Material Editor ---->Noise

[zooropa]

Hello to everyone. I'm wondering where I can found some help, manual, link with some information about parameters of the Noise section. Is there any possibility or any plan to update the VfR manual (more like a full version).

Thanks a lot.

That's the V-Ray manual, ours is just supposed to fill in some additional information that relates specifically to our product(s). A rewrite of the manual is on our list of things to do, and we hope to get to it as soon as we can. The next version that we are working on, includes many changes to our UI, and it adds/changes some features as well, so when a rewrite does happen, it will be for the new version.

Thanks for your fast response.

I have a while looking for noise parameter inside the link that you sent me. I can't find it.

Any help please? :-\

Thanks

Re: Material Editor ---->Noise

I don't know what you're referring to as the "noise section", are you talking about the noise procedural texture?

Inside Bumps for example you can choose:

Acolor
Checker

Noise

Thanks!

Ah, the noise texture. Unfortunately the chaos group didn't provide us with much info about it. Here's what we have:

persistence: float = 1, amplitude(i+1) = amplitude(i) / persistence 
amplitude_ratio: float = 1, amplitude(i+1) = amplitude(i) * amplitude_ratio 
frequency_ratio: float = 2, frequency(i+1) = frequency(i) * frequency_ratio 
frequency1: float = 1, The starting frequency (just like size) 
amplitude1: float = 1, The starting amplitude 
octaves: integer = 3 
noiseType: integer = 0, 0: just noise(), 1: Perlin noise, 2: inflected Perlin noise, 3: marble (with Perlin) 
size: float = 1, scale 
inflection: integer = 0, 1: inflected, 0: not inflected 
mix_ratio: float = 0.5, 0: color1 only, 1: color2 only, 0.5(def.): 50%-50% 
bias: float = 0, similiar to contrast 
color1: color = Color(1, 1, 1) 
color2: color = Color(0, 0, 0) 
color1_tex: acolor texture 
color2_tex: acolor texture 
color1_tex_mult: float = 1 
color2_tex_mult: float = 1 
use_3d_mapping: bool = true

So my suggestion is to just play around with the buttons, and see if you can kind of figure it out.
