I have a shirt I need to reduce the vertices in, its too large, how can I do this?

I'm not quite sure what you mean by 'too large'. Too large in physical size? Or in file size? The only way to reduce vertices is to open the mesh in a modelling program and remove them from the mesh. But it would be difficult to do this without destroying the shirt. If it's too large physically, you could try to 'smallen' it with magnets. mac

its too large file size because of so many vertices, it takes longer to render in poser

OK. I see. The only thing you could do is to open it in uv mapper and resave it without the normals, which Poser doesn't use. That's if it actually has the normals in it. Other than that, I don't think there's much you can do. mac PS What size is it anyway? I mean, is it THAT big?

camelot77 ( ) posted Mon, 01 September 2003 at 6:36 PM

19 mb, without normals 14 mb

Oh well, you saved 5 MB anyway. Not bad. mac

There is a poly reduction tool that reduces the file size by reorganizing and reducing the vertices. Its one of the best I've seen.

By the way, vizup likes .wrl files (VRML) so I used a program like Crossroads or 3d exploration to covert from obj (or whatever) to one of the vrml conventions then use Vizup to reduce the vertices. After reduction, I converted back to .obj.

WOW! Thanks :)

Vizup is kinda spendy. Amorphium has a reduction tool and so does Metasequoia (but I think those are poly count reductions not vertice reduction). Most high end modelers have some sort of tool built in. Happy experimenting.

Try QSlim which works with .obj format files, although it leaves out materials and groups. You may need to load the source file zip to get the ReadMe with the usage and command line parameters though. Bill

Just a heads-up, when I was researching the .obj file format for a program I was working on, I found that the Crossroads program outputs some really bad .obj files (I never recieved any response to my e-mail(s), so I don't know if they fixed it since then or not). I don't recall the specific problems off-hand, but they were of the type that kept most any other .obj reading program from reading them.
