Blender Newb - Separating jacket from shirt (Texture issue)

Could you post the package in order to take a look ?

Hi leeleesims1 ,

This is happening because the texture for the jacket covers that part of the sim's body on the nude top. You may have noticed that the collar texture is in the bottom right of the texture in the extra area shown in brujah's mini-tut HERE. What I would suggest is that you move the rest of the jacket there as well so that no part of the jacket gets painted onto the nude top like this:


You will need to move the UV map of the jacket to the new part of the texture but leave the nude top where it is so that it looks like this:


Here is the result in CAS:

The texture itself will need to be moved in your 2D editor. For the UV map, you may want to try OM's accessory tutorial if you aren't familiar with that yet. Her tutorial shows from start to finish how to work with a CAS mesh in Blender and get it into the game. It goes over mapping, vertex paint and weights. Part III in particular will go over the basics of how to move things in the UV editor.

You are welcome If you have questions, just ask and someone here will help out.

I'm not sure what went wrong but in your new blend, it looks like some of the mesh groups are overlapping



The main group with the jacket looks fine where you re-mapped it, but there are groups with duplicate geometry that is probably poking through that.  You sent the package and the screenshots, but if you also have the .blend from your latest edits it could help us to determine the problem.

Hey leeleesims1,

It looks like part of the clipping issue is because you still have some duplicate geometry in groups 3 and 4.  An easy way to get rid of that is to delete all but one triangle and move that triangle out of sight into the sim's body. The other part seems to be from the part of the sim's chest that is under the jacket.  If you turn on backface culling and look at the chest part from the inside, you can move the parts that don't need to go that far toward the middle to minimize the clipping.  In the picture below I moved one of them, but they all be moved closer to the edge of the jacket. 



As for the other part, you need to put a backside on part of the jacket so that it can be seen through the gaps.  One way that you can accomplish this is with Blender's Solidify modifier.  If you just use it on the whole mesh, you will get a ton of extra polygons, so you will need to select the part that you want to add a back side to and separate it from the rest of the mesh.



Then add the solidify modifier.  I set the thickness really low because the default distorted the mesh somewhat.  Then apply the modifier and join the separated group back to the main group.




Here is how it will look in game, notice there is still a gap where you may need to include more of the nude top.

I see this post by UN that shows a more detailed layout of the "extra space" on the UV Map. It looks like you will need to shrink it down to that area for extra top and keep it off the extra bottom. It looks like the template in the tutorial section may need a little update.
