I downloaded a .blend file that is a model of an eyeball. When I first load it up in 2.79, right when it opens, before I do anything to it, it looks like this:
When I open the exact same file in 2.8, again before I touch it at all, it looks like this:
I figured it had something to do with the "method to display/shade objects in the 3d view" selection, but for instance I can put both 2.79 and 2.8 on "rendered" and the 2.79 eye will look fine, 2.8 will look weird.
The blend file is here if you'd like to mess with it: https://drive.google.com/open?id=1mdDOiJLUsz_H5Lsq2eK7vZLwRKuM2ak4
I'm sorry if this is an obvious question.
