Glitched finger on CAS clothing conversion

I had the same thing (slightly worse) with a s3 to s4 child outfit i did. For the life of me i couldn't transfer to the bottom part of some pants the bones of the feet.. it was a nightmare. I left the bottom part without the feet bones. It clips a little.. but there was literally no way. What you can do.. is click every single vertex around the issue, seeing on the sidebar how the bones are represented and if everything stays at 1 in total. Some vertex must be either overweighted or the other way around.

I managed to solve your problem. But the result of texture quality is not promising

Your problem is about cut number interaction (not rly weight)

Cut number determines how many mesh parts CAS item has (And i don't have any idea how will it determine). In this case, Your "template model" (a model you use as a base) to import your alien outfit has 2 cut parts (cut numbers). Imagine cut number are "number of countries" and vertices that belong to each cut numbers are "populations". And each populations can't mixed up/overlapping

No.1 is that problematic left ring finger
No.2 are the rest of body parts.

If there's any mesh that overlap the area cut number already has (In this case, there's portion of No.2's ring finger mesh are overlapping No.1 ring finger), That will make weighting exceed limit and give us a spiking mesh problem (one of the most common CAS editing problem).



My process to fix your problem
I. I just deleted No.2's some portions of left ring finger in same ratio of what No. 1 ring finger has
II. Join No.1 and No.2 group together 
III. Snap the group of No.1 vertices to No. 2 to connect the finger
IV. Point the mouse cursor over No.1 finger's area and press "L" to select the rest of finger vertices group. how the vertices group are determined is preset by original mesh creation). You should have original No.1 finger vertices all selected
V. Seperate No.1 by press "P" -> selection
VI. Give No.1 back it's cut number

right now, i will upload fixed package for you. For process, i will upload picture to describe them later

The bad news is i tried to come up with idea, "what if I just delete the No.1 mesh , seperate No.2 finger in same ratio no.1 has and give the seperated a cut number same as what original no.1 has". For now,it didn't worked. Spiky mesh still appeared.

sorry for my poor English skill.

My apology for What i posted earlier. I forgot to delete some vertices that overlapping.
Here's solved package (sry again)

and straight from game evidence. :D
