The final image will essentially be just another checkpoint, rather than a slimmed down image: /prman/checkpoint/asfinal If neither is present it defaults to off. ini setting or a RIB option, with the later overriding the former, you can render a "completed" EXR with the option to continue as if it's a checkpoint. This allows the user to pick up a "finished" image and continue to render. Recently introduced: the ability to mark a final render as a checkpoint. For example: A car render could composite the final render onto a background without having to "bake in" the background to the windows. This allows compositors to use the semi-transparent alpha in later compositing.
Shader writers can take advantage of a new feature to accumulate transparent alpha along the path. With useful controls and the new PxrBakeTexture pattern, artists can quickly generate and use results instead of hand painting maps. PxrDirt is a new pattern made for artists wanting to create useful effects like procedural dirt maps or weathering. It's now possible to assign a different Pixel Variance threshold to individual objects to improve render quality on especially troublesome areas visible to camera rays. Point clouds may be converted to ptex as a post process. This can improve performance by reducing the cost in evaluating these patterns. This allows artists to simplify complex networks to a single result for rendering. It's now possible to bake patterns into 2D textures or point clouds using RenderMan. You can specify the GPU to use by index and adding it to the appropriate. GPU denoising can be enabled by default with an automatic fallback to CPU denoising if no compatible device is available. Using the GPU requires CUDA 7.0 (compute capability 2.0 or later) and a capable graphics card with support. Also, using Denoise with CUDA capable GPUs could reduce Denoise processing times compared to the CPU.
This integrator includes many of the controls artists require for tuning the look of their results.Ĭontinued improvements in performance of the Denoise feature improves speed and quality. PxrOcclusion is a non-physical integrator that can easily and quickly generate occlusion renders for adding details in post compositing work. Scenes with over 1 million lights render more quickly and easily!We also reintroduce an improved Portal Light for difficult interior lighting situations. The lighting services API has also been updated and the new lights take advantage with vastly improved performance. Improved light filters developed in production are included with the studio lighting package. New studio lights from actual Pixar productions are also included to compliment the studio workflow and materials. You may also combine and layer these materials for added flexibility and artistic control. New PxrSurface material used by the Pixar Animation Studios in actual production is now included! This includes solutions for all imaginable effects and are physically based but artist-friendly. Please dive right into the release notes below for more detailed information on the rebirth of your favorite renderer! New Features in 21.0 Scenes using old RSL lights, displacements, and imager shaders will fail to render or render black because of this change. RenderMan is now based on modern and improved pathtracing technology and C++ plug-ins. Please note that the Reyes rendering architecture has been removed from RenderMan 21.0.
