  1. That lets me move the path, thank you so much! Do you know how I can change where the camera is pointed? Right now if I rotate the camera it rotates the whole path.
  2. I've just discovered the Autokeying feature, which is amazing! I've been putting flight paths through neurons from our lab and it used to take ages! Now it is quick for me to lay a path buuuuut I'm definitely doing something wrong because the camera is doing all sorts of off wobbles and changes in focus. Also I cannot seem to figure out how to edit the path after it's laid. So I delete the keys and start over, probably not the best way. Here is an example render I just made of some strange neurons from a fly's brain that shows the odd camera movement.

  3. Hi all, I'm working on an animation for our lab for iPhone and my camera movement is is too abrupt. I am trying to figure out how to slow the speed of the camera toward the end of the animation whilst leaving it consistent over the rest. Anyone know how to do that? I thought it was in the Dope Sheet but I can't seem to figure out how to change it. Any help appreciated! Demo render: Project file: https://drive.google.com/open?id=1hVTYUs9Q_vtwTNHJaoeJmMadq_O2RUGl Thanks - I'll try to circle back soon but my schedule is currently dictated by the schedule of my baby! Amy
  4. Here's how the final render came out, could def be better but is certainly improved from the first attempts thanks to that collider tag :D https://www.youtube.com/watch?v=i1H00PVrFzg
  5. I was going to reply to your original comment with nice words about our research but it seems to have been removed. It would be nice to have advice for the lab's renders but it doesn't sound like we move fast enough for you. Research is slow and our renders have to come second to the science.
  6. Thank you, that worked! Took me a while to make the additional renders work but finally got it! Hard to find time to render when you're home with a baby. I'm sure you only meant to be nice with that 2nd comment.
  7. I've been struggling with this for a while now - I'm trying to make some cubes float up and bounce off text and neuron branches but when I apply rigid body to the text/neuron they float away. I cannot seem to figure out how to exclude it from gravity. This is definitely a very basic question and I appreciate any suggestions!

  8. Hi there, I'm working on an animation that will show an impulse moving from one neuron to the next for our lab. The neurons in the model were reconstructed by AI from electron microscopy image stacks and the meshes are garbage. So I remesh in C4D with Volume Mesher and Volume Builder, which usually works fine, but currently when I go to render it shows black and freezes C4D entirely. I've been MIA from C4D for 6 months during maternity leave so it's possible this is something obvious that I've totally spaced on.. Any help would be appreciated! Project file. Below are the neurons I'm trying to show before they were remeshed. The topology is so much better after remeshing! Thank you~ Amy
  9. Thanks @DasFrodo! @Cerbera is depth of field not a generic feature of C4D or is it only Octane? Sorry! For what it’s worth when I’ve posted in that category no one answers :/ and the only other octane forum I’ve found from OTOY takes like 5 days to get an answer. Maybe I have chosen the wrong renderer!
  10. Hello there! I'm working to add some depth of field to a neuron animation for the first time and it keeps coming out where the focus regularly and dramatically changes. Here is an example : Here are my camera settings - increasing the Fstop reduced but didn't fix the problem. I am using octane but posting in general rendering as this is a generic issue. Thanks for any ideas! Amy
  11. Thank you, yes adding as a texture worked! working on a closeup version of this now. Thanks! How should I cite you in the video description @Cerbera?
  12. Damn. It might be possible to generate a 3D cube filled with the volume. If we could do that then could I use the subtract modifier to melt it? Each of the images is effectively a plane with xyz coords - maybe I could use a script to hide them in sequence?
  13. You’re correct - I do have a model of the thing to be revealed. We also have the “brain volume” for it to be revealed from, that is the 30k images. Here’s A short version of the scroll. The image in #2 here is maybe a good example of the images stacking into a volume from which we map neurons. The raw images don’t really have a background persay, they are all greyscale. Could we export them as a video and put that in a cube?
  14. Thank you @Cerbera! I’m still confused on how to make the cube show our real microscope images. In the case of the bigger neurons I’m trying to show (see attached image) the cube is a stack of something like 30,000 images. So when it melts away the top of the cube effectively reveals a scroll throug a cross-sectional electron microscope image and the sides would be the edge of our dataset, which is a little more jagged than perfect cube. So would I just take the 30K images and put them under Volume Builder then use Subtract?
  15. Hi all, I am not sure where to post this.. Our neuroscience lab maps 3D neurons. I am trying to make an animation like the beginning of this (from our old designer who worked in Max) that shows a dataset (stack of pngs or video file) that “melts away” to reveal neurons that have grown within it. Is this possible in Cinema 4D? I’ve so far only imported 3D neuron models, which render nicely, but the professor wants one showing the volume of brain it came from and I am totally stuck. Any advice is greatly appreciated! Amy Thanks for taking the time to read. Here are some synapses for you!
  16. Figured it out. Had to set the Shape of the Collision tab of Dynamics Body tag as Static mesh rather than default
  17. Hi, I'm trying to get particles to bounce off of a neuron from our lab. In stead they float right through it. Things I've tried: Rigid body and collider tags on Emitter primitives Collision tag on cell Rigid body on cell makes the cell float away It's probably something wrong with my settings but I cannot seem to figure out what! Any help appreciated! Project file is here. Amy
  18. Ok I finally figured it out. The object defining scatter cannot be hidden from scene. Neurons are scattered on the Surface of a Cube. No cube = no clones. Set the material opacity to zero and voila!
  19. Hey all, New C4D user here experimenting with Octane Scatter to duplicate a neuron from our lab. They show up fine in live viewer but are MIA when I actually hit render. Rener only shows octane sky without the neurons. I've been looking for answers on google and trying to diagnose for a couple hours with no luck. The few answers I have found recommended "check render settings" but I'm not sure what exactly I should be checking for. Here is the project file in case it helps. Any help is appreciated! Thanks Amy
  20. I figured it out! The proper settings for Bloom and Glow are in Octane Camera.
  21. HI all, I am a new user of C4D who makes renders of neurons our lab has reconstructed. We reconstruct 3D neural circuits to model information processing in the brain and I want to show activity across these circuits by having individual cells glow. I spent all day trying to do this and pretty much failing. It's probably (hopefully) something basic I'm missing, but here is what I managed before dinner. This is using Emission on an Octane material. It doesn't look right though. There is no ambient/environmental glow (maybe I have to add some dust or something for that to show up) and it doesn't appear to be illuminating neighbors. Here is a link to the project file in case it is helpful. Here is another failed attempt where I changed the Post settings in Octane for Glare etc but it made all the meshes glow and I couldn't figure out how to apply it to just a single material/mesh. I hope this post is in the right category. Thanks so much for taking the time to read this and for any suggestions! Amy
  22. Thank you! @jed I was using the default bitrate in Standard renderer. The models had too many polys so I have ended up downsampling and re-importing so that I can use a GPU renderer. I will try the export with .TIFF next time.
  23. I rendered this animation of neurons overnight at 1920x1080 Unfortunately the frames look awful! here's a frame comparison from the animation vs a png rendered at the same resolution. What went wrong? Is this because I rendered an mp4 rather than png sequence? In case helpful, here are my render settings, set to mp4. We originally tried octane but the meshes are so complex that we ran out of memory. Any help and also constructive criticism is appreciated. Thank you Amy
  24. Thank you @natevplas and @bentraje ! Using both of these, crucially helpful! Here's a forbidden donut I hope you can enjoy as thanks. It's actually the neurons surrounding a fly's esophagus XD
