Attached Link: Help Spin My Wheels

Hi, This is a great site and I have learned a LOT from all of you, THANKS! I've got a problem that I just can't get over, I have to ask for help, sorry. How can I make wheels appear to be spinning in a Bryce animation? I've tried selecting the wheels and using auto key, moving the time line to the end and then using the rotation control or even setting a numerical value in the attributes box. But I get stuck at the 360 degree mark, when I need the wheels to appear to be making many rotations during the time line. I tried moving part way along the time line, rotating, moving some more, rotating some more, but then the wheels either stop completely, or start rotating backwards! Can anyone help me figure this out? I remember reading somewhere that there is a trick to it, but, of course, I can't remember where I read about it! Bryce is a fantastic program, I really enjoy it, and reading all the neat tricks and tips you all post. It's very inspiring! Thanks!

You could try setting the wheels textures to object space mapping, that way the texture will move as the wheel moves simuling a tire actual spinning

easy fix: Make your wheel rotate once, from 0 - 360 degrees, with one keyframe at the very beginning of the 'wheel motion' time and the other keyframe at the very end. Next, go into the Advanced Motion Lab. One of the shapes across the top of the motion curve editor is a sawtooth: this is what you're looking for. Select the sawtooth shape. You can play with the number of 'teeth' to increase or decrease the speed of the wheel. What this shape does is increase your wheel's rotation from 0 to 360, then in ONE frame sets it back to 0 again and starts it spinning. From the animation point of view, it looks like it's spinning continuously. NOTE: I think this actually creates a wheel spinning with a 'hiccup' in it. The reason is that you get one frame at 360 and the very next at 0 (which are the same thing). So you get two frames right next to each other, once for every revolution, where the wheel appears to stop momentarily. You can eliminate this by having the wheel settings go from 0-355 instead of 0-360, or 0-345 instead of 0-360... you'll have to play with the exact number to get it to look right, because it's dependent on the wheel speed and frame rate. Happy spinning.

ha, I lied! The sawtooth is one that I made and added to the list of presets. You can make one pretty easily, then add it to the list of presets by scrolling it to the gray square, and clicking on it. voila! (a sawtooth looks like this:)

Hold down option/alt and click to delete one of the presets if you don't like it. They're persistent from project to project. Happy spinning
