Request: 'Alpha' parameter for Geometry COMP

In my scenes, there are many times I wish I could easily ‘fade’ entire geometries in and out of existence.

Currently, the way I do this is by gradually changing the alpha of all the child MATs + toggling of the render flag/par.

It would be useful if Geometry COMPs had a top-level 0-1 Alpha parameter that multiplies the final total/overall transparency of all of the Geo’s contents. That way, one could easily fade in/out complex Geos with many child geometries and various materials, without having to mess with the contained materials’, or per-point alpha.

Has something like this been considered?

You could build this functionality yourself using a find DAT and a custom parameter on the geometry COMP. Then, automatically reference the parameter to all materials with the COMP.
