hello, so i have a question today about appearances. the machine im working on is about 90% paint. so as of right now all of the paint color is saved as an appearance file, and is set on all parts that need that color. one problem i noticed is when i render this it comes out too glossy and shiney, so i have been playing around with those settings but one thing i noticed is when i change the reflectivity of that appearance file it doesnt update to all of the parts that uses it. is there a reason for that? i figured since they all use that same file that any changes i make will reflect elsewhere. is there a way to do this? or do i have to manually change each parts settings over and over again?
