  1. Figured it out. Had to set the Shape of the Collision tab of Dynamics Body tag as Static mesh rather than default
  2. 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
  3. 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!
  4. 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
  5. I figured it out! The proper settings for Bloom and Glow are in Octane Camera.
  6. 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
  7. 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.
  8. 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
  9. 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
  10. Hi, I've been trying unsuccessfully for the past hour to import multiple files into one project. The only way I have found is to use Merge, but that is one at a time. It won't let me select multiple files, and when I drag and drop files into the Objects tab (top r) it makes each one into its own window. I'm with a neuroscience lab and our meshes are quite complex - C4D seems to default import them to >1 km long, so I manually decrease the size, also for each mesh. There must be a better way! Trying to get a hundred neurons or so into one window. Any help would be appreciated! Here's a screenshot from an in-browser reconstruction tool of some of the cells we're trying to showcase. This is called the central complex and it comes from a fly brain. Thank you! Amy
  11. Hi there, I'm learning C4D to make animations of neuron meshes from our lab. Unfortunately it has come to my attention that our meshes are utter sh**. Here is a raw mesh. Steps I've tried to improve them: - quadratic decimation in meshlab - smoothing in meshlab - Instant Meshes Any thoughts?
  12. Thanks! Ok we got this running and played around with exports but it is majorly deforming many of the spines. See how they have become hairlike thin tendrils? Some of them are even severed entirely. This mesh is with 10 smoothing steps and it still looks low-poly. When I try to save a smoothed version out of meshlab, the program freezes entirely. here are the mesh files in case you have any other ideas. Instant Mesh Mesh original resolution mesh
  13. Yeah unfortunately exporting .objs is sort of a hack, and a bad one at that. A ruinous mesh of triangles indeed ha. I imported the raw file into Meshlab and used quadratic edge decimation to reduce the face count by ~50% (it's 1.5M on the full model, and this model is about 1/50th of a whole neuron) so that may be contributing to the low density. But yeah generally the meshes are sh**. I will make a separate thread posting a raw .obj and asking if anyone has ideas as to how I could improve it. I'll give the Subdivide and Smooth options a go. Thank you!
