Film Grain effect?

[marigoldsofthenight]

I've been trying to add a fine 'film grain' look to my scenes with alpha channels, but I'm wondering if there's an easy way to overlay the effect over the whole game, menus and all?

I don't think there's a good way to do this.

I don't think it can be done with simply "over" or "additive" blending. If there's a way to do it with just those operations, we can do it.

You can try adding a new layer to your game in the options script like:

Code: Select all

config.layers = [ 'master', 'transient', 'screens', 'overlay', 'texture']

Where "texture" is the new layer. Then you take a bunch of transparent noise images, animate them and show them on that layer. This may only work for in-game, I don't know about menus but I think it would be a bad idea to have a film grain effect over them for usability reasons.
