Re: [osg-users] FBX Plugin: animation speed not as expected...
I'm sending a simplified version of humanoid.fbx. I could remove animations for all the bones but I kept just two: LeftArmRoll and LeftForeArm (I'm sending the file just to Michael because it is quite huge). I could just delete animation keys but not the bones themselves because without them the model would be messed up also in 3dsMax. One last note, when you open the model (also the original one) in 3dsMax or QuickTime everything works fine, but in 3dsMax you get the following warnings: *1) The following parent and/or ancestor node(s) is/are not part of the BindPose definition.* *-Humanoid:LeftHips_Dummy* *-Humanoid:LeftArm_Dummy* *-Humanoid:LeftShoulder_Dummy* *-Humanoid:Spine_Dummy* *-Humanoid:RightShoulder_Dummy* *-Humanoid:RightHips_Dummy* *-Humanoid:RightArm_Dummy* * * *2) The following object(s) use a rotation limit mode that is not supported by * *3ds Max (UseLimitsForRotationSpaceOnly). The rotation limits for the following * *node(s) will be ignored : * * -Humanoid:Spine_Dummy* * -Humanoid:LeftShoulder_Dummy* * -Humanoid:LeftArm_Dummy* * -Humanoid:RightShoulder_Dummy* * -Humanoid:RightArm_Dummy* * -Humanoid:LeftHips_Dummy* * -Humanoid:RightHips_Dummy* * * *3) The Initial position (or Initial Pose) of the skinned objects is missing. The plug-in will create a pose automatically but running the 'Assume Skin Pose' command may create unexpected results.* I guess that they can help you to better understand where the problem could be.

Re: [osg-users] FBX Plugin: animation speed not as expected...
Hi everybody, I'm still testing the FBX plugin but I'm still experiencing problems with animations. The humanoid.fbx test model that comes with the FBX SDK 2011.3 is displayed incorrectly by osgviewer and by osganimationviewer too (OSG 2.9.10). In order to try to understand where the problem is, I tried to simplify the animation (I removed everything but the left arm animation) but, since I'm not confortable with osgAnimation yet, I still cannot figure out the cause of this issue. The only thing I can think of, is that the model seems to miss an 'initial pose' (at least this is the warning that I get if I try to import the model in 3dsMax) but anyway 3dsMax, Motion Builder and QuickTime display it correctly. 3dsMax warns me that it will try to 'guess' the initial pose and actually it manage to set the correct one. Could the problem be related to a missing 'initial pose'? Maybe if such an 'initial pose' is missing then the model's starting position is messed up and so, when we play the animation, everything is messed up too. Any ideas? One more thing I've found out is that if I comment the following line: vi.push_back(osgAnimation::VertexIndexWeight(gi.second, weight)); in fbxRMesh.cpp then the humanoid mesh is displayed correctly (of course without animations) and the mesh rests in the 'arms spread' pose. Maybe there is somthing happening when setting the initial pose weights? Still guessing... Cheers.

Re: [osg-users] FBX Plugin: animation speed not as expected...
Hi Alessandro and Michael, I have similar timing-related playback errors on a multi-take FBX exported from MotionBuilder. Playback in: OSG 2.9.8 OSG FBX plugin built with: FBX Sdk 2011.2: fbxsdk_md2005.lib / fbxsdk_md2005d.lib FBX exported from: MotionBuilder 2011 QuickTime can move between all twenty(ish) animation takes and play them with proper timing. The only oddity is that after each animation plays, there is a variable length dead space on the playback timeline in which the model does not move. For example, the first 40% of playback is animated normally, then it stays in a static pose for the remaining 60% of the timeline. Playback is different using the osgViewer modified for FBX playbacks and changing takes/animations when a key is pressed. Calling playAnimation() moves the character to the correct initial pose but he does not move. In the debugger, the animation durations appear correct (e.g., 12 seconds) but for most takes the model is motionless the whole time. For a few takes, after a long pause the model eventually runs part of the animation at very high-speed, in the way that Alessandro's 3-bouncing-balls model played at high speed. Then even these return to a static pose for the remainder of their play time. My best guess is the timing is thrown off and this is somehow compounded across takes. The plugin has FPS hard-coded to 25 fps so we tried exporting at both 25 fps and 30 fps with only slightly varying results. I can email a sample file to demonstrate this (~15 MB).
