Hello Everyone,
I am making a Apps promo video. I have used a Smartphone model in cimema 4D and ad the video screen through material, but it seems unclear (I have attached the screenshot) when I export it to the After Effects. I guess experts are used luma matte in After Effects to add overlay screen into 3D object.



I want to know,
1. How to add luma mate in After Effects in 3D object?
Or
2. How can I clear the screen in Cinema 4D

Regards,

You would use C4D to make a luma or alpha matte of the screen, and you would use Mocha in AE to track the screen. Once they are done, you can make any kind of screen you wish in AE.

You can have C4D create luma mattes for specific objects for you. These are called "object buffers."

You can also have C4D export camera and null/solid position and rotation information via the external compositing tag.

Slightly off subject, but "Instant massaging" on the orange screen sounds like a typo.

Maybe the phone has a really strong vibration motor in it...
