The conditions for pasting time into a track are:
If the above conditions are not met, the Paste Time function has no effect.
Time editing is available only in Dope Sheet mode; it is not available in the Function Curve Editor.
In Edit Time mode, you can copy and paste controller tracks that have no animation keys. When a track has no key, its value at frame 0 is used. You must select a block of time before cutting or pasting; otherwise the time is ignored.
The values of all the pasted keys are adjusted so that the first pasted key has a value equal to the value at the time of the insertion point. For example, the value of the controller at frame 50 is 10. The clipboard holds three keys spanning 50 frames with values 20, 30, and 40. When you paste the three keys at frame 50, the first key has a value of 20, but the insertion point has a value of 10. 3ds Max subtracts 10 from the pasted key to maintain the value at the insertion point. 3ds Max then subtracts 10 from the remaining pasted keys, resulting in three pasted keys valued at 10, 20, and 30. In addition, any keys after the insertion range are also adjusted by the net change over the range being pasted. The net change is the value of the last key pasted minus the value of the first key pasted. In this case 40-20=20. Every key after the insertion point is increased by 20.
To paste time into tracks:
3ds Max opens the Paste Track dialog.
Options on the Paste Track dialog are as follows:
