the screenshots are of a model im working on in zbrush… i have some weird errors popping up in the geometry… and holding shift and clicking doesnt help to smooth it out…it does not get rid of em… the screenshots will show… 
Somehow those polygons have become flipped. That’s why the smooth brush doesn’t help. If you activate Tool>Display Properties>Double, the holes should disappear.
Is this an imported mesh? I recommend checking the original import to make sure that all of the polygons are aligned properly. If it is something that did indeed happen in ZBrush, you would need to use your other software to flip the normals of those polygons. It looks like your mesh density is still low enough that this would be easy. You should also be able to go down to the lowest subdivision level where they are visible, export that level, fix the polygons, and then reimport the mesh into the same level.
mesh density is around 6 million polys… so no… it isnt low… and yea … its already on double… i tried using the smooth brush on both sides of the geometry… and the original model was only like 3000 polys… 1600 polys… just smoothed to level 7 … that screenshot is jsut the arm… but theres alot more to the model… those weird things start appearing around level 4 on that spot… u only see like 3 of them though…
if i were to export that level… i could actually reimport it back and keep the original beginning levels… and still have the detailed 7th level? cause im doing this for a low res displacement or normal map for game character… or is there a way to load to seperate models and generate a normal or displacement map between them… cause i only know of going from level 1 to the highest to generate em so far
As per the message at the top of the Q&T forum, what are your system specs?
amd athlon xp 2400
2.0 ghz
gig ram
geforce 4 ti 4800
shit … im an idiot… when i brought back the hidden geometry for some reason the problem went away… but thats weird cause it was visible on lower levels… i dont know…
anyway… i got a better question… if u wanted to generate a normal map or displacement map between 2 models created totally independently of each other would u be able to do that in zbrush?
How on earth do you manage 6 million polys on that spec lol. Infact do you even need 6 million. Im finding 2 and a half million sufficient.
because thats just 1 arm… not the entire model… that part of the model is nothing
