My Mask Disappears when it becomes a 3d layer

Question

Hey Everyone,

I'm working on a project and in the project I am suppose to take a solid and make it into a ring using masks. I have no problem making the ring, but the next thing I have to do is make it into a 3D layer. Once i do that, I can see the lines for my mask, but the mask itself is gone. It becomes a solid again. The project has it set that the masks are set to both subtracted, and one is inverted. Can I get some help into what could be causing this and how to fix it please?

Thank you.

If the masks are not working then the blue layer is not a solid (pixels) but it is either Pre-composed with Continuous Rasterize turned on or it is a shape layer. You can solve the problem by changing the 3D rendering option to Classic 3D or using a Solid as the blue layer or pre-composing the shape layer before you add the masks, or Pre-composing the shape layer with the mask and making the nested comp (pre-comp) a 3D layer.

It is important that you check the notes when you change the Render Settings. There are a lot of things disabled when you enable the C4D rendering option.

Hi there,

Thanks for reaching out. I see that you are having trouble with Mask in After Effects.

I tried this at my end but everything worked as it should. Is there a certain action that triggers this? Is it happening randomly or in all the projects? Also, what is the exact version of After Effects are you using: https://community.adobe.com/t5/after-effects/faq-how-to-find-the-exact-version-of-after-effects-you-re-using/td-p/9972137?page=1

Let us know, we're here to help.

Thanks,

Nishu
