I want to disable all the time sensor in a wrl file. I'm using vc++6 and cortona sdk 4.1.
You can't disable time sensors completely. But it is possible to stop (as well as slow down or speed up) engine time by implementing IExternalClock and set it to ExternalClock property of VRMLEngine. Note that this also affects behavior of other time dependent nodes, such as AudioClip and MovieTexture.
For more info, please see TimeTamer sample in Cortona SDK.
