  1. If you are on a Mac, you might have to download the CUDA installer. It doesn't come as part of the standard Nvidia driver. (This may also be true on Windows, but I don't remember if I had to install it separately or not).
  2. Understood about unbiased renders, thanks. Although I guess the trick is to find the sweet spot of samples, quality and time. Especially when rendering animations. Modo has a convergence bar for it's interactive render view, but that didn't always mean there weren't going to be fireflies when it reached convergence. I though most GPU rendering engines used CUDA, but I guess some parts of it still run with OpenCL. I can always use my MacPro for working and then send renders to a windows render node in the future. Which is the most likely scenario, but I'd still like to wait and see what Apple does first. Yeah, I don't see a bunch of effort being put into Metal right away. Especially because Apple has a habit of inventing software/hardware that they themselves drop support for 5 to 10 years later.
  3. Thanks Hrvoje! I found the comparison tool in the C4d render window. I knew that you could compare renders side to side using A vs B with a slider, but I didn't realize C4d had a built in tool for seeing the pixel difference. The Histogram tabbed helped some with that too. It worked for what I needed. I rendered the same scene frame with four different sample settings (250, 500, 750, 1000). There wasn't huge difference as far as resolution, but the fine details were definitely different. So I'm ending up rendering it with the full 1000 sample resolution that was in the original file I received. I will eventually get a machine with more GPU's. Right now I'm waiting a few months to see what Apple might have to offer with the planned new Mac Pro they said they were working on. If that doesn't seem like a good deal (or doesn't have Nvidia support), then I'll build a Windows box for rendering. Rumors are that they will make an announcement in June. Although it may not be true. I'm on the fence about a high end laptop instead. The laptops I have now are so old they don't even support the most recent versions of OpenGL. The biggest issue with a laptop to me is that it's not easy to upgrade or fix if something goes bad on it. Have a nice week-end.
  4. Hi Everyone, Is there a way to compare two different renders of the same scene that have different sample amounts? I know there is a side by side viewer, but is there a way to get a more technically accurate comparison about what differs between them? Maybe using the histogram? I do have Photoshop too, if that helps. I'm doing some 1920 x 1080 renders in Octane. The original samples were set at 1000. I'm doing some tests at 750, 500 and 250 to see if I can get the render speed down. The 1000 sample frames are taking roughly 5 or 6 minutes. The 250 sample one averages around 2 minutes. The people that are going to use these are projecting them on to really large screens on a stage. So any resolution difference may not matter as much when viewed from a distance. I am not near any of these large screens though, so there isn't a way for me to see what they look like when these animations are being displayed. This next animation has 450 frames total. So the quicker I can render each frame, the better.
  5. Thanks for the advice. I really do appreciate it. I'll do some searches to see if I can find some other optimizations tips. I think the sub has a limit of 2 GPU's, but it's not a problem for now, since I only have the one. If I could stick two GPU's in the older Mac Pro, I would. They just weren't built to handle more than one high end card. At least not without doing some power supply hacking. Within the next year or so I'm going to look in to a new system where I can start with two GPU's and add one or two more as time goes on. Most likely will move over to a full Windows machine unless Apple can impress me with whatever this new Mac Pro is suppose to be. I have Cycles4d, which has me decently covered as a CPU/GPU renderer. Although I've been playing with the Redshift demo and it looks really nice, plus has really good reviews. My main issue is that my work machine is a 2015 27" 5k iMac. So no CUDA for that one. Which makes it where I can only use Octane/Redshift on my home computer. Have a nice night.
  6. Thanks for the reply! I didn't set any of the Octane parameters, they all came pre-set like they are from the motion artist. I haven't had much experience with Octane to know the ins and outs yet. I didn't want to screw up something that was set on purpose. I'll have a look at the adaptive sampling. Is there a reason someone would leave that turned off? There are six different scenes (one of which is actually broken into two parts for some reason). Each one has different Octane settings on it, which I guess is to be expected in most cases. Cheers, Simon Edit: I also tried to post on the OTOY forum before posting the question here. It wouldn't let me create a new topic on there. I'm not sure if it's because I'm a new member there or if it's because I have a monthly subscription?
  7. So I know that depending on the scene being rendered and the hardware, this will vary. I'm rendering a scene set up by someone else and the one I'm currently doing is taking 8 minutes per frame. There are about 250 frames in this sequence, so it's going to take a few days to render at this rate. Latest r20 Studio Updated Windows 10 to most current (I'm using Windows because something is wrong with CUDA on the Mac side) All CUDA and Nvidia drivers are the most current Octane 4 (Latest) MacPro5,1 GTX 1080 Founders Edition 8Gb 1TB WD Caviar Black 7200 SATA III 32Gb RAM Upgraded to Xeon X5690 12-Core (Dual 6-Core) Scene file is 1920 x 1080. I'm just wondering if this sounds about right for a scene, or does this sound like it's taking longer to render than it typically would? I'm new to GPU rendering. Thanks! Simon
  8. Hi Everyone, Sorry if this is the wrong section for this question. I received some files to render that were set up by someone else. They used the Forester plugin in one scene. I let them know that I didn't have that plugin . They are going to bake the tree that was used into an object and then send it to me. How would I go about replacing the plugin tree with the baked one? Thanks!, Simon Edit: He just sent the whole updated file with the trees made editable.
  9. The images were definitely broken in one of the files. C4d never asked for them and didn't tell me the links were broken. When I opened the texture viewer, it showed that it was still trying to look in the path for the person that originally set up the file. Very odd that it didn't warn me the links were broken. Thanks again for the tip though as it saved me a lot of time trying to figure out how to see which ones were missing.
