Activity Forums Maxon Cinema 4D random effector not changing over time

  • random effector not changing over time

    Posted by Hilary Tsai on April 19, 2021 at 6:57 pm

    My random effector does not seem to be working properly in any situation. I tried Motext with a fracture and random, for example, and the random appears to change the letters; but when I preview the scene, there is no change from frame to frame. I also rendered it out and saw no change, like the random was stuck on one frame the whole way. This also happened when I tried random with a cloner. This only started happening very recently. I’m using S22, but I tried it on previous C4D versions and the same thing happens. I wonder if something got deleted off my system that effects the random effector, but I doubt it. Does anyone know what the issue could be?

    Hi Hilary,

    Unless I’m misunderstanding your issue, in order to get animated randomness you need to select either Noise or Turbulence in the Random Mode setting, otherwise you just get one random value based on the seed. For the other modes you would need to animate the seed to have any change over time.

    Edit: I forgot to mention that you could also animate any of the actual parameters (x, y, z position, for example) or the effector strength, but if you’re looking for automated randomness use Noise or Turbulence.

    I cannot believe I forgot to change it to noise! I even knew that, but it’s been a while since using random and I just spaced out. Thanks, Jim!!!
