Subject: Re: [AE] expression to check for a 3d layer

You can check for a property only 3d Layers have, for example =20
var threeD =3D true;
try =7B
thisComp.layer(=22Control Layer=22).materialOption.ambient
=7D catch (err) =7B
//Not a 3D layer
threeD =3D false;
=7D

threeD is either 1 or 0 numerically.

regards,
Satya.
