Set Falloff of lights

[haimat]

it would be really great if one could set the falloff value of a light source. What I want to achieve is a very bright light, but with basically (very low) distance. Full brightness on one spot, no softness whatsoever. But only for some lights.

Would that be easy to implement?

For what it should be used? I mean if this will not have to deal with things like shadows or complex lighting of the underlying environment, than I suppose not to complicate the things and use the simple small spot sprites instead, which as I think could produce the same effect but without thousands of useless checks and iterations in lighting engine :)

In such a case using just a sprite is not an issue. Think of a very dark scene (i.e. low ambient light), then without light source you would hardly see the sprite any more.

You can use following render scenario:

1. Render light-affected scene elements
2. Render lighting (rayHandler.render)
3. Render light-not-affected elements (e.g. spot sprites, UI, other things)

In that case everything rendered at point 3 will not be covered by ambient light.

Yes, I guess hat is correct. I will think about that solution, thanks!

[haimat]

Well, there is one problem with this approach: I need to render various elements in a certain order. When I would now render thos not-light-affected sprites after the rayHandler, then those will always be on top of eveything else. That is not really the expected behaviour :-(

[rinold]

Well, the lights are rendered in one pass also and they are also on top of everything rendered before. There is a problem anyway :(

True, it's a tricky thing... Well, nevermind, it's not that important. The pseudo-3d feature is what I am really looking for :-)
