simple water?
the colour basically comes from the pool-walls...

Sorry, but that's not totally true.

Even with completely white pool walls, the water will be appear bluish!
Unless it's a very shallow pool.

And that also happens without a blue sky above!

That's because the light absorption capacity of water which effects the shorter wavelengths less than the longer ones. So it becomes blue with increasing "thickness".

hmm...
no idea, how chlorine changes the appearance of water...
anyway, if your pool-walls are blue, as usual, it should look correct, I guess...

exponent 60000...? Here I was thinking 10000 was the limit ... !

Exponent is limited to the maximum possible value in float or double float (dunno, which one)...
100000 is Blendgos limit.

I actually'd like a wider spectrum

kram! u lie :O u sure that 1000000 isnt the limit... im sure i remember being told that 1000000 = mirror... o well

dont spose it makes a difference

It doesn't really make a big difference, any more, yes.
But if you want "infinite" Exponent, simply use Specular instead of Phong

It *should* make a difference, though: If you have an infinite reflection, somewhere, and DAMN high RayBounceDepth...
If you're able to make out the LAST reflection, there may be a difference

one mil is the mirror thing, so 1 mil shud be the limit

Kram1032 · Post by **Kram1032** » Thu Aug 09, 2007 4:21 am

-.-

even "1" is a mirror, but it's SUCH blurred, that you can't see ANYTHING
(It looks perfectly diffuse)

"infinite" or that, what specular makes, is the ONLY perfect mirror. At least, in terms of blurryness.
However, 1 mil is QUITE perfect - you can't really see a differnce, then, anymore
