Constant Velocity Along a Curve - Matinee
I've been trying to figure something out for a while now and nobody seems to know the answer.
I'm trying to move a camera along a curved path in matinee. However, no matter what I try, the camera movement will change velocity (usually easing in and out at each control point) as it traverses the curve.
Is there any way to force the movement of the camera to have a constant velocity over the distance?
For instance, I would like the camera to move along an arc over 5 seconds... but at a constant velocity over those five seconds.
The only method that I've been able to get to (somewhat) work is to child the camera to a target point and then rotate the target point 90 degrees over four evenly spaced keyframes. This is not ideal as I would like to be able to do more than just circular movement. Also, once you detach the camera from the target point, the matinee uses the local position and the camera just stays still (I was hoping that I could create the curve and then use it elsewhere).
Sorry, you are right. Linear wouldnt work in this case. To get Normalize Velocity option > Split Translation and Rotation > right click on Movement Track and you'll see it. I set its start and end to the first and last frames of the animation and the trajectory appears messy in the level but the velocity sems to be constant now. Give it a try and let us know!
