Milkshape Exporter Issue. Skeleton or bones screwed.

[old_man_auz]

Hey,

Sorry if there has been a something written about this that I havent found. I have an animated mesh. It plays its animations fine in milkshape. The following screenshot is of my models idle animation.


I can export the the mesh from milkshape to the Ogre mesh format fine. Once I load the mesh into Ogre. It moslty looks right, except that some of the mesh animates incorrectly. Its like some of the bone positions are in an incorrect positions. Here is a screen shot of the same animation above, showing the problem. All the animations exported have the same problem, though some seem worse than others.


Is this my fault or the meshes fault.. What can I do to fix this.

Thanks in advance for any replys.

Please post the original Milkshape model.

is there somewhere I can host the file or can I email it too you ?

[sinbad]

You can mail it to me since I wrote the exporter.

[old_man_auz]

I emailed you the file.

Thanks for your help.

Thanks - I won't get time to look at this until tomorrow night though.

Thats fine.. Ive spent a week or two mucking around with it, trying different things, which doesnt mean much becuase my knowledge isnt that great. Im in no rush.

Hmm, well it's almost impossible to see anything in ms3d since it's just a jumble of bones all on the same spot. Do you have a version which is easier to see the structure?

[old_man_auz]

The model is very small.. do you need to zoom in and change the bone size?
I have the bone size set in milkshape to 0.02 ( Under file, preferences, misc, joint size )

I use a scale of 1 unit is equal to 1 metre.

If thats not the problem then let me know.. I can get you a bigger version if you like. I just opened the file I sent you on my computer and it works fine, so I think it works ok.

*update*
I emailed you a bigger version.

Fixed it now, the bigger version helped - I use Milkshape so little now I didn't remember how to change the bone size. The fix was simple but subtle:

thanks alot mate.. really appreciate it.

Ill try to apply the patch manually, but Im ignorant, so I mightn't be able to do it. If I can't have you updated the milkshape exporter on the website ?

[old_man_auz]

mate.. just tried it and its workin like a champion..

thanks again..
