Solid Angle Cinema 4D to Arnold 4.0.1

4.0.1 release note - Date: 24.11.2021
Enhancements
- Material stacking in the Node Material: The end node in a Node Material now has a new alpha input port. Shaders connected to this port (image shader usually) are used as a mix when multiple materials are assigned to an object (stacking). (C4DTOA-2584)

Enable/disable Node Material previews:New options are added to the Node Material UI to enable/disable material, shader and viewport previews. When the material preview or shader previews are disabled, a default Arnold logo is displayed. (C4DTOA-2603)

-Disable material previews in the Preferences:New options are added to the Preferences window to disable material, shader and viewport previews of all Arnold materials. (C4DTOA-2604)
-Disable light viewport previews in the Preferences:New option is added to the Preferences window to disable viewport previews of all Arnold lights. (C4DTOA-2589)
-Default LUT settings in the Preferences:New options are added to the Preferences window to specify a default LUT folder and LUT file. This folder/file will be set in a newly created tonemap imager. (C4DTOA-2606)

-Make LUT mode as the default in the tonemap imager:When creating a new tonemap imager, the LUT mode is selected by default now. (C4DTOA-2609)
-Adjust zoom in the IPR window:When zooming in and out via the mouse wheel in the IPR window, now the zoom changes uniformly (e.g. 100% → 125% → 150% → 200%, etc.), instead of increasing relatively. (C4DTOA-2595)

Arnold is an advanced cross-platformrendering library, or API, developed by Solid Angle and used by a number of prominent organizations in film, television and animation, including Sony Pictures Imageworks. It was developed as a photo-realistic, physically-based ray tracing alternative to traditional scanline based rendering software for CG animation.
Arnold uses cutting-edge algorithms that make the most effective use of your computer's hardware resources: memory, disk space, multiple processor cores, and SIMD/SSE units.
The Arnold architecture was designed to easily adapt to existing pipelines. It is built on top of a pluggable node system; users can extend and customize the system by writing new shaders, cameras, filters and output driver nodes, as well as procedural geometry, custom ray types and user-defined geometric data. The primary goal of the Arnold architecture is to provide a complete solution as a primary renderer for animation and visual effects.
Arnold renderer
Arnold for Cinema4D (C4DtoA)supports most Cinema 4D features such as instances, cloners, deformers, generators, MoGraph geometry, hair, and ThinkingParticles. It also supports both animation and single frame distributed rendering in Team Render, allowing the use of all computers in a local network to speed-up Arnold rendering. Third-party plugins TurbulenceFD and X-Particles are natively supported, allowing artists to render high quality smoke, fire, and particle effects with fully interactive feedback. Other features include volume rendering with OpenVDB, a node-based material editor and a comprehensive list of shaders and utilities, including vertex maps and per-face materials.

Solid AngleSL is the technology company behind the Arnold rendering software, with offices in Madrid and London and customers throughout the world including Framestore, DreamWorks, ILM, Sony Pictures Imageworks, MPC, The Mill, Mikros Image and Rising Sun Pictures. Arnold was designed from the ground up to efficiently raytrace the complex geometric datasets required for feature-length CGI animation and big budget visual effects, while at the same time simplifying the pipeline, reducing the number of passes, minimizing storage requirements and greatly enhancing interactivity for lighting artists.
