  1. In this file I added some more parts lifter_0003.c4d
  2. You could use a message box import c4d from c4d import gui def main(): gui.MessageDialog('only 10 days left') as in 'Hello World' ...
  3. I don't get the relevance of the number of teeth. To turn any object 360 deg in 60 frames is 6 deg per frame so just multiply frame by the radian equivalant of 6 deg in XPresso. To make a loop, render frames 0-59 inclusive. 2cogs.c4d at that speed, there will be strobe effects, so stuff will appear to go backwards etc - Hollywood wagon wheel effect... I'm a big fan of Looney Gears
  4. A bit of scissor trig for you lifter_0001.c4d
  5. Just uploaded a breakdown video to Vimeo here.
  6. I don't really understand constraints enough to make a tutorial about how to use them. In the video above I added an aim target for the input shaft and an aim constraint pointing the input shaft at it, then animated the input and output aim targets on splines, with a camera moving on a tilted circle. Here's the scene - joint 12.c4d re your earlier question about the guy in the video using more constraints - maybe he used a parent constraint, but I just physically parented it in the OM. edit - also the shaft speed is keyframed smoothly between +/-
  7. @cinomadic - I had a go at making my own
  8. When it comes to things rotating at varying speeds eg helicopter blades, gear rigs etc, most people do it wrong. For fixed speed, just multiplying seconds for rot H or whatever is fine, but if you try and spin the chopper rotor down to stop by adjusting the multiply factor, it tends to go backwards - seconds * 0 = 0 so the object goes backwards to its starting position. if you generate rotation by addition eg rotation = rotation at last frame + <small value> adjusting the <small value> varies the speed. In my python there's the shorthand rotation += speed which means add the RHS to the LHS to get a new LHS value. You can do a similar thing with align to spline speed.
  9. and you got a free python speed control
  10. TBH I just tinkered until it worked.
  11. This might be it, or it might not be... joint.c4d constraints confuse me somewhat
  12. Ha Ha my old videos have come back to haunt me. I made these vids years ago, and later removed them from Vimeo with the intention of making better ones - but never got round to it. So they are on YouTube without my permission (or knowledge). So fire away - what's the question ? I had a few methods for camera sync - in this video using XPresso I take the average position of the cars and use a memory node to place the camera about 1 second behind. The camera targets the average center. victim of piracy - fame at last
  13. You're not allowing for the time spent during tutorials, at SIGGRAPH etc explaining the 555 malarkey. Probably breaks even . The bit in the video linked above where he simulates the air inside Tubeman by sending the wind object along the tracer generated spline is typical CS creative thinking.
