Info:
Arnold for Cinema 4D (or C4DtoA) provides a bridge to the Arnold renderer from within the standard Cinema 4D interface.

Features:
? Seamless integration with C4D: objects (instances, cloners, deformers, generators), MoGraph geometry, hair and splines.
? Support for both native particles and Thinking Particles.
? The fastest interactive rendering (IPR) of all Arnold plugins, allows parameter changes to be rapidly previewed without interrupting your work.
? Arnold Shading Network Editor, a node-based material editor.
? A comprehensive list of shaders and utilities, including vertex maps and per-face materials.
? Volume rendering with OpenVDB.
? Deferred, render time generation of geometry with the Arnold procedural node.
? Native linear workflow.
? Team Render, including single-frame distributed rendering.
? Support for third party plugins like X-Particles and Turbulence FD.

System Requirements:
Cinema 4D:
? R21.026 and above
? S22.016 and above
? R23.008 and above
? S24.035 and above
? Windows 10 or later, with the Visual Studio 2019 redistributable.
? CPUs need to support the SSE4.1 instruction set.
? GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ampere, Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 460.39 or higher drivers on Linux and 461.40 (Quadro), 461.40 (GeForce), or higher on Windows. See Getting Started with Arnold GPU for more information.
? Optix? denoiser requires an NVidia GPU with CUDA? Compute Capability 5.0 and above.

Bug Fixes
? c4dtoa#2455 Changing imagers while the render is running brakes the IPR
