spinning a sphere 360 in 210 frames? spins backwards after 180

Mistara

goin nutz all day, >.<

i set the keyframe for the sphere with rotation 180, looking good so far.

when going the last frame i try entering 359, but it turns into negative 1 and the sphere spins backwards.  >.<

trying to make a very basic seamless gif loop.  without moving the camera. 

don't know what to do?  
 

thanks!

Try using the spin modifier

Mistara

well, but this is a learning exercise to rotate an object in sequencer

next trick is to get it to spin along a motion path 

Mistara

should i put in support ticket?  

WendyLuvsCatz

I can get it to work keyframing but is tricky

spin modifier is just so much easier

Set your object's "Rotation Controller" to "Angles", and you will be able to use rotation angles higher than 180 degrees. (see image)

Mistara

wwoww thank you!!!!

Glad to help.

is there a way to morph a normal round orbit into elliptical orbit 
https://en.wikipedia.org/wiki/Elliptic_orbit
was thinking like an electon orbiting nucleus animation

ironically, i failed geometry twice in high school

 thinking cap on.  Maybe find some way to combine (1) a central vertex sphere, and (2) a second sphere that is soft body attached to the first sphere at a tangent {but have the soft body settings very rigid so it keeps it shape}, and (3) spin the central sphere, and (4) make the spinning central sphere invisible (uncheck visibility or use an alpha shader).  OK, I think so far, the second sphere will appear to be rotating in a circular orbit.  How to make the orbit shape expand and contract in time for an ellipse?  Maybe (5) for the first sphere go to the modifiers tab and choose formula.  Make the axis upon which the softbody attach has been placed augmented by the parameter P1.  Then (6) make P1 a function of time synchronized to the time it takes the central sphere to complete a rotation. 

 Sort of depends upon how the softbody interacts with distortions caused by a modifier on another object.  But it might work.

look at the planets animation - you got with Carrara

he was the last time I looked.

mebbe that graphie thingie?  

 

cant stay awake anymore tnite.

Simple - Give the sphere rotation, set motion to motion path.  Draw eliptical orbit, let it run then change motion back to keyframes.  Make animation group, make NLA, looping:)

Mistara

the angles think did the trick for the rotation, plugged in 720 for an extra spin.

don't know what i did to make the infinite plane shader change.  looking through the triangles in sequencer

haz to be a more logical way to elliptic orbit

I just tried a simple set up similar to yours. I used a cube and a sphere, made the cube a child of the sphere, and moved the cube some distance from the sphere. I created a circular orbit for the cube by spinning the sphere 360 degrees over 4 seconds. Then, to make it elliptical, at 1 second and at 3 seconds I moved the cube closer to the sphere. I also had to move the cube back "out" at 2 seconds to create an elliptical path. I had to smooth out the keyframes in the Graph Editor because the cube made a weird "bounce" at the 1 second and 3 second keyframes. Not sure if this is a super precise method...

the graphie thing is pretty mysterious

Instead of animating from 0 to 360, try animating from -180 to +180
