SSS faceting issue

[rohandalvi]

Hi,

This is an issue I've faced before. If the density of the SSS is high enough you start to see the polygons. My solution is to usually keep the polygon count high enough till the faceting is not noticeable. But can this issue be solved.

yeah i've noticed this for a long time as well. would be great to get fixed so that we don't have to subdivide into oblivion

Yep, this happens, but honestly, I use SSS (both Specular and Random Walk) every day almost and have never encountered it.

Is it only if you have a ridiculously high 'density' value ?

I would prefer it not happen at all. At any values. Which is why I am hoping the developers will take notice.

Is there any update/news on this issue? It makes scattering based skin shaders practically unusable when you dont up the geometry count really high (or subdivisions in DAZ Studio, which slows down the viewport immensely).

I haven't tested it but on my projects, I recall only seeing it on high density values.

I can only speak about the DAZ plugin, but even if use density values that are just high enough to give realistic skin results, the faceting is clearly visible. I can somewhat counter this by upping the subdivision levels to a very high amount but it makes the viewport extremely laggy when i have more than 1 or 2 characters in the scene.

Here are 2 examples of a Random Walk material and a Scattering one:
