Transparency, fade in on several materials

Support Materials and Textures
1

Hi, I am trying to make a fade in on two materials. I am using the same group to make the fade for both materials but then i get this “x-ray” effect. I would like to fade in the two objects but only see what is “outside” Like you would if you fade something in AE/PS etc. Maybe something with Camera Ray?

Turn on Backface Culling on the Material Properties and turn off Show Backface

Ok, will try but my problem is if you imagine a car with an interior. If you want to fade out/in the whole car you don’t want to see the engine/chairs etc.You just want the whole car do disappear.

You can fade whole objects based on materials in the compositer using crypto
matte.

Hope that helps.

In the material editor you can also use the holdout shader. (Cycles)

Cryptomatte is for making masks right? How would I go about to fade
an object in over time? Let´s say I want to fade a whole car in from 100% transparency.

Think I solved it. I put an Set Alpha node after the Cryptomatte/Image an use the Alpha Slider

Not solved :)… Need more ideas
