You can also try deleting your preferences to clear out any corrupted files. If this is done correctly you should receive a notice on startup that you are using the Minimal Viewport Settings. On a Mac the proceedure should be to close down Cinema 4D, launch it again, then hold down CMD + CTRL + OPT while C4D is loading. The method for doing this is described in your Preferences > Viewport Hardware page. As I'm sure you've noticed, disabling Auto Memory Management will increase your render times by a good amount, so you may have to tweak the memory settings yourself to get the best results.įor Cinema 4D itself you can try launching it with the minimal Viewport settings. Others reported fewer errors when disabling Auto Memory Management in the Render Settings as well. In Redshift, some users reported better performance when disabling Hybrid Rendering in the Preferences. "There are some general fixes that may help, however (some of which you've no doubt tried already). Maxon Support Recommendations & Workarounds: Nonetheless our developers are trying to resolve these issues and have made some progress on the Cinema 4D and Redshift side, and hopefully they should be resolved as updates and releases for those products come out." This is most likely due to the fact that these devices are new and, we suspect, still have some bugs that need to be addressed by Apple, hopefully through firmware, rather than hardware, upgrades. The long version: There are many known issues with M1 Ultra and M1 Max devices which are unfortunately difficult to troubleshoot because they are not always repeatable even on devices with identical configurations. "There is research and development being put into the issues with M1 devices, however it's going more slowly than everyone has been hoping. My last communication regarding this issue. Here's what I was told by Maxon support in December of 2022. Sometimes everything runs great, other times, Redshift has glitches showing up in the final render and other times it will just crash. The Redshift issues still persist on MacOs as of February 2023. So, yes, for now, the best thing is to have all users escalating the issue to Maxon. This is a top priority issue since it affects multiple users, and we are working directly with Apple to get this sorted ASAP. ![]() So it might be worth trying with GI off unless it is vital to the look of your scene. I should point out that after further testing with this workaround, it did take a performance hit.Īs a side note, I got feedback from one of the devs that turning off GI helped in some cases but not all cases. Enabling AMM pushes the GPU harder, and edge cases are more likely to show up. Now the Redshift developer did say: I suspect disabling AMM just hides the issue and makes it rarer, so it's not a legit fix. …since this is a memory issue, I turned off AMM (Auto Memory Management), and that's what worked. One support tech, did extensive tests on a M1 with my scene which is either crashing C4D during rendering or rendering with all sorts of issues (missing textures, cutting through geometry, …). Maxon support is aware of the issue and Redshift Dev are working with Apple to fix the issue in the next Redshift release. Members of the media are invited to review any tools or product suites from Maxon.There are many issues with M1 when rendering with Redshift. Visit the Maxon website for more information. Cinema 4D running on M1 will deliver a world-class workflow experience.” For a 3D artist, these speed and efficiency gains will be invaluable to the creative process. “The new systems deliver industry-leading speed and power, with high performance GPUs. “Apple has a knack for developing groundbreaking technologies and M1 is no exception,” states David McGavran, Maxon CEO. Maxon has a two-decade long history of being the first professional 3D package to support Apple innovations, including being the first to offer multiprocessing on the Mac, the first to support Mac OS X, the first to run on Intel Macs, the first to support 64-bit on a Mac and now the first available for the new MacBook Air, 13-inch MacBook Pro, and Mac mini powered by M1. This makes Cinema 4D the very first professional 3D animation tool available for the new Macs. Today, Maxon announced Cinema 4D will be available for the new M1-powered Macs when they ship.
