Question:Conveyor can run but the source always go down which parameter set wrong?
The colliders of the MU are not defined as they should. You can compare with the MUs in the Demo scene.
You need to have at least one box collider on an MU which is on the layer g4a_MU (see my sceenshot). This layer is working for transport collissions as well as sensor collissions.
Please also check:
The example MU in the demo scene is even more complicated. It has two colliders - one for the transport (like realistic rolling on the bottom - on the layer g4a_TransportMU) and one for the sensor on the layer g4a_SensorMU.
Hard to say - please compare the source settings with the demo model or send us your model and we will check what is wrong.
now can move jog forward, but always under the conveyor. the MU intial is at conveyor top level. but after clicl play button will go down and move forward.
