Need Help really quickly!

Ok, so I got a call for a job interview the other day, and part one of the interview is a 3D test. I have to make an object that they chose and of course, after years of doing 3D, I had to come across this problem during the test. I have until tuesday to finish, and today is Friday...and just turned to saturday(hit 12 oclock while i'm typing hahaha).

My problem is, when I export to .obj, it messes my geometry up. I made one whole model and then encountered this at the very end. After searching for hours, I realised I was just burning time, and figured it would save me time in the long run to start a new model from scratch, and what do you know, its happening again.

Heres an example of the newer mesh.

For some reason it won't let me post pics.

Looks like its just picking the wrong direction for your hidden edges. You could use a "turn to poly" modifier and turn the number of edges to 3 so it will force the hidden edges to be visible. Then export and see what it gives you.

You could also try using some of the other .obj export settings/presets if you're on 2009 or higher. Or use the Guruware obj exporter plug-in for lower versions (same thing, was included in 2009 and up).

Hmm, it looks like you used smooth groups so that kicks my first idea, figuring if you didn't it was creating weird artifacts. When you go to export in max do you have it set to quads or tris because it looks like it's forcing it into tris. that's all I can think of >.>

don't use the inbuilt one - i agree w/ vig use the guruware obj exprtr/importr...

good luck mate !

I am using quads, but I have tried poly too. I will try the guruware plugin now.

I'm using Max 9 for the record.

Guruware didn't work. Same thing.....

Have you tried uv mapping it with a quick planar map?

gannonroader

no, I will tho

Ghostscape

it looks like its connecting up your verts (which are in the right spot) in the wrong order?

Triangulating this before export didn't fix it?

I agree with everyone else that you should get the guruware .obj exporter it works a lot better than the max one.

And of course if you haven't already Reset X-Forms because that is the magic fix shit button

renderhjs

check exporting the OBJ with polygons and not quads or triangles. Also make a copy of your object and convert that one to a mesh before exporting, see if it helps.
