Fog Bias parameter test in Vray Material
I did notice this new parameter since the 1.5 Service Pack 1, and decided to make some test. Actually, this parameter does exactly what I need… but it’s quite hard to explain and an image will be clearer than thousands of word :
Let’s say that it quickens the darkening of the fog inside the material, like if it become exponential when the bias is set below 0. If you lower the bias too much, it’ll darken too fast and you’ll have to lower the multiplier accordingly.
The good point of the test is that it doesn’t involve any glossiness nor transluency, the rendering times were relatively low and the shadows of the object just perfect ;)
