  1. Hi I have an animated mesh and would like to attach a null to one of the points on the mesh. How can I do this? Thanks
  2. Hi all - two questions 1. If I have two nulls, both with animated position, is there a tool in cinema to create a simple spline between the two nulls, which will animate according to the position, changing length accordingly? 2. If I have a circular spline how can I randomly distribute points on the spline (i.e rather than uniform subdivision)? Thanks
  3. Hi Cerbera - long time ! houdini node trees don't just go up and down - or in fact left to right - a model can exist in several parallel (universes) at the same time. If you are interested check out Peter Claes's series on building a bridge
  4. Hi @Cerbera do you use spline patch in your modelling workflow? I’ve been lost learning Houdini where coons mesh is very common.
  5. Thanks @Cerbera yes that’s what I thought. Surely this is something MAXON could/should think about adding to the pipeline. There’s been many moments in the last few months where it would have been useful
  6. Hi - do we have any tools beyond motion tracker to bring video footage into the viewport in c4d? im trying to rebuild some moving objects in a video for the sake of dynamics interactions and find motion tracker does not work in all situations any workflow tips would be much appreciated (ideally without leaving c4d)
  7. unfortunately not - forester is procedural and so cannot interact dynamically with other geometry assets. If you were working the other way around you may be able to get this to work by exporting the tree/flora as alembic and then potentially c4d objects could interact with it. But in this case the tree would drive any simulations. And the alembics that forester produces are so heavy that it would take a very powerful CPU to make it work.
  8. Only that if you set / apply a material and define UV mapping before you simulate it should already be correct after the simulation. TBH I don't know if that also applies in MD but it does in C4D, say if you were using its own cloth system. CBR Marvellous Designer attributes UV's to all MD generated geometry before any simulation takes place. The UV attribute doesn't automatically transfer to your export geometry (.obj/fbx/abc) and so you need to manually select it in the export options dialogue in MD. Don't try and (re) project UV's in c4
  9. Hi All can anyone help me figure out a mathematical problem regarding frames per second. I am preparing an animation sequence to go onto a render farm. I have animated a character and camera - which all looks good - except that when I did a hardware render I decided the clip should be half the speed. Now I can't quite work out the best workflow for this. Normally I just leave scene FPS at at 25 and change the render FPS to 50. But the render farm I am working with cannot accept variation between these two and so I need to bake in the slow motion. With
  10. Is it possible to link a null to the moving coordinates of a specific point on an animated mesh? in fact I would like to link several hundred to different points on a moving mesh, but guidance for one would be fantastic. thanks
  11. Don't mix c4d procedurals inside a vray shader as it will cause vray to be unstable and is often the cause of crashes. It also can cause unpredictable results with DR. If you use a power shader you cannot use one of the c4d shaders inside it. Adv bitmap gives enough options to be more powerful than filter, for layers you have Tex Layer Max. There's little reason to use fresnel filter as the inbuilt fresnel options are excellent in vray. The most common limitation with vray shaders is the noise - which are far less developed than native c4d. You can in this case texture a model the
  12. Hi All I have an alembic animation that I have built in houdini - simple question - I would like to include several (render) instances of the same animation within a scene but each offset to start at different frames. I see that its not possible to manually modify instances - but I was wondering does instancing actually matter with alembic? since it is always referring to an external file? it's a heavy file (2GB per frame) and for the sake of rendering I am trying to keep my geometry loading times to a minimum. Is there a way around this?
  13. @Havealot perhaps you could also help me. Using your R20 file - for a separate situation - how would I go about keeping the exposure/time constant (say 50%) and then simply letting the noise animate?
  14. Hi all i have an animation sequence which includes a cloner object set to grid with 4,000 clones. The clones are static - camera moves through the clones like moving through a cloud. is it possible to randomly animate when each of these clones appears as on in render? so in frame 0 no clones appear and in frame 100 500 random clones appear and in frame 250 4,000 clones appear. By appear I mean off for render view and then on for render view next frame. once on clones remain on. im rendering in vray 3,61 and so ideally fo
  15. Hi I am trying to work out a way to animate a computer mouse cable. The mouse will move on a surface around x and z axis and I had drawn out a sweep spline for the cable, but am looking for best way to make the cable move in a realistic manner i.e bend a lot close to the mouse and not so much further away. I guess one way of doing it is with an IK chain. Is there a way with splines to fix some points on the spline so that the curve moves dynamically? thanks
  16. it looks like you could benefit from spending more time learning the vray physical workflow. there are several ways to learn, but the only real up to date method is to follow Stefan Laub's Vray for c4d Masterclass. It's worth every penny
  17. this is not true. Although the current implementation of projection mapping in vray for c4d is not as easy to work with as the native c4d material system. It is possible to do what you want with the Vray UV manager tag. it is by no means an ideal solution and can be a little difficult to use. But ultimately this is the most advanced way of managing multiple forms of mapping onto the same mesh
  18. Thanks @zeden I will still be going beyond January, I just need to close this particular scene by then. So if you have any time please get in touch. @Freemorpheme many thanks, I will send you a message
  19. you don't necessarily need a blend material. Depending on your setup you can use the two diffuse layers in an Advanced material - use the lower layer for the wall - top layer for decal with alpha placed into transparency slot in diffuse. You can then copy this setup for the speculars if you need different specularity for each.
  20. Hello everyone, I would like to reach out to the c4d community to ask for help for an ambitious film project that I am working on. I am an artist and academic based in London and have spent 2 years working on a 60 minute experimental film called "Quasi-Monte Carlo". The project is 3/4 completed, but I have realised that I have run out of time to complete the remaining modelling/texturing to a level that meets the work already completed. And so I am asking if anyone is interested in supporting the project by undertaking one of many small modelling tasks, which would normally take
  21. In the case last night the scene file was initially saved into a folder dedicated to the textured model. As in I placed the textures there initially and they did not exist anywhere else on my system. All of a sudden they are gone?
  22. Thanks @srek i see your point but I can't think of any other way this can be happening. I do a test render , all is fine. I save a backup with assets, close this file and reopen the original local file and the files have moved from my tex folder
  23. Hi i have come across a (bug?) several times recently and wondered if I am alone? intermittently when using save as with assets command, some of the texture files are moved to the new location rather than copied. for example last night I setup a render queue and found this morning that the render was incorrect as some tex files were missing. I save all files onto a backup drive, but had set the render to read the file on my desktop. eitherway, I have had this problem several times recently and it has been costly, any advice here?
