Title: Noob, white noise and starting to feel a slight DESPERATION Post by: Mune on March 30, 2013, 07:34:10 PM Can someone point me in the right direction here?
So I managed to remove the black noise from an image at an earlier point, by reducing the RM and the SL, as suggested in many tutorials. You know, as a beginner having something like that work out feels GOOD. But I am facing white noise now, and I can't tweak it away..the entire picture is noisy. What am I doing wrong? So so wrong .... :'( Title: Re: Noob, white noise and starting to feel a slight DESPERATION Post by: cKleinhuis on March 30, 2013, 07:38:03 PM so, hello and welcome to the forums
sorry, with your description we cant help you, about what are you talking ?! what means RM and SL ? do you talk about fractals ?! 2d ? 3d? photography? global illumination rendering ? i have no clue what you are talking about, and the way you are posting you are seeming to me like a spam bot, please elaborate !

I am using the Mandelbulb 3d...with RM I meant raystep multiplier and SL - stepwith limiter.
