8/3/2023 0 Comments Maya 2022 optix denoiser0 preserves the input untouched and 1 applies the full node effect (ARNOLD-11172). Imager_tonemap.mix: imager_tonemap now has an additional mix parameter. RGB colors edited in real-time using imager_color_curves.Curve interpolation and working color space can also be set as needed (ARNOLD-11161). Separate curves can be authored for each R, G, or B component, along with the main curve to control the overall luminance response. Imager_color_curves: A new imager to control brightness and color curves has been added. Arnold on CPU will now automatically force a box filter on outputs with filters with known issues when either of the denoisers are used (ARNOLD-10812). To help with this, it is possible to specify a working color space in imager_t_working_color_space to convert to the specified space, apply the lut, and convert to linear or rendering color space again (ARNOLD-11084).Īutomatic selection of box filtering with OIDN and OptiX denoisers: The OptiX and OIDN denoisers do not perform well with CPU rendering filters that span across multiple pixels. Note that some LUTs assume a non-linear color space. imager_t_filename specifies the file to load. LUT based tone mapping: imager_tonemap now supports a lut mode to apply LUT files in all the formats supported by OCIOv2 ( cube, look, 3dl, clf among others). Sima_as3_albedoD_optix sima_as3_albedoS7_denoise.optix sima_as3_undenoised Undenoised Optix diffuse albedo Optix diffuse+specular albedo Below are comparisons between undenoised and Optix denoised with the old and new albedo AOV (ARNOLD-10812). This adds specular reflections and refractions to the albedo, which can improve denoiser quality. Higher quality AI denoising: The OptiX and OIDN denoisers now use the newly introduced denoise_albedo_noisy AOV as the albedo feature AOV provided to the denoiser. Open Image Denoise imager: Intel®'s Open Image Denoise (OIDN) is a fast, AI-accelerated denoiser that runs on CPU that has been integrated into Arnold as the imager_denoiser_oidn imager as an additional denoising option. (ARNOLD-8677). By default, MtoA uses the scene units defined in the Maya Preferences. ass file will now appear with a different scale if the current scene units are different from the ones used during export. This allows loading the file in a scene having different scene units, with consistent results. Scene Units: When exporting scenes to Arnold, the scene units defined in the Render Settings (System) are now stored in the. Users can also perform file operations like export to scene, render to texture in parallel to rendering. Parallel preview renders on the CPU: MtoA can render the Material Viewer and the swatch in parallel with the primary render in Arnold Render View or Arnold Viewport. MtoA 5.0.0 works with the following Maya plugins Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above. We recommend using the 470.74 or higher drivers on Linux and 472.12 (Quadro), 472.12 (GeForce), or higher on Windows. See Getting Started with Arnold GPU for more information. GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ampere, Turing, Volta, Pascal, or Maxwell architecture. This is equivalent to RHEL/CentOS 7.ĬPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chip are supported under Rosetta 2 mode. Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). Windows 10 or later, with the Visual Studio 2019 redistributable. MtoA 5.0.0 introduces Arnold 7.0.0.0 and is a major feature release bringing parallel preview renders on the CPU, multiple outputs for OSL and custom shaders, brand new imagers along with many other enhancements and bug fixes.
