Subject: why is it rendering like this?

I regrouped the antenneas off of the buzz alien from the 3dcc. Then saved them as props. I then exported them as objs and uvmapped them so I could apply a texture. Brought the new objs into poser and put them on the default dudes head. The insert picture is an actual render. Where is that black whole coming from on the antenna? The larger background picture is the display window set to shaded texture. As you can see that black spot is not there. It only shows up when I render. Could it be a problem with the obj?

Hopefully someone here will correct me if I am wrong about this, but I think the black spots are caused by the polygon norms in that area being reversed. You should be able to hightlight the area using the grouping tool and than click on the reverse group normals to fix this.

heyas; actually black holes come from 'degenerate facets.' when you're remapping the antenna in uvmapper, press... i think it's "insert" to 'fix degenerate facets.' (check the hotkeys.) another way to avoid these is to use an obj pointer, instead of embedded geometry. (when you made it a prop, poser just embedded the geometry in the pp2. you can make it point to an obj you export, instead. if buzz happens to have the antennae as separate body parts, you can actually just use a chopped cr2 that deletes everything but those parts.) reversed normals appear 'invisible' or 'inside out' in preview, but render normally (usually).

Kewl! Thanks for setting me straight blood. :o) Heya blau, ignore what I said and go with what bloodsong said she rules when it comes to this sort of thing. (She is also very modest and will tell you otherwise. But visit her sight and see all the cool morphs and figures and stuff she had cranked out and you will know better.)

There's another thing I've found that can cause the black spots - co-linear facets. If the first three vertices of a facet are all on the same line, any program that tries to use them to determine which way the facets if facing won't be able to do so. FWIW, Steve
