  1. I had a go at brownian-type motion a while ago, using force on dynamic objects - each object has a repel force. I found that with regular dynamics and collisions, things tend to slow down after a while, and upping bounce to fix this can make stuff go crazy. In this scene, to get bounce on the wall I cloned some objects along the wall, each having a repel field. There's XPresso random init velocity, so it's different every time. brownian.c4d might be some ideas for you
  2. I think this does it. I used clamp and iteration rod6.c4d
  3. I used to have a lot of fun with Nitro4D's SoundFx (triggers a sound on collision), but around R17 or R18 it seemed to no longer work in C4D. However, Nitro has upgraded most of his plugins to work in R20, including SoundFx . A quick test - if you click bake, it writes the sound to the timeline. https://nitro4d.com/product/soundfx/ well, it amuses me...
  4. Put your camera in a null and align the null to the spline. Then you can adjust the camera back to 'normal'. In the video, the plane is in a SDS and he is rotating the child.
  5. It's not a physical constraint - the XPresso clamp just limits a number to stay between a max and a min value.
  6. The GPU probably adjusts its fan speed according to temp - maybe 80C is the target. How is the CPU cooled - screw-on heat sink fan or water ? Regular coolers just dump the cpu heat in the box, so more fans should drop the cpu temp. Water takes the heat outside, so is less affected by another pair of fans.
  7. Function - Sort Materials, or R-click a mat ditto.

    Is it me, or has the Cafe log in changed ? I usually surf the forum not logged in and only log in to download a scene file or maybe make a comment. Recently, it goes straight to the log in page with no option for quick anonymous viewing. I checked 'who is online' and it shows anonymous + guest - here 214 guests, so I guess some non-members are reading the forum it's no big deal - I can set the Cafe cookie to not delete, I was just wondering if membership rules have changed.
  10. Glad you got it sorted. BTW - you're not a dunce. The topic of helicopter blades etc going backwards crops up here and on CG Society on a regular basis.
  11. The problem is generating movement - rotation or linear - using multiply, either time or frames. It's ok for constant speed, but think what happens if you dropped the multiply value down to zero to slow it down. Zero times anything equals zero, so the object goes backwards to where it was at frame 0. In the files above, the movement is generated by addition, and the amount added every frame is the 'speed'. If the amount added is reduced to zero, the object just stops - doesn't go backwards. I've got a Python XPresso node that I paste into scenes to control speeds eg gears. If you've never used Python, don't worry - it ain't scary def main(): global offset frame = doc.GetTime().GetFrame(doc.GetFps()) if frame == 0: offset = 0 else: offset += speed * 0.1 Basically it sets the offset to 0 at F0, then adds 10% of the speed slider every frame. If you change the slider user data range to -100% > 100%, it also goes backwards. ' += ' in the last line means evaluate the RHS and add it to LHS, so LHS has a new value.

  12. Here's some C4D Python for noobs - random lottery generator spins the numbers, then sorts + holds lottery.c4d I use this speed control a lot for my gear projects etc arrow.c4d a bit more complex - this wheel on a chessboard rebounds at the edges, keyboard ctrl + alt steers L-R wheel.c4d math for wheel available on request
