Create booleans in Bryce 7 and import them into Poser: the normals are messed up.

I wanted to create a wall with a hole and more complex objects.
I collapsed the boolean object in Brye and exported it as an obj-file.
Imported it into Poser (7).
Although the rendered images look not too bad IMHO, it's quite annoying.

I treid the option Make Polygon Normals consistent, but it doesn't work so far.
The Poser group editor is a bit tedious.

Is it a bug ??
Is there a way or a tool to fix this issue ??

Thanks in advance.

See screenshots.

Here is the rendered image - not perfect but acceptable.

Booleans are evil and should be avoided - basically, they can create the kind of polygons that give Poser conniptions. long thin triangles and NGons.

You can try adjusting the crease angle in Poser or load to uvmapper and split vertices.

I've always heard booleans are the work of the devil, yet I've heard of a book called "Poser Secrets" which IIR claims that this is a myth and booleans work fine in poser?. I haven't purchased it but wondered if anyone has and whether I'm dreaming, i think it was also marketed by SM but i'm not 100% sure.

Try using the grouping tool and select the offending normas and then click reverse group normals. Though sometimes with is more of a pain than having the normals backwards.

Attached Link: Groboto

My understanding is that Poser doesn't like long thin polygons of the kind shown in your 1st screenshot - a model that contains these will have shading issues. So boolean operations that result in this kind of topology will be problematic but booleans that have a different topology will work fine.

I found a useful and cheap modeling app a while back called Groboto (see attached link) which is based on using primitives plus boolean operations. I've found the interface takes a bit of getting used to, but it's quite addictive, can make very complex shapes and can auto-generate quad meshes with pretty good (though not perfect) topology at varying resolutions. The helmet in the attached pic was 90% modeled in Groboto - some spheres and other default primitives plus several boolean operations. It also auto-generates UV maps based on the 'patches' formed by the primitives. Might be worth a look?

I use a lot of booleans in my modeling for poser, so far I haven't encountered too many problems. There's one thing I always make sure though, after I'm done with all of my  boolean operations, I always triangulate my model and save the triangulated version as a new file, just incase I want to go back later and change things. Poser will now import the model just fine, no matter what crazy kinds of booleans I've thrown unto the model.
