3D layers won't show when rendering. Please Help!

So I'm pretty new to after effects and for my first project I've done some kinetic typography. When I render in Adobe Media Encoder, all my 3d layers just don't show up in my render. Just black. I'm using ray-tracing renderer at 1080p 60fps. I'm using the default render settings (h.264 [mp.4] match source). None of my layers are "guide layers". I'm using the latest version of AE on windows. My pc has a i5 and a gtx 1070. All the 2d pre comps show up fine, just not the 3d ones. I could really use some help. Thanks!
