I tried to set up a test to illustrate my problem, but now im even more confused. Basically i want to use the bias function to pull the dirt down towards the ground. But its giving me weird results. Right now, #3 looks good, but im confused by 2.
As you can see 4 has a large bias value (10) and is introducing color black. (BTW youre looking at a vraydiffuse channel, so where does black appear from?). #3 works fine with the bias value of 1, but 2 is producing errors and you can obviously read the segments.
Is there something wrong with 2 (why are you able to read the segments, while #3 has such a smooth transition)?
I want to be able to control this bias by pulling it as much as possible in the Z axis, so i thought, the larger the value, the larger the ratio is between Z:x and Z:y, but while it works good with walls, whenever i get an arch, i get errors.
It seems kind of normal; it was mostly designed for bias values smaller than 1.0. I have to try and reproduce this here though so that I can see what happens exactly.
It seems that distribution is causing the black spot to appear. But in my original example, the distributino helps me get rid of the segments in the 3rd sample.
