How do I turn it off...after a couple years, it is FINALLY  annoying me :(

Never heard of "backface culling" so I Googled it. It seems to me something to do with Open GL rendering. I always use software rendering in Daz Studio.

Following link to a couple of forum on the matter. Hope it helps.

If you notice the hair in this one looks slightly transparent making the layers underneath visible.

Ah! Now I see what you mean. The same thing happens to me. I have found that it is because of the transparency map applied to the opacity setting under Daz Studio surface tab. For products like hair (and eyelashes) a transparency map is common and you can't not use it.

When your viewing your scene it is in Open GL mode. But when your rendering your scene, Daz Studio is set for software render as default. Anyhoot what you've shown shouldn't show up after rendering. I use the default software rendering (not Open GL rendering).

Note: Transparency maps create really long render times if you have lights with shadows turned on. I've once had my PC stalled for 5 minutes while rendering eye lashes. The annoying thing was it wasn't even a close up portrait. Sigh!

actually i don't use DazStudio for anything but setting up my scene and exporting, it is just annoying. I really wanted to turn it off in the display settings, but i fond no way to do so. Ah well...

thanks for all the help (;

Turn off backface cull in the program you are exporting it to. You havent said what program you are exporting it to so cant help you on that part. you may have to select the parts or polygons of the model individually to turn it off as well as is the case in 3DSMax.

this id directly inside DazStudio. it has EVERYTHING to do with the way DS displays stuff. It isnt fatal or anything, just agrivating. I export to vue with no problems, as Vue does not utilise backface culling.
