching:   - if the goal is to have no stretching at all, you need to break this big uv island into multiple. This way the uvs will be able to match the length of the edges. As you see, 4 is still not enough:
- if the goal is a straight uv island, you can straighten one face and make others follow with Follow active quads. You can break the big uv island into two to get bigger uvs and better quality   Now look at the chains on your necklace. It's the same torus. You can either unwrap it into a straight uv island, split it into multiple and fit into the available uv space, or create the seams ( where spheres cover them, if there were edge rings below them), stack all these uvs on top of each other, and get a high quality chain texture. The heart? the same torus, but hear-shaped. The Choker? the same torus, but with 4 sides and broken, etc |

Wow okay I'm still super confused but I got it to work so thank you. I was hoping that I could do the choker in two colors split down the middle, but the map doesn't work that way. I think I would have to redo it, and I'm not sure I want to attempt it lol.

You can see how your UV islands affect your texture in Blender and you can edit your UV islands and see the effects in real-time. The method you use depends on what version of Blender you use. If it's a version before 2.8 then switch to texture shading mode, put your mesh in edit mode, then in the UV editor press A to select everything, then import your texture.  You'll need to press N to open the side panel and switch the shading. See where it says "multitexture?" Change that to whatever the other option is. You only need to do this if you can't see the texture on your mesh. And sorry if the screenshot is confusing. I know I have a better one but I can't find it.   If you're using a version above 2.8 the method is different, of course. Go into the materials section (1) and press "new" (2). Click the little circle next to "base color" (3). In the new window that pops up, choose "image texture" (4).  Click the button that says "open" (5) and navigate to your texture. Click the arrow next to the viewport shading buttons and make sure it's set to texture (6).  You may need to put your mesh in edit mode then (maybe) in the UV editor press A to select all of your UV islands to see your texture in the UV editor. The beauty of this, as I said, is you can alter your UV islands (scale them, move them, whatever) and the 3D viewport will show how it looks and it does all this in real-time. |
