I never used Poser 3. I would do a seach on My Computer for the file name and .rsr ... My 2 cents Joat Mon

I read somewhere that when making conforming figures, it is best to make the joint parameters a little 'off' the conformer base figure. I'm no pro at it, but have had to do a little tweaking myself.

I would suggest looking at the .obj file.
Make sure body parts are correctly named. I would open it up using a word processor. Search for the word 'hip'. Make sure the names are correct.
For expample:
hip
NOT Figure1_hip....(or something else)
abdomen
lThigh
rThigh

When I've done stuff to .obj files, after exporting from Poser, the names sometimes get screwed up. I'm not sure how to do it without scewing up the names. I just go back and correct them (as the models I build usually only have 6-8 body parts).
Hope my 2 cents help.

(following the thread)---
I've been using gmax for making models. For those who don't know, gmax is Discreet's (Studio Max) approach to tapping into the game tweaking community.
Currently, there is only a beta (?) plugin to import and export Quake III stuff (levels, characters and objects).
If Curious Labs is going to release gmax plugins then LOOK OUT! Modeler heaven!!!
Please let it be, please, please....

Now how will I sleep?! Jeez - No kidding! I hope it's Poser 5. :')

I'm not talking games. I make poser conforming figures (clothes) and props in gmax - then export them as QIII models - then import into MilkShape - then resize and export as .obj files. I also use UV Mapper, Detriang and poser's grouping tools to finish them.
No kidding - if you know how to use max (there are plenty of free tutorials on the net) you can make some amazing stuff for cheap.
Only draw back to this is with MilkShape: It can't handle large files. It crashes if my model is too complex.
What I do is export in parts (if the model is too complex).

For Cheap?! I suggest 2 programs. Milkshape 3D and gmax. Milkshape is cheap and gmax if free. Milkshape will import and export .obj files and QIII files. gmax will import and export QIII files. gmax has almost all the modeling capablilities of Max 4.0. gmax kicks butt for the money - it is the best modeler out there (IMHO). I think it is better than studio max in that I don't load a bunch of plugins that tie up system resources (when all I want to do is make models).

Have you tryed using the "Window - Graph" to check out what is happening. If you have been using Poser for 6 weeks and you are attempting animation, my hat is off to you. It takes much time (months) to become skilled at 3d software that is any good (like Poser). It sounds to me, between your keyframes, you'll find in the graph that things need to be adjusted. Be patient.

Thanks for the great work! You da man!
