this is probably an old question.. but can someone tell me why when I export an obj from OPS, import it to max, export it from there as an Obj and import back to Max that the smoothing vanishes? I don't even need to make any changes to it for this to happen (Max3.1). It's making working on models really quiet impossible.

Yes, I know I've asked alot of questions recently.. lol

Thanks guys

I'm not sure, but I think this is either a bug with the conversion plugins or it has to do with the vertex order getting confused. Max "sees" and "builds" in triangles only. OBJ files can contain both quads and tris. Since, smoothing depends on vertices, a lot can go awry when importing quads into Max. The best way around this is to export the object out with just texture coordinates checked, then import it back in to Max, and finally export it out with texture coordinates and normals checked. In essence, you have to Maxify the object.

Hey, how come people are still using OBJ files? I thought OPS had switched to VRML support?

well, the VRML is ok, cept for that I dunno how to make it export from Max at the size I imported it.. for me they appear back in OPS about 50% to small, also I'm not sure on the texture part either, but yes, exporting VRML does keep the smoothing.

If anyone can explain those 2 vrml points I and I think others would be grateful

Nat,

Try to Reset Xform (transform). That did it for me when working with VRML and my wanting to keep the size correct.

And for texture maps, as long as your part is textured, upon exporting it as a VRML 97 file from Max have NORMALS checked up top (I use no other options up there), and down below where it says Bitmap URL prefix, UNcheck that box and it'll use texures the usual way, from the textures folder.

Also Nat, regarding smoothing... do NOT use OPS to export the LODS because for some reason AC3D won't open them. I used hippies extractor (the new OL one) and extracted the A10.sm file. I found the lod (lod 20) and imported it into AC3D. Go into Vertex mode and in the Vertex menu go to the bottom and select "Remove surface only." Then go to EDIT menu and select UNDO. Save the LOD (just overwrite the old one), rebuild the SM, load it up into OPS and you should (and I did) have a new smoothed part!
