Problems with punch out then exporting obj - Polyloop

Schurbys · 6th June 2004, 21:44

I have been creating trim for a building. First I create a cube and then punch out a design, but when I export it as a obj it doesn't retain the pattern as created. But if I cut an edge it saves just fine. Also if I save it as a 3ds and bring it into Poser or Bryce and save it out as a obj it's just fine. Screenshots from Amapi, Bryce and UVMapper Pro. Can someone please tell me what I'm doing wrong?
Thanks

Hello,

it seems to be the common Amapi => .obj Problem. Amapi dosen't triangulate face's with more than 4 points automatically. Most other programs are not able to understand the resulting file. To solve this problem you habe to double click your objects in Amapi and than select "triangulate faces with more than 4 points". Afterwards you can export to .obj and everything should be fine.

Thankyou for the help. This has stumped me for 2 days and your suggestion worked fine. Now to finish the project... :D

Your other choice would be to use 3DS which can handle n-sided polys. There are two OBJ formats these days (one for 3 and 4-sided polys, and one for n-sided polys). Not many apps understand n-poly OBJ, yet.

Shonner : where did you see that about the OBJ ? I never heard about that ! (it make me understand some old problems.. huh ! : ))

Amapi 7 and Maya 6 are a few of the newer modeling apps that can work with OBJ models that have n-sided polygons. But 99% of modeling apps still only work with 3 and 4-sided polygon OBJ models.

3DSMax do too ;)

U3D is supposed to be the 3D format standard one day. I wish people would leave OBJ as it was, rather than creating another version of OBJ that is not standard.

Huh ! I never eared about this 3D format ! I think it will hard for it to become a standard if anybody know it... :P

MICROSOFT, HP, DELL, TOSHIBA, AUTODESK, INTEL, and various software companies will be supporting it.

Thomas · 13th June 2004, 16:32

oh, this this -new- format that all the industrials will support ? but if I remember, it will be a web based format...
By the way, anything for us.. (Dell, toshiba, HP... which software are they creating ? ;)

The 3DIF forum may have some updated info about the universal 3D format. Macromedia might not be as involved as most web developers would have hoped for. The format will work with 3D apps, web browsers, PDA's, TabletPC's, game consoles, etc. Anything with a USB/fire-wire port and video screen basically.
