C4DtoA 4.6.8 is here!

4.6.8 - Arnold for Cinema 4D

 

C4DtoA 4.6.8 uses Arnold 7.2.5.2 and is a feature release bringing minor improvements to the Arnold Scatter object and the isolate selected workflow in the IPR.

Installation

Cinema 4D Compatibility

  • R25.010 and above
  • S26.013 and above
  • 2023.0.0 and above
  • 2024.0.0 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.

Note: Adding shaders to a Node Material from python crashes Cinema 4D 2024.

Enhancements

  • Shape index via Effectors in Arnold Scatter: The Arnold Scatter object now reads the shape index (Modify Clone parameter) from its Effectors in the new 'effectors' Shape Mode. You can use Fields via the Plain Effector or Cinema 4D shaders via the Shader Effector to control the distribution of shape instances across the surface. (C4DTOA-3010)

  • Instance visibility via Effectors in Arnold Scatter: The Arnold Scatter object now reads visibility from its Effectors. That means the Hide mode of the Push Apart Effector is now supported. (C4DTOA-3011)

  • New isolate selected options in the IPR: You can now choose which type of nodes are filtered by isolate selection in the IPR window. Objects and lights are filtered by default, material selection is ignored. Settings are available from the context menu of the toolbar button and the Render menu. (C4DTOA-3094)

Bug Fixes

  • C4DTOA-3137 - Pasting an aov_write node does not create the AOV automatically

  • C4DTOA-3143 - Viewport preview lost when material has an aov_write shader

  • C4DTOA-3144 - Wrong transform when creating scene objects from a procedural

  • C4DTOA-3146 - OSL shader UI fails to populate combo box with negative values

  • ARNOLD-9734 - Cache and texture flush requests were ignored

  • ARNOLD-14660 - Crash changing imager parameter after disconnecting from driver

  • ARNOLD-14644 - Autobump goes away at extreme magnification

  • ARNOLD-14287 - Rare crash when compiling OSL shaders during IPR

  • ARNOLD-14650 - [GPU] OptiX denoiser renders black when using more than one GPU

  • ARNOLD-14631 - [GPU] Random crash with textures

  • ARNOLD-10216 - [GPU] Log should report why a GPU is not matching requirements

  • usd#1812 - Fix a startup time regression introduced in 7.2.4.0.

  • usd#1753 - Fix a problem with Yeti where the transforms of the ArnoldProceduralCustom were not taken into account in kick and USD procedural.

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 535.104.05 or higher drivers on Linux and 537.13, or higher on Windows. See Arnold GPU for more information.
  • OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.
