Actually in your examples, both caps are displaying irregular phong shading, just the top side is not quite as obvious as the bottom problem.

want the OBJ? no it has no error. sorry.

is it always a cause of head meet wall round here?

I didn't say anything about N-gons or triangles, in the example I gave I had tris and it displays correctly.  Since you fixed your own example with a bevel, it should be pretty clear that the way Poser displays phong shading (default 80 degrees) is looking at your geometry, seeing some angles that are less than 80 degrees, and applying phong shading to them in ways that you don't expect (or vice versa).

the OTHER end has not been beveled. but shows no sign of the error. please explain that.

sorry for the caps. I wanted to emphasise that point. both ends should be affected but only 1 is. I can reproduce this easily,

my test OBj's have been into UVmapper, trueSpace, Silo, Hexagon. no errors, and the OBJ's exported from each show the SAME error in Poser.

Quote - MagnusGreel: The problem is a mesh error before export - optimise the mesh and disconnect the end caps before export and it will be fine.

you sir are missing the point.

go back and read my posts. all of them. including the ones where I point out ONE END IS PERFECT THE OTHER IS NOT.

now. please explain that. by your reckoning BOTH ENDS WOULD BE AFFECTED AND NEED THE CAPS DISCONNECTING.

Quote - I don't think this is any kind of glitch or bug, I think this is just the topology of the cylinder being exported.  You'll find that if the caps of the cylinder are modeled such that you avoid vertices that share more than or less than 4 edges on that corner, it will display correctly in Poser.

Quote - Looks like you have a single vertex normal that is wrong. Not the whole polygon, just that one vertex.

Try exporting without normals. Poser doesn't need them and will recalculate them itself.

The only reason to actually supply vertex normals is if you want the object to be shaded like it is twisted (sort of like a bump map effect). That's how it is rendering.

removing the normals had no effect. the artifact remains as shown.

now lets consider this a second. in the posting above, the cylinder is identical at both ends other than the X/Y/Z translation of points (up/down basically). no extra vertexes, faces etc. one end renders perfectly, the other has a pinching artifact.

but to correct said artifact I microbeveled the affected end as shown.  the other (top) side is unchanged.

there be a glitch in the code here.. how do we file a bug report to SM?

same cylinder OBJ imported twice, one rotated 90 degrees and moved over to 1 side to allow it to be seen.

the artifact keeps it's position on each cylinder.. it's not display based if that's the thinking...

Confirmed. it's happening even to completely Quadded cylinders, but only at 1 end each time.

Images follow

erm guys?

I think we may be looking at something else here.
I just brought a cylinder in and got the same error as first shown.. on one end. now, both ends are identical in layout and vertex count, so one end having the error does not make sense.

Quote - Well, if the ends are n gons (polygons with more then 4 verticies, then there's your problem right here.. for poser you need to use only 3 or 4 point polygons.

If it was me, and you only needed a cylinder, why not just scale and use the included one in poser already?

not quite true. you can use an N-Gon on the end of a cylinder right there without an issue. remove the center Vertex and let it be a 5-16- whatever  sided N-gon and it'll work just fine.

trust me. it'll render just fine.

Expressions are hard!

which is why 99% of the poser images in the gallery have no expressions.....

Quote - I confirmed with the Poser team - this is not a legit offer.  :)

so....no chance of price matching then? ducks
