The new model adds two new parameters, scatter_secondary_anisotropy (in ) and scatter_secondary_anisotropy_mix (in ). This provides a more realistic approximation to the physical phase function of scattering media such as clouds. The new crop render tool allows users to select a crop region without needing to render a full viewport first (MTOA-1006)Īrnold Render View by Default: The Maya Render View has been replaced with the Arnold Render View for Arnold Renders and IPR, except for Render Sequence (MTOA-1008)Įmit Specular & Emit Diffuse Options on Maya Lights: This version adds support for the native Emit Specular and Emit Diffuse options on Maya lights (MTOA-1086)ĭual-lobe phase function for standard_volume: A new phase function model has been implemented for the standard_volume shader, which is a mixture of two lobes rather than a single lobe as before. Viewport rendering improvements: A new toolbar has been added to all model view panels to make it easier to run and control the Arnold Viewport Renderer. MtoA 5.2.0 works with the following Maya plugins The cache will also need to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver, or changing the hardware configuration of GPUs on the system. In the driver page select "Windows Driver Type:" DCH We recommend using the 511.09 (Quadro), 511.09 (GeForce), or higher on Windows and 495.46 or higher drivers on Linux. See Getting Started with Arnold GPU for more information. Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above. 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 chips 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 5.2.0 introduces Arnold 7.1.3.0 and is a minor feature release bringing improvements to volume shading and viewport rendering.
