Hi all.
I'm rather new to POV (about 1 month) and I am trying to do soft shadows.
For that, I used the area_light option. This softens the shadows, increases
the computation time, but generates a very "grainy" shadow.
Is there a trick to avoid it ?
To see the result of my first tries, look at :

(the texture on the wall is only a white pigment, no normal or other
effects...)

I'm not noticing the 'grainy' look there ... but I know the look you
mean. I found that increasing the number of lights in the area light
will give a much less grainy shadow but doesn't increase the render time
considerably.
Cheers!

But only if you use adaptive supersampling (which you should, of course).

It is not to divert you from news.povray.org , of course, but
Do you know the french speaking POV-Ray group?
news://news.zoo-logique.org/3D.Pov-Ray
In your newsreader count/server configuration you must check "ouverture de
session requise" and
enter a user name : zoo
and a password : entrer
You are welcome :)
