4.7 to 4.8: Weird materials, particles, colors, etc. What happened?

Hi everyone,

I was wondering if I’m the only one having trouble with this. I migrated my 4.7 project to unreal 4.8 and many things are weird/broken/wrong on the updated version. Things like colors, materials, scale of objects, weird particle behavior, etc.

Anyone else experiencing this kind of thing or is it just me?
