3D layers won't show up in renders!

[CCheukKa]

I have briefly worked with 3D layers before, and they have worked fine. I don't believe I have changed any settings from last time since it was literally just days ago. But for this project, I can't seem to be able to get the preview to render without using Draft3D, and when rendering/exporting, all 3D layers are invisible but somehow still consume computation time.

I have tried clearing the cache, switching between Classic3D and Cinema4D, CUDA and OpenCL and software rendering, rendering in AE and Pr and AME, but nothing works. Help would be much appreciated! 🙂

idk what settings I should be touching so here is everything that I can think of to be related 😛

Render Settings

GPU Infomation

Project Settings

Composition Settings

Why using C4D setting?

[CCheukKa]

As I mentioned, I tried all combination of settings that I can think of. Classic 3D, C4D, whatever. Nothing works.

What does the 3D layer look like in your timeline?
What do all of layers in your timeline look like?

Here are the layers:

Thanks!

Have you tried turning off the lights?
What about turning off layers 3 & 4?

[CCheukKa]

I tried both but still nothing.

Only the composition background is showing.

Can we see your whole composition window? 

Somethings that occur to me:

• Could you have accidentally set a work area that doesn't contain the camera?  
• Are the video files able to render out from AE (in a new comp, 2D).  If not, that could indict a codec issue.
• Is the Active Camera or 3D tracker Camers set as the view in the comp window?  I'm wondering if it's accidentally got switched to another.

UPDATE:

I had the idea to make a new composition and create the camera and import the footage and pre-comps from scratch, then copy over all the keyframes, and it seems that this did the trick. I still have no idea why the original composition is bugged, but it is now resolved (kinda). Thanks to everyone who made suggestions 🙂
