I hate my Mac

.
Man i must buy me a new PC!very soon!!!!!!!!!!!!!
Thanx Ono.

Ps: Ono could we make an Mac-fund on the Site?

Nice features, thx alot

I wonder if using specular reflectivity spectrum instead of nk-data reduces render time? I havent tried it so far, just asking

I'm not sure Deduese, you'll have to try it

Ono... a quick question:
Does the brightness of a Oran Nayar color should be max 0.8 too like for diffuse for optimal speed?

Code: Select all

<material>
        <name>plastic</name>
		  <oren_nayar>
				<albedo_spectrum>
                <rgb>
                    <rgb>0.769 0.384 0</rgb>
                    <gamma>2.2</gamma>
                </rgb>
				</albedo_spectrum>
			  <sigma>0.33333</sigma>
		 </oren_nayar>
</material>

Thank you Nick !

ZomB:
The albedo for diffuse, Phong, Oren-Nayar etc.. can never be greater than 1.

The closer it is to one, the slower the render will proceed, *if* light is trapped and bounces around a lot. So it really depends on the scene.
As a general rule I wouldn't set the albedo to more than 0.8 or 0.9, however.

That's just an example, the albedo spectrum can use any kind of spectrum - RGB, uniform, tabulated, etc..

very confusing

< typical>

Can't wait to get home to try some "clay" renders with Oren Nayer, thanks Ono!

EDIT: forgot to mention - thanks for the colored metal - I (and many others) were using Tinman's converter to get those in the past - having it built in is much better, no .nk file to lose, keep track of, etc.

Thanks Ono!! Now maybe I can do a decent brass texture.
