  1. Hi all. I'd like to simulate the front face of my model (an engine with 300 parts) being cut in half, showing off the inner workings of the engine. I'm not sure what terminology Cinema4D uses to describe this, which has made googling this quite difficult. In my mind, I'd simply create an invisible cube that can slide into the engine model, and anything the cube touches, it makes it transparent/invisible. Any ideas? Thanks!
  2. After looking through my archives from 15 months ago, I found a few 3D Engine models I was provided from work, and I decided to open them all to see if the same problems existed on all of them. Fortunately, the last model I looked at of the 5 I had looked much nicer! I was able to render it in Cinema4D and it had no triangles. So from the looks of things, changing the exporting settings on the CAD software can make all the difference. Unfortuantely, I don't know what those settings were but I now have a test case to prove that I've at least once received a qualitative model from them, so I know that with proper exporting settings I can get a good model to animate/texturize. I just wish I knew what those settings were. (Ideas on how to open two models and see what the export settings were retroactively?). Anyways, video to summarize the thread and I'd like to thank you guys for your time thus far. Case closed!
  3. Woops! I knew it'd butcher your name. First up, I unfortunately cannot share this model as it is not owned by me personally. I imported the model using your recommended settings and it merged all the objects together into one, which was unfortunate - as my model consists of ~300 parts or so. Using your recommended exporting settings, I was unable to get any positive results. There are a lot of triangles, flipped normals, and randomly flipped edges everywhere. I will do my best to reach out to the original designer of these models and see if I can bring in additional file types and/or different export settings. Thank you guys for your time. I'll reply back when I have an update.
  4. Hi all. "Unbreaking Phong Shading" and adjusting the "Phong Tag Angle" value did not change anything unfortunately. Here is a short video summarizing SIgor & javigildd's replies:
  5. When I go into Edge Mode then press CTRL+A, nothing gets selected. If I go into the box selector tool while in edge mode, there is nothing I can select. If I go into Edge Mode, and select everything within the objects manager and then right click the blank space of the preview monitor then finally select "Unbreak Phong Shading," nothing changes. Unfortunate!
  6. Quick aside question semi-related to this. Is there a way to reduce the number of jagged shapes that I see in my model. Here is a screenshot close up: It's really evident on the right side where the shading comes into play. I suspect the actual detail on this model is much higher, but I am unsure how to enable that detail. If I add color to it, it becomes really obvious: Any ideas? Thanks again!
  7. Well well well. Removing those "Normal Tags" looks a lot nicer!!! Cool. So I guess it's off to learning how to add materials and textures. Thanks SIgor!
  8. I opened the .OBJ file in Cinema 4D and here is a screen capture:
  9. Unfortunately it is a model that my company owns and I cannot share it.
  10. This is a render preview image of a model given to me by my co-worker. I'm extremely new to C4D, and could use some 101 tips on attempting to make this model appear smooth. I'd prefer not to have to go back to the CAD program and have the engineer re-export it, but I'll do what must be done. Any ideas? Thanks!
  11. We're making serious progress! So increasing the steps per-frame unfortunately did not yield any results, in fact, it froze the piston in the exact spot it got stuck in with a low torque value. However, reducing the steps per-frame from 5 to 2 seemed to make the animation much smoother! Smooth enough, I think, that I can show this to my boss. Assuming two final things can be addressed: 1. The 90 frame animation look "jumps" ahead when starting over from frame 1. Any ideas where I should be looking to fix the jumping, and the fact that it starts at a slow speed and speeds up? I'd like it to be a consistent speed. 2. The model when going to picture view before rendering shows a lot of triangles. How can I remove them and have a nice smooth model? I am happy to take my own time learning to texture/materialize the piston, but for now the white smooth model will do, if I can remove the triangles. Here is an update video that shows a lot more detail and demonstrates the problem areas:
  12. I got the crankshaft to go completely in a circle by changing the torque to 1000-1500! Nice catch! However, the speed has to be over 500+ and it still slows down dramatically & piston head wiggles a lot when it reaches its lowest point, making the animation not smooth and unrealistic. It was my mistake on my last video about the project settings, by default it was 1 cm, I changed it prior to shooting that video to 0.001 Nanometers to try and save you some time while watching it. The model was indeed done with a different program, "Pro-E/CREO". Finally, if I change gravity from 1000 cm to 5000 cm or 1 cm, there was no difference in the animation.
  13. Thank you Jed for the files and your time. I have an extremely difficult time retaining anything to do with expresso/math/scripting. I've always been poor at math and this is the route I'd least like to take. I spent over 9 hours making this from scratch based off of this tutorial: After all that time, I have zero clue what I did and left that tutorial angry and upset. If I can avoid it, I'd like nothing to do with expresso at all - ever. I don't know what "open an expresso tag" means, or understand what a "clamp" or "target" tag is based off of your last reply, and I apologize for that ignorance. Are those other methods? I do not see any tutorials on this relating to a piston. The method I am using now, seems incredibly simple and it's easy to remember if I can simply get the crankshaft not to get stuck. I'm almost there, it would be great not to start over on a completely different approach. Here is a video detailing my attempts at looking through your reply/attachments. Am I completely out of options to make this piston work without expresso? ...
  14. Thank you Jed for your time and reply. I'll convey your compliments about the model to my coworker/engineer. I've created a video follow up to your suggestion and I've made some progress. The piston head now rotates even further, to about 180 degrees, but still shops short of a full rotation.
  15. Hi everyone. I have a Piston that I almost have working. It's my first ever C4D Animation! My problem is the piston rotates (as expected) for ~30 degrees of it's 360 degree movement, then freezes completely. I'm curious as to why, so I've created a short 2 minute video to hopefully show you what I'm experiencing in the hope that you guys can figure it out with me. I unfortunately cannot share the project files here. Assuming this is a simple fix, I'd also like to remove the triangles from the render as seen here: Hopefully that isn't a huge issue ether, but it is what it is haha. Thanks again all.
