Ok Guys, there was a bug which prevent script to relay on the correct AnimationGroup to add the node. I solved it and publish a PR related to it. Be aware that there might be a delay for the PR to be merge.  
Assuming a Group named “Animation” exist, the following script

> manager = dotNetObject “Max2Babylon.MaxScriptManager”  
> g = manager.GetAnimationGroupByName “Animation”  
> id = $.handle  
> manager.AddNodeInAnimationGroup g id

works now.

Happy christmas.

Hiello. Thank you for what you explained. I can create a group and add nodes, but when i try to change the FrameStart and the FrameEnd of the animation group in maxscript, the values are not correctly stored. What’s wrong ? How to do ?  
Moreover, do you know where i can find all the properties/attributes of the dotNetObject “Max2Babylon.MaxScriptManager” ? (as “CreateAnimationGroup”, “RenameAnimationGroup”, etc.)  
Thank you for your help.

maxScriptManager = dotNetObject “Max2Babylon.MaxScriptManager”  
aniGroup=maxScriptManager.CreateAnimationGroup()  
maxScriptManager.RenameAnimationGroup aniGroup “TestAni”  
testAni=maxScriptManager.GetAnimationGroupByName “TestAni”

testAni.framestart = 10 → this property exists but the value is not crorrectly stored and exported
