'Bright' intersection

gioloi

Hi all.

I have this issue using AOA Advanced Ambient Light and some clothing objects (not all).
It happens with bare skin, too.

The picture explains better than my words:

Since often it is impossible to avoid totally the intersection between objects, is there a way to avoid at least that annoying effect?
Note that it doesn't happen with the shoes, which intersect the floor much more deeply than the jeans.

Try increasing the shadow bias, it should help.

There's no 'shadow bias' in the AOA Light. Do you mean 'AO Bias'?

I believe AO Bias is the equivalent for AoA Ambient Lights.

Excerpt:

• AO Bias - Like the bias setting on other lights, this offsets the occlusion shadow calculation a slight distance away from the surface to avoid self shadowing artifacts. Depending on other settings like Hit Sides - Both and AO Cone Angle, The Advanced Ambient Light can be a little more sensitive to bias than other lights. If self shadowing artifacts do appear either increase the bias, apply Sub-D to the geometry or try using Hit Sides - Front.

It was the Bias. I have to reduce it, not increase, but you put me in the right direction. Thanks. :)

Unfortunately, reducing the Bias too much creates artifacts with stockings in other pictures, so I have to find a compromise. Can't eliminate everything. :(
