Subsurf Modifier not working in viewport?

I’ve been using the 2.8 nightly builds. As a few days ago, I noticed that my subsurf modifiers on my project are all redded out and don’t show up in the viewport (they still do on render.) This is happening to all the subsurfs on all the objects in my project, including new ones. If I make a new file, subsurf works fine. If I open my project in an older 2.8 build, the problem persists.

Any idea what could be going on? Is this some project setting or something?

The devs are in the process of doing some heavy viewport optimization. I don’t know if that is related, but I wouldn’t be surprised if that was the cause.

File a bug report, just to be sure.

It just seems whacky that it works in a new file but not in my existing file. So it must be something specific to my file settings, not something specific to the overall build.

Turn off “Simplify” :slight_smile:

That was it! Thank you!
