Hi Folks,
I've spent the day creating a COB importer for Poser 7.
I've got the geometry, grouping, material groups and UV data all behaving themselves, I'm now looking at the actual material values. Does any one have information as to what line in the COB file relates to what Poser material parameter and/or the equivalent in an wavefront MTL file? I've got a fair bit sorted out but I find that I'm now beginning to take guesses and that is probably not good :)
When its done I'll be putting it out as a freebie. |

I'm sure there will be a lot of people happy to see this :)
Only help I can offer you at the moment is:
http://www.caligari.com/download/tsx.asp?Cate=DTSX
But this might be something that you'll want to contact Caligari directly. The devs should be able to help you with specific problems. ;) Keep in mind though that different programs handle materials differently so not everything will have a 1:1 conversion and you'll have to just choose to substitute poser things that you feel would be equivalent.

Thanks, that is exactly what I was looking for.
Now I've got to figure out how to apply the transformation matrices :) |

Task:-
to apply a translation array to an array
of 3D vertex coordinates to produce the
resulting location of each vertices.
Translation array and vertex coordinates taken from
a Truespace COB file.
The text in the COB file looks like this:-

I've uploaded the first beta version to this page (http://www.philc.net/forum/viewtopic.php?p=6897).
I'd be greatful for any feedback. Particularly regarding how to apply the transformation matrices.
Thanks,
PhilC |

Very cool PhilC. :)
I don't have Poser, or I'd test it out for you. ;) |

Thanks PhilC - I've downloaded from work but I'll try to remember to give it a go when I get home. |
