Any modellers out there know how to avoid this sort of problem when spline modelling for Poser....works great in anything else but Poser is a bitch for this sort of result. I've tried everything I can think of in UV Mapper Pro & starting to think that box bodelling is the only way to get clean geometry into Poser. Cheers Brian

Making stairs with a spline modeler is a bit like fishing with a sling shot. You can do it, but it might not be pretty.

You could export that to Wings3D and merge the tri's and make nice quads without mussing the shape. And you can map it in Wings too. It would be a good way to get the hang of wings, you might end up using it for more of the modelling.

A couple of hints: Those curves (chamfers) between the risers really don't need to be so curvy unless you're going to zoom in and show an extreme closeup of those particular surfaces. Poser just loves to round things off, which is a problem in other circumstances but a virtue here. Probably a three- or four-slice curve will do just fine, which will give you much more controllable tesselation on the side of each step. Also, if you build the side rails as separate pieces (which will end up as separate Groups in the result) you can avoid the tesselation on them entirely. They can be plain old quadrilaterals.

Wanna stair? Clean condition, hardly used. I'll mail it to ya.

Thanks guys, seems to be solved, the heavy chamfer seems to be the main culprit. Thanks for your time. Brian

obm890, that set of stairs won't work correctly in Poser. It's got 6 sided faces.

...he can correct that in about 90 seconds if need be...

Nope. Only quads in that model, there's a short edge on the side face at the nosing of each step, it connects those chamfer lines. Hard to see in the pic, but it's there. And in my experience, poser deals with more than 4 sides just fine, provided the face is a simple, roughly circular shape (L-shaped or U-shaped will no doubt cause problems). In hundreds of models I've never once had a problem with an n-gon in Poser.

Clothing tends to be a different story with anything over a quad.
