collision with alpha

[SolarB]

This may sound like a stupid question, but is there any way to get mmf to ignore collisions with the alpha channel of an object? I have big shadows on some actives and the player collides with them, which isn't supposed to happen.

Thanks!


EDIT: Oops, just realised obviously a shadow requires some black and that's what is doing the colliding. Still, any tips on how to handle shadows for objects (non-shader)?

Make the shadow a separate object and just always match their positions.

Done, but now if I have two objects close together (buildings) the shadows overlap. I can't seem to find a shader that blends both shadows together. I've tried making different shaped shadows depending on the position of the building but this doesn't work if the buildings are dynamic (destroyed/moveable in-game).

Is there a shader that can blend two shadows? Another way to achieve this?

In just about every game I know, even professionally programmed games such as Mario, there exists that issue that overlapping shadows get darker where they overlap. I don't think you should see it as a problem

As interesting as that is to know, I don't think this looks at all acceptable:

Unfortunately I need another solution

SOLVED:

After some thinking I decided to make all the shadow actives opaque, put them on a separate layer and just make that layer semi-transparent. Why are the simplest things never obvious?

Even simpler (and using less layers -> faster game performance) just do Always: Bring Shadows to back.
