Strange CAS mesh problem

@SimGuruModSquad

Hello. I've run into a very strange problem with an original mesh created by a user of one of my tools. It's a male jacket top. With roughly half the EA pants it looks and works fine. But with the other half the sim's left arm is wrongly positioned:

I've tried everything I can think of to fix it. It seems to definitely be the mesh since I've cloned an EA top and replaced the lod0 mesh with this one, not changing anything else, and gotten the same problem. Also I don't understand why it works fine with some bottoms and not others.

It looks to me like the slotray intersection data isn't working on the left side. Do you know of anything in a mesh that could disable it in combination with some bottoms but not others?

I'm linking to the original package in case you'd like to see it. The region map is messed up but that didn't seem to make any difference to this problem.

Thanks very much!

    I agree that this looks like the slot rays aren't being calculated correctly. I just exported and reimported the mesh using Sims 4 Studio (which automatically corrects many slot ray issues), and the item works fine with all the garments I tried. For example, the original garment wouldn't work with the heart underwear, but the fixed one does (original on the left, after import/export with Studio on the right):

    Also, with the original .package you posted, I noticed that the arm placement is very garment-dependent. This was also true if I just used the same .package and exported/imported the mesh using Studio although none of that garment-dependence caused the arm to shift the wrong way (in the picture above, the arm is moved a bit further away from the body than is usual). However, when I made a new clone using Studio and imported the mesh into that instead of the original .package, this garment-dependence displayed by the arm did not occur:

    The problem does not seem to be inherent to the mesh itself but rather with how it was handled when it was imported into the .package you posted.

    Hi Cmar, I don't keep other peoples' content on my computer after I've found a solution to their issue, so I don't have the fixed .packages anymore, but the steps aren't difficult to duplicate. :)

    Thanks. Could you upload and link the corrected package so I can see what changed?
