So I have a real weird issue, I have a few parts with highlights, and when I was doing smth in studio, I saw that some highlight effects dissappeared from one part (with hl) and appeared on other (also with hl). When I deleted and CTRL+Z’ed it, it fixed, but after some time it happened again. Not really harmful, it’s only visual, but really annoying
Are there more than 31 highlights? If so, try to minimize use of highlights by for example adding all parts that need a highlight to a model and add a highlight to that model.
If they disappear during build mode then I wouldn’t worry about it. I’ve had this issue before and they always come back during play testing. Simply just a weird rendering issue.
