Anyone know a good way to fight off the insane look of a flashlight coming from a poser character's "third eye?"

hon if you look in the freebie section (do a search for nostril glow) i cannot remember which member has a fix for this but i do know i saw one in the freebie stuff :)

Cast shadows, or Darken the nostril material.

Traveler and Maveris. The "no-glow" nostril props are at RunTime DNA.

ohhh yah RDNA, gah sorry so many freebie sections so little memory!

Simply choose the nostril node or material zone if in P4 and choose a dark grey-brown color instead of the texture map. Frees up memory and guarantees a dark nostril.

can anyone say why the nostrils are glowing in the first place? we we're discussing this at daz a while back & I don't think anyone could give a reason http://forum.daz3d.com/viewtopic.php?t=17759 cheers Stefan

Okay, I am using P6, and I didn't see a nostril node. However, what I am working with now is sort of a half@$$ed fix. I created a group and select the polys inside the nostril area. (I still have to clean them up, for some reason it is not allowing me to select individual polys, just drag-choosing.) I assigned a nostril material to those polys, and then set the material to an alomst black shade of brown. This appears to have worked, and will probably look okay if I can ever select just the polys I am trying to. I will give a nod to the question posed by Stefan though. Why in the name of the Poser gods do the nostrils glow? It makes about as much sense as a wooden nickel.

It's something to do with the way Poser handles the small geometry (or ssomething *P). Poser 6's Ambient Occlusion solves the problem with no further tweaking necessary, but all the above tips are useful, especially RDNA's No Glow nostrils.

It's amazing what picture gets forced into your mind when you see the title of some threads. I was going to say "stop pointing the flashlight in your ear".

see this thread - they are too small to catch shadows

I thought that the "third eye" was somewhere else. ;)

Well... if THAT eye glows, take the torch outta your @*s..!

If the figures were truly lifelike, the nostril glow problem would go away when the figure reaches age 50. Then... the nostrils (and ears) would look like a grizlie bears armpit..!

lol, ziggie, that can be handled in the hair room ;) In all seriousness, I hate noseglow with the passion of a thousand suns, and the only way I get around it is by, well, positioning either the body or a light object so a little glow in the nostril looks, well, normal. If the light is coming from slightly below the head and off to one side, the radioactive nostrils (kidding) don't look so out of place. Same with lying on the floor, or heck, even standing on your head. That's mostly because 1. I suck at postwork, and 2. most of the workarounds haven't worked for me (although, I'm liking the point lights in D|S, so if the ones in P6 are similar, I'm going to have to sell my kidney so I can get that, too lol)

For a quick fix, see FAQ #7 on my web site. *"can anyone say why the nostrils are glowing in the first place?"* Yep - they're a consequence of how shadow maps work: First, shadow maps are usually blurred to simulate soft shadows. That can cause that small details in it get lost - like nostrils. Second, shadow maps are slightly offset to avoid self-shadowing. This means that shadows are a tiny bit "detached" from the surface that is actually casting the shadow. To fix cause #1, the first thing do to is to adjust the area covered by the shadow map - the : If you're using spotlights, keep the cone angle as narrow as possible in your scene. For directional lights, zoom in the shadow lite cam so that it covers only the things that actually need to cast shadows (e.g. in a portrait, legs don't need to cast shadows). Last thing to try is increasing the shadow map size - this is really the last thing to try, because in contrast to the others, it significantly increases the render time and the amount of RAM used when rendering. For #2, you can often decrease the shadow bias of Poser's lights. The default is playing it safe, so you barely ever get self-shadowing in Poser. Quite often, you can safely lower the bias without any unwanted side effects. Or, the quick and simple way out: Use raytraced shadows or AO.

thanks Stewer :) is there such a thing as glowing ear syndrome?..I would've thought the hole in the ear about the same size as the average nostril (forgive me if that's a daft question) btw,I was at your site a couple hours ago(very handy faq for double checking things) & the links for 'FAQ on ShaderMaker.' & 'tutorial on math nodes in ShaderMaker' are dead,that's the first I've heard of shader-maker & looked like it was worth a look Cheers Stefan

The ear holes are being shadowed by the whole head, where the nostrils are being shadowed by the much smaller nose - that's why you usually don't see this in ears. The shadow map contains the position of the objects that cast shadows, not the ones receiving them - so shadow map problems usually depend on the casting objects, not the receiving. -(another) Stefan

Dunno about that, but you might be interested in this thread... see post #3 (don't be drinking a cup of coffee at the time though).

I set the nostril material to dark brown. Seems to work.


xantor posted Thu, 12 May 2005 at 11:53 PM

Quite a few other programs have the nose glow effect, lightwave 5.5 and imagine are just two of them, so it isn`t a poser only problem.
