However to fully handle colored indirect light and emission, the new Shadow Catcher pass should be used. Option for lights to be considered included or excluded, that is if they are real or synthetic objectsīy default the shadow catcher only affects the alpha channel of the Combined pass.Indirect and environment light support, for more accurate compositing.When a small object renders very slowly compared to other objects (for example transparent hair), rendering with smaller tiles can help keep the GPU busy.When there is not enough memory to fit both the scene and render result, reducing tile size makes more memory available for the scene.There are still two situations where reducing tile size from the default can be helpful: Previously tweaking tile size was important for maximizing CPU and GPU performance. For this reason high resolution renders are automatically split into large tiles, and each tile is cached to disk as it is completed. However when rendering high resolution images with many render passes, memory usage can be significant.

The render is now progressively refined by default, giving a quicker preview of full render. ( d18a3b7d18)īefore and after denoiser improvements, click to enlarge. ( c5e5ac4c5e)Īuxiliary albedo and normal passes for volumes were improved, to better preserve volume detail and reduce low frequency noise. A new prefilter option was added to control the denoising of auxiliary albedo and normal passes. OpenImageDenoise was upgraded to version 1.4, with improved detail preservation. This automatically configures the scrambling distance and is the recommended way to use this setting. To automatically estimate a good value, there is an Automatic setting.
This can decrease render times for GPU rendering. Separate presets for viewport and render sampling.Ī new Scrambling Distance setting was added to the Advanced panel which can be used to control the amount of correlation between pixels with a range from 0 (highly correlated, not recommended) to 1 (no correlation).Noise threshold behaviour changed, it needs to be manually tweaked to get comparable results to older versions. Redesigned sampling user interface and default settings.The default sampling settings and user interface are geared towards this workflow, though it is not required. The recommended workflow is now to set a noise threshold (instead of number of samples), and let Cycles adaptively refine the image until the denoiser can eliminate the remaining noise.
