Hiya peeps!

Im trying to make a disco scene where the tile lights change, as spot lights from ceiling move around, as disco ball rotates reflecting lights.

----------------------------------------------
1) Disco floor = it uses glow attribute for shader, so i dont have to make.. 48 lights underneath.

2) Ceiling lights = they use colored spotlights

3) Disco Ball = phong E w/ reflection + raytracing reflection
----------------------------------------------

The glow works well, lights up in sequence as i want. Even when a spot light shines on it, it look as i want.

But when 2 spot lights meet each other, the glow becomes crazy bright.

I messed with the glow intensity, and its pretty low on the picture but still it gets crazy bright when 2 or more spot lights hit it.

So i messed with the spot lights. Making it decay makes the shape of light casted into wall to disappear, if i raise intensity.. makes glow go crazy again.

So.. would anyone know a way to not let the spot light affect the glow too much? or when spot lights meet, let it not add up too much light? The floor is blinn, and i tried getting rid of all specularity and reflectivity.

Thanks.
