4.6.3.1

21 Jun 2023

C4DtoA 4.6.3.1 uses Arnold 7.2.2.1 and is a bugfix release.

Installation

• Download the Arnold for Cinema4D plugin
• Follow these installation instructions.

Cinema 4D Compatibility

• S24.111 and above
• R25.010 and above
• S26.013 and above
• 2023.0.0 and above

Note: Known issues in the legacy Arnold Shader Network Editor since Cinema 4D S24:

• Drag & drop nodes to the node editor does not work as expected:
  • Drag & drop an Arnold Material to create a reference. A Cinema 4D Object Operator node is created instead of an Arnold Material reference node.
  • Drag & drop an object to create an object reference. A Cinema 4D Object Operator node is created instead of an Arnold object node.
  • Drag & drop a Vertex Map to create a Vertex Map shader. A Cinema 4D Object Operator node is created instead of an Arnold Vertex Map shader.
• Ctrl + drag a shader in the node editor in S24 creates two copies instead of one. shift + drag and Shift + Alt + drag does not work.

Bug Fixes

• C4DTOA-3005 - Crash in the legacy node editor when docked and the material is deleted
• ARNOLD-13666 - Incorrect opacity on instanced procedural
• ARNOLD-13625 - Fix bias in certain scenes when using global light sampling
• ARNOLD-13618 - Crash when rendering a render region with negative AA and AOVs
• ARNOLD-13643 - [MaterialX] Missing displacement when rendering v1.36 files
• ARNOLD-13576 - [MaterialX] Height displacement is rendered as vector displacement
• usd#1567 - Fix metallic attribute in UsdPreviewSurface in the render delegate
• usd#1550 - UsdPrimvarReader_float2 returning "st" not working in the usd procedural
• usd#1552 - Retain attributes ordering in the Sdr registry
• usd#1548 - Fix RenderProduct arnold:driver ignored in the render delegate
• usd#1546 - Fix relative paths on Arnold nodes

System Requirements

• Windows 10 or later, with the Visual Studio 2019 redistributable.
• Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). This is equivalent to RHEL/CentOS 7.
• macOS 10.13 or later.
• x86_64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chip are natively supported.
• GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ada, Ampere, Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 525.89 or higher drivers on Linux and 528.49, or higher on Windows. See Arnold GPU for more information.
• The cache also needs 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. More information can be found here.
• OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.
