I would normally use the CTRL + ALT + Mouse buttons to change the values or move the timeline (with the middle button), however, when working on long scenes, it can be a bit of a pain to a frame as start or end.
So this little scripts will do the job. Here's a brief description so you know what each script does:
- UpdateStartZero: It will reset your timeline start value to Zero.
- UpdateStartTime: It will update the start value of your timeline to the current position of the slider. So, let's say your timeline goes from 0f to 500f and you want it to start from 333f. Just place the timeline slider to frame 333 and run the script.
- UpdateEndTime: Same as StartTime but for the end value.
If you want more control, you can also try the timeline script that is part of the JJTools package. Actually, I recommend to install the package regardless, it has some REALLY useful tools, like the Clever Move and Rotate.
InstallationAs with most of 3ds max scripts, just drag-n-drop the files into the viewport. I would recommend you put them in one of your Quad menus for easy access.
Cheers and have fun!
