So you can use that as a template for a working example to get the other trait working. There were a couple areas I missed, one of which is vital. Still comes back to that same problem of Sims Studio not reading the data file fully, so it ending up missing part of its information.
One of them was the tags in the Sim Data. It had gutted those, so those needed to be filled out for the trait to show up as a personality trait in the CAS lifestyle section. Pretty sure this is the vital part that was still missing for getting it to show up in CAS.
It was also missing the icon ID, trait description ID, and had something erroneous in trait origin description. So I filled out icon ID and trait description, and then replaced origin description with a blank 0x00000000 type thing, since it isn't needed.
I also changed the part at the top that says SimData version and set it to 0x00000101 -- not sure if this part is actually needed or what it does, but I was trying various things at the time (copying from a sample Maxis file) and figured it couldn't hurt. So just so you're aware, that is one of the things I changed.
Oh and for future reference, that is one of the things I do a lot when I'm lost, is look at working examples, especially from extracted Maxis files. There are some aspects of the code that I recognize and understand pretty easily now, but there's also a lot of just copy/pasting. My general motto is, when in doubt, copy how Maxis does it. :tongue: And if it turns out to be superfluous later, I'd rather that than miss something important.
