- On the Render dialog
Render Elements panel
Render Elements rollout, click Add. In the Render Elements dialog that appears, highlight Velocity, and then click OK.
- Highlight the Velocity element in the Element Rendering list.
- On the Velocity Element Parameters rollout, turn on Update, then render several test frames. Choose frames where object velocity appears to be the greatest.
- After each test frame, make a note of the Maximum Velocity value. If you need to do so, enter the largest of these values as the Maximum Velocity to use.
Having a specific Maximum Velocity value will give you more accurate velocity data.
- Turn off Update.
Now the Maximum Velocity will remain constant.
- Render the animation.
