Glowing Eye Socket

[Midnight Arrow]

‌

‌

Blender 3.2, exporter v1.6.2.1027.

Using Zelara 8’s skin settings, when the face is lit from the side the eye socket in shadow glows. The importer isn’t creating a volume node for it. The texture maps themselves don’t seem to matter. The one on top uses Zelara’s maps, the one on bottom is another skin with Zelara’s settings applied.

And how this compare to iray ?

I mean, you assume that the iray material is right that may not be the case. If the iray material is wrong to start with then it is converted the same in blender.

The eye socket has a volume as expected. But it looks like the figure uses a cutout opacity mask that may be confusing the exporter.

Again, did you compare an iray render ? Because I get the same in iray.

There’s nothing I can see.

Here’s mine in iray. Test scene included zelara.duf. You have to use the same lights and camera to make comparisons.

I tested and do see the same behavior in Daz.

However the issue remains, that if you add the missing volume node in Blender the problem goes away. The importer should fix it by accident when converting the material information stored in the MDL surface. Why does no volume node get created?

‌

[Alessandro Padovani]

As for materials the importer is designed to mimic iray and this is what it does. In this specific case iray ignores the volume because there’s a opacity map. You can get the whole material tree by unchecking “prune node tree“ in the global settings.

There is nothing to fix here and this is not a bug please mark as invalid.

‌

note. Unfortunately it is not uncommon that PAs don’t understand the iray materials also because iray is very flexible and allows for a number of “non-pbr“ exceptions so you have to know how to use it to make good materials. This results in poor materials that don’t work fine in some lighting conditions as in this case.

it is better as invalid since this is not a bug
