OK I have an advanced lighting question (advanced for me anyhow):

The only way I know how to do lighting is to have a dark layer on top of the playfield and add white elements to it with "destination over" rendering.. (or something like that)

What I am trying to do is have lighting that only affects a middle layer and not the background.

The background is space. So I only want the lighting to affect the spaceship sprites... not the stars and stuff behind them...

Any ideas?

You'll need to go to layer properties and enable the "force own texture" option. Your blending source and destination objects need to be in the same layer.

For which layer? I tried "force own texture" on the space layer and nothing changed.

The layer you want blending modes isolated on.

You'll need to apply the blends on the objects within that layer, rather than the entire layer.
