  1. The fall offs are making the density and size of the cracks in the middle.
  2. Hi all. I'm using voronoi fracture for the first time trying to simulate a shattering window and getting some unwanted effects. One issue I'm having is that the just as the fracture happens the pieces that are pushed outwards snap back to their original position 1 or 2 frames after they initially move. I have attached a scene file with cached dynamics. If you scrub through frame by frame you will see what I mean. The other issue is that after the surface smashes the pieces fall unnaturally quickly. Any help would be appreciated. shatter test 1.0.c4d.zip
  3. Hey. Thanks for looking into that. It seems like thats the default setting, maybe only an issue if you're working at small scale.
  4. Hi all. I was just doing a simulation with some clones and found that some of them are just freezing in one position. I can't really figure out why thats happening. I attached a scene file if anyone wants to have a look. Thanks in advance. freezing_clones.c4d
  5. Hi guys. I'm trying get a simulation using low poly dynamic objects and then replace those objects with high poly versions. I can do this with a cloner and some xpresso but I want to recreate the same thing using xparticles. I've got part of the way there by using one emitter to generate the low poly objects with a c4d dynamics tag applied to their generator, then using a 2nd emitter pointed at that generator with 'stick particles to source object' checked so the particles follow the motion of the 1st emitters dynamic objects. This works for the position but I'm not able to pick up the rotation of the dynamic objects. Is it possible to do that? Sorry for the complicated description and thanks in advance for any help.
  6. Simple xpresso question

    Igor, yeah it's good to have the option to join the subscription based forum for sure. Jed, thats spot on, thanks for the help. I was almost there with it but just wasn't hooking up the indexes as you did there. Cheers
  7. Simple xpresso question

    Hi Igor. Yes I know of the subscription and might be interested at some point but for this it seems a bit over kill. It's a very simple thing I'm trying to do (if it's actually possible). Hope we're not moving over to a help on subscription basis here.
  8. Hi all. I have a quick xpresso rig I wanted to make but I'm running into unexpected problems. I have a group of splines and a group of matrix objects set to object. I want to plug all the splines into all the object slots on the matrix objects so I don't have to go and do it manually (theres a lot). I thought I could do that with a hierarchy node but can't seem to get it working. Can anyone point me in the right direction?
  9. C4D and GPUs

    An update on what I found out directly from MAXON on this subject... if anyone's interested. Dynamic calculations are entirely CPU based and single thread at that, which means having 12 cores isn't going to be any better than 1 for this purpose. GPU helps in displaying the viewport but not in calculations. Seems like something like an i7 is sufficient if you're running a GPU renderer.
  10. C4D and GPUs

    Yeah I'd definitely wait until they update the cpu in the MacBook Pro before buying one and the new Mac Pro is a bit of a gamble. Could be rubbish for 3D and could take 18 months to come out, no one knows. Cheers for the advice on using activity monitor, I'll give it a try and see what it comes up with.
  11. C4D and GPUs

    Is there anywhere I can find in depth info in exactly where cpu and gpu come in to play? Or maybe you can explain a little further what makes cpu so important? I'm currently using a maxed out Mac Pro with 12 cores but thinking I might be able to swap over to a new MacBook Pro with some external gpus.
  12. C4D and GPUs

    Hi all. I'm thinking or switching to a more gpu focused setup at some point in future now some 3rd party renderers going in that direction. One thing I was concerned about is whether having less powerful cpu would have an effect on things like soft body simulations and caching those simulations. I know some 3rd party stuff like realflow and tfd can use a gpu for their simulations but what about native c4d simulations? Thanks for the help.
  13. Yeah, seems to work fine, just takes a while
  14. Cool, well at least I know I'm not wasting my time then. Cheers
  15. Hi all. I have a lot of objects with hair applied. I need to cache them all but the cache only calculates the individual hair object, not all hair objects in the scene. If I select all the hair objects and press cache, it runs through the animation once per obejct so I have to sit there whilst the animation runs through 50 times consecutively. Is there a better way to do this?
