Hybrid GPU cards use a combination of self-contained liquid plumbed in and around the GPU chip while letting the VRAM air cool. Air-cooled rigs are the easiest to build, but they are the least efficient, temperature-wise. Many GPU cards are “air-cooled.” These cards have huge fans and heat sinks on board. You do need to keep an eye on your temps. If your rig is running near 100(c) for any length of time, you risk damaging your GPU and VRAM, and will likely cause your computer to become unstable and crash-prone. GPUs will start to throttle performance as temps climb over 80 degrees centigrade. If you have been heavily using your GPU for a while and pushing it hard, you will likely notice that your GPU temp will climb. In certain cases, OctaneRender may try to allocate VRAM that is no longer available, even though OctaneRender thinks it is. And, sometimes, the operating system allocates these resources in a manner that is incomplete, leading to system instability or performance lags. So, while you may have a card with 11GB of VRAM, you may only have 8-9 GB to actually use in your scene.įurther, if other applications are running (such as when you use Adobe After Effects and Cinema 4D at the same time) more VRAM is allocated, which reduces the amount of available VRAM for OctaneRender. These drivers, as well as the operating system in general, tend to take up quite a bit of VRAM on their own, even before you start up Cinema or Octane. They are like little bots that help your computer to draw images to your screen, make calculations, and so on. These drivers are loaded when you first start up your computer, and they reside in your computer’s RAM. Like any add-on product, your GPU card(s) require drivers to operate. There are many different factors regarding instability and GPUs. There are several different factors that can contribute to this, outside of software problems: 2. In some cases, you may experience a crash. Cinema 4D or Octane may become slow to unresponsive. Once you start running into your VRAM headroom barrier, your computer may start to act strangely. Each GPU card has a specific amount of VRAM available (consult with the manufacturer’s specifications for your card(s)). VRAM is consumed by a combination of polygons (your objects), VDB volumes, Octane volumes, materials, textures, shaders, lights, and cameras. Fortunately, it is not a difficult task, but it does require a little attention to detail. Therefore, understanding how to maximize your VRAM is something you need to know how to do. If you exceed the amount of available VRAM, you won’t be able to proceed, and may even experience a crash. Your memory consumption will affect how much you can render at one time. And with Octane 3.0 we provide integration to a beta version of the new Octane Render Cloud to scale for all of your on-demand GPU compute needs.This is one of the most important things to know and to keep an eye on. Attached to your editing tools? No problem! Octane supports more than 21 plugins and has a fully interactive, real-time 3D editing viewport. Use OctaneRender to create images of the highest possible quality at speeds up to 50x faster than CPU-based, unbiased renderers. The release also incorporates important industry standards for GPU rendering, including Open Shader Language (OpenSL) and OpenVDB for particle simulation. Features include volumetric light field primitives and deep motion buffers for high frame rate VR rendering. The release of the new OctaneRender 3, brings new state-of-the-art tools never seen before in any production renderer. With Octane’s parallel compute capabilities, you can create stunning works in a fraction of the time. What does that mean? It means that Octane uses the graphics card in your computer to render photo-realistic images super fast. OctaneRender is the world’s first and fastest GPU-accelerated, unbiased, physically correct renderer. Octane Render for Cinema 4D V4.0-RC7-R4 Win/Mac
