Re: Additional RAL color material

Nice Ralf!
Did you make these up or download them from a library? My company products are painted RAL9002 'Flake Grey' & BS627 'Light Aircraft Grey'.
Are they available, do you know?
Thanks.

Hi Jeff,

It is a selfmade material with HyperShot v1.5.12.
If you want you can edit this material file with a freeware tool: Notepad++

- Open Notepad++
- Open the RAL.bip file
- Now you can change all values. All what you need is the color "base" information:
"base" 0.839216 0.690196 0.458824,


Or an other example: All this colors have a metal coverage: 20% or 0.2
"metal_coverage" 0.2,"

Please have a look:

Re: Additional RAL color material

Ralf - I've been looking for a translator for RAL to RGB. Do you know of a good one?

Hi Dennis,

Excuse, my English language is too bad, to describe this in a correct manner. RGB colors are more like a "chewing gum".
The same RGB color are shown on two monitors: LCD and CRT can be very different and all "Book printer/Printing offices" hate RAL colors. :lol:

An other example is: A Mac monitor has a gamma of:1.8 but a "DOS box" monitor has a gamma of: 2.2
We have created the "Color material" with a Mac ... no problem, but it can be a "bit" different are displayed.
To compensate this effect...we have change the "metal_coverage" 0.2, (The value should be actually: 0.0)

But please have have a look, this is IMHO one of the best sources of informations with some helpfull tools:

Hi Jeff & Dennis,

Now I understand .

Example: RAL 9002 ~

http://www.dirp.cz/en/ral-colour-sample ... ion-to-rgb

R 240 / G 237 / B 230

1 = 256
0 = 1

R = 240 : 256 = 0.9375
G = 237 : 256 = 0.92578125
B = 230 : 256 = 0.8984375


Close HyperShot.
Then you can open with the free Nootepad++ Editor -> HyperShot -> Material Libary -> RAL.bip and add this new material:

	  }  
}

#define material "RAL_9002" {
  surface   "metallic_paint" {
    "base" 0.9375 0.92578125 0.8984375,
    "metal" 0.95 0.95 0.95,
    "roughness" 0.01,
    "metal_roughness" 0.05,
    "metal_coverage" 0.2,
    "metal_samples" 1,
    "ior" 1.5,

If the color is too glossy , the: "metal_coverage" 0.2, value can be changed to: "metal_coverage" 0.0,

I hope you can understand my description.
