View Full Version : Need help with spline animation...

I have some questions about doing a Spline Animation. I've posted my project here:

<http://www.hsmm.com/3danim/test/splineanimation>/splineanimation.c4d>

At the very end of the animation, my box is moving too fast and I don't know how to slow it down. I keyframed the Position, but it is reaching the 100% position before the keyframe in which I made it 100%. Can someone look at this file and give me some pointers? I need the box to move at a smooth and steady rate throughout the animation.

Wild guess, but what if you change the spline interpolation to 'uniform' and set a nice value for number of interpolated points.... does that help?

Oops! I just realized that there was an error in my path. This one should work:

However, I have figured out part of the problem. It was in the f curves. I have noticed in other instances, however, that as the box rounds a corner it seems to speed off of that corner. Could that be adjusted using the ease in/out?

I believe I already have them set at "uniform" and my values are currently at the default of 8. I wasn't really sure what impact a higher value would have on either the speed of the box along the conveyor belt or the rendering time. Do you know?

Treebird,

Just looked at your animation. Your keyframing is the problem. You need to place exact keyframes for the begin and end of both when you keyframe the transition between spline path and also position on each spline path. If you look at your keyframe you can see that you are off. You need to re-keyrame those areas. For the rest of your animation, it's the same thing but there are also areas of overshoot. You need to change the interpolation of the KEYFRAME not the spline for these situation. I did not check these since your animation is so long, but changing them to Custom in most cases should fix this. I did however fix just the helix area at the end if your need it. I can send it to you if you need it. The compressed file is about 4MB.

Hope this helps
