Unknown artifact I can't get rid of

in Daz Studio Discussion

I've run into a recurring issue, and artifact, that I've searched out but can't find the solution for. It looks like a lighting blob but remains no matter which lighting setup I use, or HDRI. Please take a look at the screen grab and tell me what you think it is. I've moved the model around, rotated the dome lighting, and dropped in an actual set, but that shape remains. It might be red, blue, black, or whatever, but it's always there.

    It's that red thing on her heel. That's not "marker."

    Check surface of Legs... or set texture maps in Base Color, Translucency Weight / Color to None, see if there's any change

    This character is the HID Emmy DAZ+ Exclusive for Genesis 9. Also, this pic was snapped from the insertion point a 0,0,0. I would think the surface map for the skin would be good, but who knows? Anyone? When it comes to playing around with Genesis 9 I'm out of my depth. I'll play with the Base Color and Translucency Weight.

    I played around with surface settings and changed the HDRI lighting again, to no avail. Attached is another screenshot to show that the spot doesn't change. As noted before, When I move the character around, away from 000, the spot remains. Are there any DAZ representatives watching this that can loop in the HID creators here?

    What are your render settings?

    I remember seeing something similar when I was experimenting with different settings, but don't remember any more, which setting it was.

  • PiquantPiquant Posts: 323

    Attached are my settings. I've seen something like this too, but that was because I was rendering a character that was too far away from 000. This one is on 000, or very near it.

    Her default size is 90.6 %. At 100% that tarnish goes away. If I apply another character to that exact location, replacing Emmy, that tarnish remains. However, if the new character is taller, it goes away. I do not want her to be bigger. She is charming at her default size. This appears to be a technical problem within DAZ Studios.

    Sorry, nothing in the settings jumped out.

    Please give the figure some clothes, black bars are not an aceptable way to cover.

    I tested with both GR / PB with this char., haven't seen any similar issue. You may attach you scene file in here that we may check.

    The issue comes from that Vellus shell, if I set Offset value to 0.010, the issue is gone. So it's a common issue from a geo-shell...

    Geo-Shell. Hm. Thank you, all, for your posts in reply. I've picked up some knowledge from these posts. "Crosswind," you're post fixed the immediate issue, but I wonder if the geo-shell creator can update their product to better manage this issue moving forward.

    Yup, technically they can but practically they have no way to cover all testing cases. One important point is: there's no 100% perfect product in 3D world, so that's why we better learn how to resolve these issues by ourselves...smiley
