Will upgrading RAM or SSD be more beneficial?Īs is so often the case: it depends. While it’s a little bit like comparing apples and oranges, it’s still a common question so we’ll address it here. At this point, 3600MHz is considered plenty enough for most purposes, while 4400MHz is shown in some games to offer a bit more performance, but won’t be that tangible in day-to-day use. The next RAM factor to look at is speed, which again matters up to a certain point but shouldn’t supersede RAM size when buying new RAM. While size is a key thing to consider, you hit diminishing returns once you reach 16GB (and definitely 32GB) in most use cases. Size isn’t the only thing to consider with RAM. And “futureproofing” doesn’t really hold up as an argument because RAM is likely to move onto the next DDR generation rather than keep growing in size. Location of the " Conserve memory (slow)" option in C4D.There’s little purpose for going above that unless you have some kind of multi-monitor, multi-software-running-simultaneously setup. If you're using C4D, you can activate it in Render Settings > Corona > Performance Settings tab. Location of the " Conserve memory (slow)" option in 3dsmax. If you're using 3dsmax, you can activate it in Render Setup > Performance > Performance Settings rollout.
This will slightly reduce RAM usage but will also slow down rendering by about 5%. I am getting a sudden rise in RAM usage! ( 3ds Max | C4D)Īdditionally, the "Conserve memory (slow)" option can be enabled in the Performance settings tab. Solution: Close any other applications running on your computer that could take a noticeable amount of memory (Such as Photoshop, compositing software, web browser with many tabs opened, etc.)įor other possible issues and solutions, see:
Lots of memory-expensive applications running at the time of rendering.Solution: install more RAM (at least 64 GB is recommended for most "standard" interior and exterior scenes 32 GB is the bare minimum). The computer has insufficient RAM installed to render the specific scene.Solution: Optimize scene geometry if possible and reduce the number of objects. Autobump ( 3ds Max | C4D) does that automatically regardless if you're using 3dsmax or C4D. Solution: Use less detailed displacement maps. Regardless if you're using 3dsmax or C4D, you can let the Autobump feature ( 3ds Max | C4D) take care of fine detail. Higher values mean lower quality and lower RAM usage. Usually, the screen size can be left at the default value. Solution: Do not use very high displacement settings unless it's absolutely necessary. Displacement screen size value set too low.Solution: Reduce the number and resolution of bitmaps used in the scene Too many high-resolution textures in the scene.Solution: Enable denoising only for those render elements where it is absolutely necessary.
Solution: Remove any unnecessary render elements, lower output resolution if possible. Note: If you're using 3dsmax, disabling the VFB may also help (Render setup > System > System Settings > VFB Settings > Type: none) however, the memory saving may be negligible. Solution: Lower the output resolution if possible. The same pop-up window will appear regardless if you're using 3dsmax or C4D. This provides the user with information on what exactly should be optimized to lower the RAM usage. Starting from Corona Renderer 3, the "System is running low on RAM" error message will display a breakdown of various rendering components and their RAM usage.
Once memory runs out, the host software (3dsmax or C4D) might either crash or start paging memory onto the hard drive, resulting in extremely slow parsing and rendering (even when using fast SSD drives).
It is triggered by Windows reporting low free memory. This message appears on computers that are running out of available RAM during rendering. You will probably have to simplify the scene." You may experience excessive parsing times and/or crashes. Solution home FAQ - General FAQ - Performance problems System is running low on RAM.
