I need some help I have been playing with this for over 4 hours, something I thought would be very simple is giving me all kinds of grief. I have a simple Sphere. I have a planet texture on it, which is a JPG image texture, it is applied Shperical so it wraps just fine. But now I am trying to animate so it looks like the planet is rotating and very easy it is rotating on its Y Axis. I thought this would be rather easy. But it is giving me nothing but grief. In the entire time 5 seconds I want the planet texture to rotate 359 degrees. But when I go to my final Key Frame I enter in the Y Rotation to be 359, I click ok yet Bryce Changes it then to -1 and of course my texture only rotates -1 degree in the 5 seconds which is not what I wanted. So then I went in to det up multiple keyframe and I figures I would rotate it a little at each key frame, Which works great until the final keyframe, which it changes again to -1 so my planet after spining in a regular direction and a nice normal speed the last second it spins backward at a really rapid rate to -1. I have tried rotating the Sphere which I don;t know if it is rotating or not but the texture doesn't seem to rotate with the sphere, which is why I went after the texture. Anyway how do I do this

I've not tried animating a planet like that. I always set the first key frame, go to the last and use the rotate icon to spin the planet around the Y axis in the direction I want. Doing this also seems to let you do multiple rotations. Not sure why your multiple keyframing isn't working. Sorry I can't help more.

I've rotated planets in animation and rotating the sphere itself worked just fine. Maybe try a short five or six frame animation, key frames at start and finish, and rotate 30 degrees per frame. The other thing I usually do is manually rotate the object rather than entering values.

Have you tried just rotating the sphere itself ???

Yes I think I got a solution, I tried the sphere, and tried the Sphere, and tried the sphere. However I noticed, I had no trouble with any objects I made in Rhino, so I made a simple Sphere in Rhino and exported it, imported it into bryce and the rotation now works just fine I tried another Bryce Sphere and got same odd results, but the Imported Rhino Sphere works, I dunno must just be an odd quirk. Thanks guys

One thing comes to mind if you rotated the sphere yet the texture didn't move, check the mapping and make sure it isn't set to world.

Yeah Bryce definitely has some animation quirks. I run into probs every time I make an animation. Even simple airplane propellors seem to be a real chore at times.

turn auto keyframing off in the animation menu in the lower right of the screen. As aldaron said, if the texture is set to world space, it will not move with the object. Use object space or parametric mapping for good results.

You DID mention that it was set to Spherical, I don't know why the others missed that. Bryce has a few quirks, but relatively few bugs. I once animated the Gravity Drive from that movie, "Event Horizon", not in nearly as much detail mind you, but just to see if we could get the math correct, it took HOURS!

Hmmm I did miss that. Sorry :)

I have animated many planets in many different apps, I take the same approach in all apps ( including Bryce ). Use 5 keyframes,.... keyframe 1 starts the animation with the rotation at 0, keyframe 2 rotation = 90, keyframe 3 rotation = 180, keyframe 4 rotation = 270, keyframe 5 rotation = 360. Never tried rotating the texture only in Bryce, but it worked fine rotating a primitive sphere.
