Re: [CC RELATED] Random Sims are shiny and have Texture Overlay

I can't figure out why can't I add a separate reply to this thread. I can reply only unde the message. 

This issue is caused by missing specular map that was "blanked" in the files made between 2015 and 2018, per my observation. Before Island patch everything was working perfectly. I guess EA either have changed how the game reads files with blanked specular, or implemented this glitch involuntarily, but won't fix it since it affects content that is not made by EA, therefore is not their pain in the neck.

CC can be fixed in Sims 4 Studio by either adding a custom specular made for the item (longer, but more correct way) or adding a custom blank specular made by me. The first method is more correct since custom blank specular will cancel specular (shine) map on other items when custom regular specular won't. But if someone doesn't know how to do a custom specular file and wants to keep particular piece of CC in the game, then the 2nd method is the method to follow. The most difficult and annoying part is to hunt down all glitchy CC. I wrote a tutorial about how to find that sort of CC through CAS without going in the game and how to fix it. I won't quote entire tutorial here, and will post the link instead.
