Specular material help
Specular material help
I've got a little problem regarding specular materials. I want to create a material like this one: http://elqx.com/indmatdb/inc/imgs/image ... .jpg&s=220
In the attached testscene (R 9.6 file format) are three tests but I don't get such a material.
Can anybody help me?
Best regards,
okazaky

Here's another test with a specular material.
Units: kilometers
sphere 1 size: 73.425 km
sphere 2 size: 124.785 km
sphere 3 size: 198.348 km
every sphere uses the same material.
The bigger the spheres get, the less transparent and the more colorful they get. Is this a bug or am I totally wrong in the way of setting up the scene?

no, that's simply the problem, you have - it's the point, why you don't get a visible colour with cm or m...
Absorbtion is the (amount of light, absorbet per meters)^-1 (= meters, where an amount of light is absorbed)
and you set it extremely low - can't even be absorbtion 1 xD
that would look less transparent, in so many kilometers.
It's simply realism
Example: If you have about 1l Milk, in a bottle, can you see through it?
But if you have that l on a big milk-varnish - can you see through it, then?
Ok, not the BEST excample, as Milk also has SSS... but it should show you the point, anyway.

yes, I know....
actually, ANY object has SSS... so, even a brick has light trespassing.
But it's your settings, that must be completely wrong
I guess, the absorbtion is in 0-1 range + a multiplier...
which Prog which Exporter?
Blendigo has a "Gain" Value, next to several things. It EVER is a simple Multiplier

I see...
obviously, it needs a gain-value, or anything like that.
I wonder, how it was done, by now... as it shouldn't be too hard to request that.
Maybe, you have to also use uniformal Absorption Coefficient? That may act as a multiplier, if it's unused.... -> values like "0" wont give any absorbtion at all
