I have this problem with at least two models that I'm using. I have tried switching off the smooth poly option but can't seem to get the windows to render properly. Does anyone have any suggestions or insights into the cause of this?

n-gons? If the windows are 'holes' punch through a single polygon making it have more than four vertices, that might cause the problem. Poser does not really support them (but even CL has released figures with objects that have n-gons - go figure).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.

Have you tried it with the Poser 4 renderer?

Usually this sort of thing is just as bad in both versions. Poser just HATES facets with concave sides, and a punched window is almost guaranteed to involve some concave sides. Poser tries to bridge over the inturned edges, which gives those "bracket" thingies. Too bad, because it's a pretty house!

Remember that issue that Marforno was having? It was caused by L-shaped polygons, I think. His models look great when you render with the P4 renderer, but you get weird artifacts in the window corners when rendering in Firefly.

radym77, You were right, it renders fine with the P4 render engine. But does anyone know why firefly creates this problem? After all, isn't firefly supposed to be an upgrade? Not to bash CL or anything, but what are the differences in the two engines? Anybody know of any links or threads that would help?

Triangulating the mesh might help. Of course, it might also make things worse.

Randy, you're right. Here's a quick test using a pure L made in Amapi. In P5, using both renderers.....

P5's Firefly renderer is derived from the Tempest render engine used in PiXELS 3D. It's a completely different render engine that the old P4 scanline renderer.

I find it amazing that the CL team got it to work in Poser at all. It wasn't really designed to handle meshes this small ....

there is an answer.. those are caused by N-Gons (poly's with more than 4 sides). if you have a modeling program, (and the inclination), goto the corner of each window and connect the corner vertice to another with an edge. this will "fix" that corner. it's a better method than tri'ing the model.. (cuts the polycount from the tripled amount to just what you need)... I did a mini tute for tS, (applicable in any program that exports to OBJ format), here - http://www.renderosity.com/messages.ez?Form.ShowMessage=1895179 hope that helps explain the problem.. the poser 4 render is slightly more forgiving than firefly.. but not much... hth!

You'd only need to triangulate the problem areas, I think, but I agree.

the poser 4 render is slightly more forgiving than firefly.. but not much... It's certainly more forgiving with regard to double-sided polys. :/

Great! This is just what I needed to know. The original mesh is not mine but I'm going to go play around and see what I come up with. I only hope the original author will respond to my e-mail and find this thread. Thanks, L8tr
