How do I mask a light object that has destination out on it?

Hello, like I said I have a sprite that is on a black layer that is not transparent and that is set to 80% opacity. On this layer, I have a large circular sprite that has a destination out blend mode so that it looks like a spotlight cutting through the layer letting you see under. What I'm wondering is if there is a way to cancel out the circle's destination out blend mode using another effect or blend mode. I have been trying to use destination atop on a mask but you can still see lighter areas on that mask. All ideas are appreciated.

Can anyone help me with this?

The issue is difficult to understand. Can you post a demo project and an image of what you are trying to achieve?

Hello dop2000 sorry for the confusion here is an example capx

There is also an official example in C3 called Stealth Game.

dop2000 Thank you for the response, I'll have a look at those first two links asap I have looked at the stealth game example but I wasn't sure how to use a pasted sprite to replicate what they were doing.

Do you think there could be a way to use the first link to create several light sources?

No, I'm not sure if this is possible. Perhaps if each light source is on a separate layer.

I was thinking about that but as you can see by my example I'm using a semi-transparent layer to emulate darkness so if I spread out my light sources they won't cut through all of the darkness. I am going to look into sub-layers but I'm not sure if I can use destination out to affect the parent layer or not.
