hey guys - sorry i've been a little inactive the past couple days - just got a chance to look more closely at some of the earlier messages!
@Hephaestion02 the sunlight issue you mentioned - i'm experiencing that one as well. not sure if it's in any way related, but it's appearing in my game just like you described. it hasn't been at the top of my list to look into because it's limited to like certain small surfaces that are in shadow during the afternoon... plus i've only been in build/buy lately so i just shift the time of day setting and have been ignoring it.
also - not sure what exactly caused the issue to "spread" to maxis objects/textures for me... it just happened when I decided to leave the 3 cc televisions in my game despite having them show the glitch on their screens. after a few days, the glitch just showed up on everything.. then I removed the televisions and at that point it stayed limited to particular objects.
@Bluebellflora thanks for this! i'm going to try it out on some of the CC objects I had an issue with, especially the items by Peacemaker and LittleDica. If there's anything that I apply this method to that still shows up in-game with the glitch, I'll report back with more details!
Additionally, I've been in touch with LittleDica about the issue, since they are pretty well-versed in this technical stuff, and they've given me some steps to try that might help shed more light on the situation! Will let you guys know when I have a chance to check it out!
