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. Render attributes such as camera depth of field, motion blur, reflections, refractions, and indirect light all have to me optimized effectively.Īrvid steps through some of the relevant settings when optimizing Arnold for both IPR and final renders, with his new 2-part series.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. Scene dependant qualities will affect render times and render dependant attributes will affect the noise in the scene. There are certainly a lot of things to consider when optimizing Arnold (or any renderer). Optimizing Arnold for both will provide a much better experience as well as cleaner renders in the end. There is the IPR, or interactive preview render, while you are working. There are really two streams for optimizing a rendering workflow.
If you are using Arnold as a render engine (which is the same in all hosts) Arvid Schneider offers some great tips for optimizing Arnold. Why spend time waiting for projects to render when you can spend a bit of time optimizing for faster and cleaner renders. No matter how fast your system or renderer of choice is, everyone is looking for faster renders.
