The image’s grainy/noisy look will steadily be reduced until the noise has been removed entirely after an infinite amount of time. The render result constantly improves over time. The fundamental difference between ProRender and older renderers lies in the theoretical "infinite" nature of this process. As the rendering progresses, more samples will be generated per pixel: the result constantly improves. The result (= color) of each sample is continually taken into consideration for each pixel and added to the previous samples in the Picture Viewer and subsequently averaged.
ProRender shoots numerous samples for each pixel into the scene. A powerful graphics card (which is generally already build in) is required.Ĭompared to older Cinema 4D renderers, rendering will not be done in sequence bucket for bucket in the Viewport or Picture Viewer but as a complete image with the noise dissolving as the rendering progresses:.Many common, specialized settings in Cinema 4D (e.g., many of the light settings) do not work due to the prioritizing of physically correct results.ProRender can also render using the CPU, which is slower but makes use of all of the computer’s memory. Always remember to, if possible, use render instances if you have several identical objects in the scene. Current graphics cards are still behind CPUs with regard to RAM, which means that can easily be rendered per CPU with 32 GB memory cannot be rendered on a graphics card with 8 GB of memory.Currently not equipped with all possible features (ProRender is continuously being developed further).The gain in render speed from one graphics card generation to the next is currently much greater compared to the new CPU generations, which promises even faster render speeds in the future.If the graphics card is rendering, the CPU can work on other tasks.A rendering can be judged very quickly due to the comprehensive visibility at the start of rendering (see image below).Rendering is physically correct, which makes it easier to achieve a photorealistic look. Fast rendering compared to rendering with the CPU (for mostly complex scenes) with "integrated" Global Illumination.Here are the advantages and disadvantages of a GPU renderer in short: ProRender can also be used as an interactive preview renderer (can be activated in the view’s ProRender menu). If selected you can render to the Picture Viewer or in the Viewport via IRR. ProRender can be selected in the Render Settings menu. If your graphics card is not compatible, ProRender can also run on the CPU - but slower (this is, however, still in experimental mode!). Since graphics cards are specialized for rendering, they often render much faster than most CPUs.
ProRender is a special physically correct renderer that runs on the graphics card (multiple graphics cards on a single machine can be used simultaneously). All you have to do is have a little patience. This can take a while - during which Cinema 4D may appear to be frozen. Other than in Cinema 4D R19, this is not done for all shaders at once but as necessary, which speeds up the render workflow considerably.
