The other key change in Redshift 3.5 is the new Redshift Standard material, a new uber-shader “inspired by” Autodesk Standard Surface, the standard material used in 3ds Max, Maya, Arnold and OctaneRender. New Redshift Standard Material simplifies material authoring Maxon group product manager Rick Barrett noted: “ GPU is always going to provide the best performance: that’s why they’re so expensive and difficult to get hold of right now.” The firm says that it plans to iterate on performance in future updates, but that it does not expect Redshift CPU to challenge Redshift GPU for raw speed. However, Maxon describes it as “the first steps to a full CPU version” with “a lot of room for improvement with performance”: in particular, hybrid renders may currently actually be slower than rendering on GPU alone. The initial release supports all of the features of Redshift GPU, with the exception of Round Corners, and CPU and GPU output should be “perceptually indistinguishable”. Rendering on the CPU also avoids two disadvantages of GPU rendering: the performance hit associated with rendering scenes too large to fit into GPU memory, and the high current street prices of GPUs. On the Redshift forum, Maxon notes that CPU support “opens up doors for Redshift to work on CPU render farms”, including commercial rendering services, and the CPU farms maintained by many large VFX facilities. It’s a striking addition to a product whose tagline is “the world’s first fully GPU-accelerated, biased renderer”. The main new features in Redshift 3.5 are Redshift CPU and Redshift XPU: new modes for rendering fully on the CPU, or on both CPU and GPU simultaneously. Redshift CPU and XPU enable users to render on CPU as well as GPU The firm has also announced support for AMD GPUs on Windows and Linux, due in beta in a future release. Other key changes include a new Redshift Standard Material, intended to improve interoperability with other DCC applications and better rendering of thin-film iridescence and diffuse roughness. The update enables the formerly GPU-only renderer to run on the CPU. The video also shows some features added in other recent updates.
