adding objects

Engines, Libraries and Tools Java 3D
#1

Every time if I try to add a object to the objRoot (BranchGroup) after making live, I get this exception:
javax.media.j3d.RestrictedAccessException: Group: only a BranchGroup node may be added

is this right?

if yes, is it impossible to add TransformGroups without the use of BranchGroups (after making live)?

#2

Yes, that’s true. Unfortunately.

I realled would be interested in the reason why, but for now, always encapsulate everything beneath a BranchGroup.

#3

I need it just for tests at runtime