  10. Thanks Hrvoje! I will check for that tag in the files when I get home from work. You've been a great help.
  11. I may have to ask the person that created them specifically which scene(s) they go with. It may just put me back half a day waiting for an answer. I could possibly work backwards and open the alembic files to see what they look like and then try to figure out what matches in any of the scene files. Is there somewhere in C4d that shows all the images used in a scene? Modo has an image tab that shows that, which makes it easy to tell. I have no experience at all with alembic files, so I'm not even sure what to look for inside the scenes that I was provided? I've watched a few videos, and they mention something about a tag, but they never really focused on it in the browser. The three alembic files I was provided all have "Volume_Mesher" in the name and are numbered in a 0, 1 & 2 sequence. Which may be a better clue to someone more adept in C4d. Thanks for all the help you've given!
  12. So I've received some files to render in Octane. The person I got them from has all the textures in one folder and some alembic files in another. I was hired through a PR person, so I have not been in direct contact with the motion designer that created these files. Will C4d ask to load those if it can't find them, or do I need to verify that they've loaded. The biggest issue is that there are 6 C4d files to render. So I don't know which ones contain the alembic / textures and which ones don't (without manually going through each material and object to be sure). Sorry if it seems like a dumb question. I mainly ask because coming from an Adobe Illustrator print environment, I've seen too many people load and print a file when it's automatically replaced one of the fonts they didn't have with Myriad. So just trying to avoid rendering 6 to 8 hour video renders with something missing in them. Thanks!
  13. Hi Everyone, Does anyone know if an Octane subscription can be done for one month only, or do they set it up where you have to subscribe to a minimum number of months? I have a possible client that needs some C4d files that are already set up to render in Octane, but I don't have it. So I'd prefer if I need to use it sporadically, to only rent it for a month when needed. Thanks! Edit: Never mind everyone. I mis-read the wording on their website. It seems the subscription version is already set for month to month. So I can just rent one month if I need.
  14. Thanks for the info! I'll check it out. I want to get a low rez height model of my backyard, which has a steep hill for most of it. I'd like to rough out landscaping ideas in 3d.
  15. So far the Cycles4d is pretty good. My biggest issue is that they only allow one computer activation at a time per license. It would be nice to be able to have at least two enabled at a time since I have a work computer and a home machine. Even something like an auto activation/de-activation option like Marvelous Designer has would be nice. Of course an Internet connect is needed each time for that to work. Edit: Ok so I was wrong. There is a setting in the preferences to automatically turn the license on and off. I'll also say that Cycles seems faster and more interactive than the native built in rendering engines. I haven't compared it to any of the others, but I'd guess Redshift could be faster if using a GTX card.
  16. Thanks, I'll check it out. I'm new to C4d. I've been using Cheetah 3d for about 12 years and Modo for about 2.
  17. Hi Everyone, I tried searching for this topic, but I didn't find anything. So apologies if it's been discussed somewhere already. I'm using a 5k 27" iMac at work, but have a MacPro5,1 with a GTX 1080 in it at home. Is it possible to render remotely from my work machine to my home machine using something like Redshift or Octane? I'm tempted to buy Redshift at some point, but it doesn't help a lot if I can't render from work in one of those rendering engines without an Nvidia card . Any help or info would be greatly appreciated! If not, I may go with Cycles4d.
  18. You may already know about this, or this may be overkill for what you need. I'll post is just in case it may help though. https://lesterbanks.com/2017/02/flocking-simulations-c4d-flock-modifier/
  19. Thanks for the reply and info Cerbera! I'll give the bend deformer a shot then. I'll see about stacking some deformers to get what I need.
  20. Hi Everyone, I'm new to C4d and still trying to learn my way around. I did an animation a few years ago similar to the one I'm working on now. It was done in Cheetah 3d though. I had the same problem in C3d that I'm having here. I have a curved sign that I need to be able to show various inserts being bent during removal and re-insertion. The biggest problems are maintaining the surface area of the part and being able to bend each side independently. Is there a way to make sure the part doesn't distort at all? Can I use a bend modifier with symmetry so I can bend each side independently? I'm linking to the original video I did a few years ago. It's for a different sign product though. The new video will also utilize exploded view animation. Since C3d has a wrap modifier, but doesn't have any way to maintain the surface area. The wrap modifier couldn't be used with symmetry either. So I ended up using an animated spline that I extruded height-wise and gave some thickness to with a shell modifier. I used HotDoor CADTools to make sure the spline length always maintained the exact length I needed to keep in Illustrator, and then imported them. Very tedious method, but it worked for what I needed. I would definitely like some way to do this without having to do that again. C3d doesn't have a dope sheet either, so I had to literally write down on paper to try and sync keys with each other when I had to revise the animation a few times. This is a plan view of the product I'm now trying to match now (size doesn't matter, but the 215mm is the one I'm working on - 3rd from left). http://www.apcosigns.com/ispdf/is434.pdf The suction cup tool in the linked video was done with point animation. If anyone has any Mograph or other tips though that I can use on the suction cup this time around, I'd love to hear about that too. Thanks in advance for any help!
  21. That's a clever trick. I'll have to remember that one. Thanks.
  22. I'm mainly replying to watch this thread. I know that depending on what type of HDRI you're using (if you are) can totally change the color cast of your image. I usually use a studio HDRI that has very little color cast on it. A trick some other 3d friends use is to take an HDRI/EXR that you like and remove most of the color in Photoshop. You may still have to go into an image editor and adjust the color after rendering though to try and target the PMS colors you want. The new Pantone+ palettes all use LAB colors though. Which might make them more accurate on screen.
  23. Have a look at Pepakura Designer. It's not free, but I think it may be what you're looking to do. There are probably more manual ways to do it in C4d. Possibly a well planned UV map, but those can have a distorted polygon surface area from your actual mesh. https://tamasoft.co.jp/pepakura-en/
