 F-Curve [/Keyframe] pause on Align to Spline - How to fix? on Sep 9, 2015 at 1:19:46 am

Hi community,
I have a camera circling an object on a circular spline. I have an F-Curve on the Align to spline- Position. But when it transitions from 100 to 0(to repeat) there is a pause. A dead frame. I can't find a way to transition smoothly. If this was a video loop, I'd just remove the last frame(as I have done before). But it isn't, so I can't.

Thanks.

I assume your F-Curve is linear, you can't go from 0 to 100 since 0 and 100 are the same thing - your top value has to be less (the math equivalent of removing the frame in video) you can do the math - last frame value = 100 - 100/number of frames or you can set a keyframe one frame before your current end keyframe (in the 0 -100 sequence) delete the last frame and move the "one before to the last place

Yes, Linear, but I tried all others. I don't know if it matters, but it's 100 to 0, not 0 to 100. I understand they are the same position.

I'm usualy quite good at this, I had already tried dividing the number of frames(149) by 100, then - from 100 to get the last point level(99.328%). But thats where I got stuck.

I don't understand "delete the last frame and move the "one before to the last place".

EDIT: The first time I divided frames, because the velocity doesnt show up, and it wasn't a smooth annimation, I thought it didn't work. However, I have now realised that the 'dividing by 100' method wouldn't work, as I changed the velocity in the 149 frames. I guess that's what you meant when you asked if it was linear? I thought you meant the 149th frame point type. I now added the keyframe, and removed the last frame and everything is as smooth as silk.

thanks for help anyway...

RENDER TIME!!
