Reduce render sampling In the render settings, under the Arnold tab reduce the number of sampling set to the applicable fields. Note: Mac automatically updates drivers with OS updates. Once confirmed, ensure that the most current drivers are installed: Finding the Graphics Card Information for Mac.Finding the Graphics Card Information for Linux.Finding the Graphics Card Information for Windows.Update graphics card Find the name of the graphics card, and confirm that the card is on the System requirements for Autodesk Maya list: If a supported processor cannot be implemented, use a different renderer in Maya: Select a renderer. To determine if the processor meets this requirement, find the name of the CPU and search for it on the manufacturer website. Implement a supported processor for Arnold Arnold rendering system requirements state that the processor (CPU) in use must support SSE4.1 instruction set. Make sure you have adequate disk space for your IPR image before you perform an IPR Render.Solution:To resolve the causes listed above, use the following strategies:
IPR images can be very large (for example, at NTSC Video resolution, a single IPR image could be up to 60MB). Since none of the visibility calculations have to be recomputed at this stage, tuning updates much faster than a full software rendering. When you select a region to adjust, Maya loads all the necessary information into memory for all the pixels in the selected region.Īs you modify scene attributes, Maya recomputes the shading calculations and the selected region in Render View updates. The IPR image contains the information needed to perform the shading calculations for each pixel in the image as you adjust scene parameters. It takes longer to perform an IPR render than it does to perform a software render because more information is written to disk. See To batch render IPR files for details. You can batch process IPR images ahead of time from the command line, so you can then adjust several frames of the same animation, in which the visibility data may vary from frame to frame.
