Subject: Animation help needed: Time splines?

http://www.vuerealism.com/renderchallenge02/oaa_and_taa.wmv I'm having a problem smoothing out my animation. Even though I have the camera set to smoothed velosity and ease in/ease out, I get this jump around 10 seconds... Is this something I'd smooth out via time spline?

Hi Ryan Nice scene - good work! I'm 99% certain the problems is due to you adding Camera Keyframes (intentionally or not) at these points and Vue recalculates but still has this changing of camera direction. This is what you need to do: - Use a camera Start and End keyframe only (none in between). - Create and invisible/non rendered sphere in front of your building. - Make sure your camera points to this sphere. - Adjust your SPHERE position rather than the camera to adjust any camara angle direction adjustments throughout the animation i.e. keyframe your sphere marker as many times as you like - the camera will track it smoothly. Also you won't need to use Smoothed animation but you can use Ease In/Out so the camera speeds up then slows down (if that's what you want). Payment in used banknotes in the usual offshore bank account as please Ryan >9o) Kind regards

Never thought of it that way. It's genius, quite simply. That was how I was doing it. But what happens if the speed of the camera is not supposed to be consistent? Say you want to slow down at parts and then speed up at others because I dont necessarily want a constant speed...how is this done smoothly? I wish there was some good Vue animation training available.

Hi Ryan In that case - you can add Camera Keyframes, but as soon as you select Smoothed velocity - your camera path may 'buckle' to compensate for the fact that your position Keyframes may not be equidistant relative to time (so you need to move these markers around both in the top-down and animation timeline view. It can be a tricky juggling act! If you open the Windy Hill tutorial however - you can also learn quite a lot about the function editor and changing only certain keyframe characters. I totally agree - if Philippe Bouyer were to offer his camera secrets for sale as a tutorial - we would get caught in the stampede to learn the Maestro's skills! >8o) Kind regards

Well I'll do research and it'll be on VueRealism.Com. This lack of training/documentation is frustrating!

The only way I've been able to animate a camera in Vue is by using the synchronization plugins with 3dsmax. Vue animation by itself is almost impossible. Once you get an animation down and start tweaking it, it will almost invariably get corrupt by vue at some point...duplicate key frames, keys missing, all sorts of nonsense. If you have a package that Vue synchs with, save yourself the headache and use that.
