3D objects rendered transparent

[cdpark0530]

I have a 3D object in format `.glb` which I can see its shape on Adobe Dimension, but I can't on After Effects.

(I wanted to attach the file but it's not uploadable file type here)

`Fence Metal Black.glb` is the file and as you can see below, it's rendered transparent while there is still cube outline.

This .glb file is seen on Adobe Dimension.

Hi cdpark0530,

Thanks for writing in.

Are you able to use the Advanced 3D renderer? Go to Composition Settings > 3D Renderer tab and check if you can see Advanced 3D Renderer in the drop-down list. 3D objects can only be previewed with the Advanced 3D renderer. If Advanced 3D Renderer is not available for you, check if your system meets the minimum system requirements for After Effects. Advanced 3D Renderer needs at least 4 GB of VRAM.

Let us know.

Note: Moving this thread from Bugs to Discussions for troubleshooting.

Thanks,

Nishu

Thank you for reply.

I just checked if I can see the object at least in output video not preview, but the 3D object is not seen.

Nishu is referring to the composition's renderer.  It needs to be set to Adanced 3D in order to show 3D objects.  Can you confirm if it is.

If the comp is set correctly, if you post your file here, I can check it out and that will at least confirm if it is an issue.

Thank you for reply.

I forgot to mention first that I don't have that Advanced 3D option due to the limitation of my PC, but I guess that at least I could see 3D objects in exported files.

I really want to share my project files but this platform doesn't accept those files here.

[ShiveringCactus]

To share a file, you'd have to use a 3rd party service like DropBox and post a share link.

You can still use C4D Lite to render the models in After Effects.  I'm not sure if C4D Lite can import GLB models, but you could convert them to OBJ files using the free Blender program.

Thank you for reply.

I digged C4D and could render the 3D object with it!

Although it has limitation, like to make a 3D object sit on an environment while using camera, I have to follow these steps:

1. Make a composition of the 3D object.

2. Create a camera in the composition.

3. Set Project Settings > Camera as Centered Comp Camera in cinware effect of the 3D object.

4. Adjust the camera so that the 3D object looks like sitting on the environment of your main composition, following the main camera's movement. (You have to look at the main composition and the 3D object composition in turns consistently until you make it)

Maybe I just don't know how to use some features to make this work easier.

Still better than nothing. But for later use, I'll definitely buy an external graphic card for my laptop to use Advanced 3D renderer...

Thanks ShiveringCactus.
