  1. No, I am just starting out and google searching / reading enthusiastically about every feature that I don't understand. I am having some trouble getting the right resources, so thanks for taking your time.
  2. Hmm. Later in the docs, they say: If you take a look at the curves above you will notice that several curves (Mitchell, Cubic and in particular Sinc) even fall below zero. This means that at corresponding edges, contrasting color values are rendered that are not even present in the scene. This makes the edges look sharper. So apparently they are not ignoring it, but somehow replacing it with whatever "contrasting color" is.
  3. I am reading documentation on antialiasing and I don't fully understand how filters work. https://imgur.com/a/R5frOiO "Take a look at the center pixel. 16 sub-pixels were used to calculate this pixel. 15 are light gray, 1 red. These pixels form a curve. Imagine this curve as flat around the center of a pixel. This curve then defines the degree of influence each sub-pixel should have. Because the filter size (Filter Width setting) and Filter Height (i.e. the spread within which sub-pixels will be taken into consideration) can be expanded to up to 4 pixels, the curve can be made to spread out quite a bit more." Each pixel color will be calcualated based on the colors of subpixels inside the same pixel. In all off the curves the center subpixel has the most weight in calculating color. The weight falls of with distance, and even goes below 0. I don't understand how exactly color calculation is done, because some of the curves go below x a-axis. If the clipping was always done, than it would fit my mental model, but I don't get how a negative weight works. Is it like, "substract this color" ? I'd appreciate if someone can explain this topic in their own words. Cheeers

    Cinema 4D mentorship

    Thank you all for replies. I really appreciate it. I am looking for concrete learning paths. For example: take course x, than y, followed by z, u, v, read book B and so on. I have no official art education and almost zero experience with c4d. To paraphrase: How would you learn 3D, if you had to learn everything you know again from scratch? Where would you start, what wouldn't you do?

    Cinema 4D mentorship

    Hello everyone! I'm a rookie in this vast 3D world. i'd like to explore it in great detail. Being a self taught software engineer, I learned the value of mentorship the hard way. I've used so many bad workflows, done so many stupid mistakes and wasted enormous amount of time fixing them. In almost all cases, I didn't really understand what's going on and was missing some crucial logic needed to perform the task. Fast forward to today, and I am on a new very exiting journey. I've got 500hrs in the next two months, that I'd like to spend on learning cinema. My desire is to master motion graphics and photo realistic product design. These are some examples that I'd like to be able to create: https://streamable.com/gkyjy , https://streamable.com/yd6cz. I looked at https://www.MAXON.net/en/training/online-learning/ for starting points and completed Lynda's "Essentials training" and Greyscale Gorilla's "Introduction to c4d", but I am left with more questions than I had before. There is so many settings and effects left that I don't understand as good as I should. Tutorials just jump into adjusting sliders without providing sufficient background on the topic. Often, many settings work hand in hand and I find myself randomly adjusting each one and hoping for a good result. Very reminiscent of my early developer days. What learning path do you recommend that I take? What is an efficient way of learning realistic motion graphics? I really want an in depth understand of the tool, and it's many features. Adjusting the sliders without knowing exactly what I am doing will just left me miserable. I have a little to zero background in 3D stuff, but I am comfortable with After Effects and Photoshop. Thanks for all your tips. Cheers, Mitt
  6. Hi everyone! I am looking for a c4d expert to create realistic animations of mobile device and environment in which it is put. You’ll originally create 4 different scenes with different environments and then build around each environment for a total of 20 4-6 seconds long scenes. I *think* that once you setup the initial scene for each environment, you will be able to move pretty quickly since the build-arounds will be done with lots of camera movement and small modifications to the environment. I’ll supply you with the phone model. Take a look at an example: https://streamable.com/yd6cz. Phone is set in an environment and than multiple scenes are created. It sets a good example, even though scenes are a little short and the focus should be on screen and not the design of phone itself. I’ve got intermediate knowledge of After Effects and basic skills in c4d so we will be able to have a professional discussion. C4dcaffe offers PMs, so please send me one if you are interested. Thank you! Mitt
  7. Ahhh, increasing GI settings totally did the trick. Sorry for the poor choice of words. The thing that was bothering me is that noisy grain you can see in white part of the phone. Thanks guys, I am seeing much better results with GI accuracy increased
  8. Hey everyone! I am playing around with an phone model I found online. I'd like to change the color from black to white, but changing color causes some weird pixelation. Take a look at the images. I do not know weather this has to do with render settings or materials. If you need to look at the source project, you can find it here https://www.dropbox.com/s/cb8ns8bqy4ua2lv/q.zip?dl=0 Glass Black is the name of the material I changed to make the phone front white. How can I avoid this pixelation? Thanks for help!
  9. Thanks for stopping by. i've got 3+ years of experience, mostly in the app and web world. Even though I've spent so much time programming, starting out with C4d programming is probably the most terrifying experience I had, mostly due to lack of good learning resources. So basically I'd like to run a command line command, and tell cinema to open up a file fiddle around and save it. To do that I need to write a plugin, yes?
  10. I'd like to explore cinema 4d programming. Like opening a file, fiddling around with some objects and closing it back. Something like ActionScript does for the after effects. Right from the start, I am subjected to 3 different programming languages/libraries which can be used. Cinema is enormous program, so the SDK must be enormous too. Can you help me out choosing the right tool I learn to use for my use case?
  11. Thanks. Can you do a quick render of 280. frame? Does it match with the one in Active Render region?

  13. I am developing a clouds animation. The camera is moving to give it a sense of flying and under pyrocluster material -> noise, I animate Phase, so that the clouds are changing shape slowly. My problem is that approximately 1% of frames are totally wrong. By that I mean, that the transition from previous frame to the next is abrupt. The clouds are in some strange position and not connected to previous state. Also, around 0.4% of frames don't even render clouds. It just renders the sweep nurbs plane, to which clouds are attached. Check this image below: I am rendering the same frame, but in picture viewer it is totally different. What should I do?

    Multipass rendering issues

    Thanks for stopping by. I switched to that, but no difference. Also, only the combination of multipasses does not look correct. Regular image render looks good in AE. It is like a top reflectance is missing in the multi-passes. hmm
  15. I am rendering a mobile phone. The goal is to create a sandwich with mobile phone without reflections at the bottom, screen with image applied in AE in the middle and reflection at the top. For that to happen I need to render "regular image" without reflections. How can I do that? I disabled regular image in the Save tab of Render settings and choose Add All under right click on Multi-Pass. The render I got after compositing in AE was waay off the one I rendered in cinema 4d picture viewer. c4d: http://imgur.com/a/qZofJ AE: http://imgur.com/a/oSKiN This is the file to play with: https://ufile.io/sebog Thanks for your help.
