Re: [osg-users] Blender osgAnimation Issue
Cedric, Thanks for taking the time to look into this. I did have a revelation a few days ago that lead me to the same conclusion. Basically I had to go back and assign vertices to the named vgroups. not a big deal once I figured it out I was just going crazy thinking I was doing something completely wrong. I figured the exporter should recognize this but it works perfectly if I do the following: -select a vgroup -select the vertices I want in the group -click the assign button that seemed to fix my issues. Again thanks Cedric for all your help and hard work! -Russ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Blender osgAnimation Issue
Well I've been unable to figure this out on my own. It appears to me that I am following the same setup as in the robot.osg packaged with the blender exporter but when I run osganimationviewer I get no bones found errors. What method should be used to parent the Armature to the Mesh? I know there are a few ways to do it and maybe I'm simply doing it incorrectly.

Re: [osg-users] Blender osgAnimation Issue
Haha, as soon as I posted this I knew that was going to be the response. I know there are several ways to do armatures in blender, my basic test process has been this: 1) create a long box 2) subdivide a bunch of times 3) create a vertex group 4) create the armature (2 bones) 5) add an armature modifier to the box 6) parent the armature to the box (CTRL-P) This apparently doesn't work, is there a different process that the exporter requires? I'll submit a file if that is needed. Thanks for the continued help guys!

Re: [osg-users] New SVN Broke osgAnimation?
Ok I have some information that may help you. I can run
osganimationviewer against the robot.osg file provided with the
Blender exporter, however when I download the robot.blend and export
it the resulting file begins with
osgAnimation::AnimationManager {
instead of
Group {
when I export one of my .blend files I get a file starting with Group
{ but the viewer seg faults.
Hope this helps a little!

only for the models provided by the osgAnimation project. The models I've
created in blender don't export the osgAnimation { } portions that are in
the Jancens.osg and others. It appears the model format has changed and the
blender exporter hasn't caught up (i could be wrong about this). At this
point I'm going through the AnimtkViewer code to try and hash this out. I
haven't got my code to play animations through the AnimationMap class yet.
