Alpha propagation


Is it possible to avoid alpha propagation as shown here :arrow_down: while still using groups?

snapshots don’t work for me, the groups are too big, like 20000*20000 big in some cases. May be there is another way?

Can you give us more information? What exactly are you trying to achieve?

I don’t think that is possible unfortunately, but I would love if someone has a simple solution for this. :slight_smile:

It looks really terrible when using alpha transitions and objects shine through each other.

Just remembered I wrote a blog post on a similar topic a couple of years ago, about how to create a proper fade in/out effect on scene transitions. It’s not exactly the same thing that you’re looking for, but maybe it could be of interest anyway.

You may have missed one part from the documentation:

A display group’s width and height are determined by its children, specifically the union of the children bounds. In contrast, snapshots have a pre-defined width and height, so children which reside outside those bounds will not render.

It doesn’t really matter if you have massive groups as long as you keep your snapshot size small (and there’s really no reason to go past the screen bounds).
