Okay when I render my model I get this weird looking render but looks good in preview. Checked the mapping and it is correct. Can anyone tel me how to fix?

what did you model it in ?  some of that could b non-planar polygons or flipped normals .

Poser does not like n-sided polygons (n>=5). I always use UVMapper Pro to triangulate anything that's not a tri or a quad.
UVMapper Pro can cneck for degenerate and non-planar facets and fix the problem by triangulating them. I'm not sure whether the free version of UVMapper can do this too.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter

I have UVMapper Pro but could not figure out how to check for non planar facets or degenerate ones.

It's in Tools->Facets, if you chose "Concave" itl'll scan for concave facets and triangulate them as needed. Same for Tools->Facets->Degenerate.

Doing as suggested made it worse

Weld or Split vertices in UV Mapper Pro maybe?

If welding or splitting the vertices doesn`t work then it looks like some of the polygons are reversed.

I know none are reversed due to converted it to double sided at one point to see if that fixed it. Here is a render of it in D|S it is not as noticeable there.

Wish to thank Khai for helping me fix this. Easy fix is to go into the Material room, select texture and click on Normals Forward. Here is a preview. I am working on some textures and remapping.

So it was reversed normals, as I said.

Quote - So it was reversed normals, as I said.

no, it's a double faced surface with a zero thickness.. and has been known about since Poser 5...
the fix in 5 was add a small amount of displacement, 6 and higher have the Normals switch.. Most render engines can allow for it.

and I'm suprised at the names in this thread that did'nt spot it.... as I said.. it's been known for years...


xantor ( ) posted Fri, 30 May 2008 at 2:08 PM

That must have been the same problem I had with the 3dsc fairytale coach (but I don`t know how it got double faced surfaces).


kuroyume0161 ( ) posted Fri, 30 May 2008 at 2:51 PM

Hey Khai, I'm callin' you out!  (just joking) :D

I have rarely (if ever) encountered this in Poser so it didn't register but it is mentioned in B L Render's book.  Really, without the obj file to examine it could have been ngons, normals, degenerate polygons, double-sided polygons, need for welds/splits (which is a common problem resulting in odd shading results), and so on.

Hopefully that solves it! :)

nyguy:

i'm surprised that  svdl didn't mention that he has a script that changes all the normals forward in a scene at once.

Well I had just uploaded it to my website and it is live for downloading. I will be working on textures later right now I gotta play with my son for a few.
