Hi Tapan_Boro  I have attached a path editor made by an other forum member Shadmar.

I have made a change to it that uses a camera to follows the node cursor.

You can use a rigid body as terrain instead if the default terrain, just change the Rigid Body to included to your own. Then remove the comment '//' marks on the third line of the scrip.

To use left click the terrain for your node position, then press 'Q' key to save that node. There is a file created in 3DRAD root folder called 'mypath.txt'. When finished you must rename it because it you don't it will be over written when next time you use patheditor.

have fun
