Pickwhip 2 x 3D plains together.

[Astonished_Raindrop6278]

Hello, I need an expression while linking the rotation and position peramiters of two 3D plains to follow to each other. How can I displaice one plain by a single pixel so it doesn't clip in to the other?

Many thanks.

Hey there,

Welcome to the forum. Thanks for the question. While we await a solution from a community or team member, let us know any further details about your comp. I did find this expression that may help you. See if it works: 

thisComp.layer("Plane 1").transform.position + [0,0,1]

I hope we can help you soon.

Thanks,
Kevin

If I am stacking 3D layers, I always set them 1 pixel apart by adding this expression to the position property of the bottom layer. Then I link the Rotation and Orientation with these four other expressions. I then only have to keyframe the top layer.

//POSITION
thisComp.layer(index - 1).position + [0, 0, 1];

//ORIENTATION
thisComp.layer(index - 1).orientation;

//X ROTATION
thisComp.layer(index -1).transform.xRotation;

// Y ROTATION
thisComp.layer(index -1).transform.yRotation;

// Z ROTATION
thisComp.layer(index -1).transform.zRotation;

Add those five expressions to a 3D layer, press the 'u' key twice to reveal all modified properties of the bottom layer, drag a selection around the Position, orientation, and rotation properties, then choose Animation/Save Animation Preset from the Animation Menu and give it a name. You can then use it any time to stack layers in 3D space, and it works with all three of the 3D rendering engines.
