Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects.
C4DtoA 4.6.5 uses Arnold 7.2.3.3 and is a minor feature release bringing support for Cinema 4D 2024, improvements to the IPR window and to the text overlay settings, and a number of bug fixes. Support for Cinema 4D R24 is dropped.

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
Cinema 4D 2024: Builds for Cinema 4D 2024.0.0 are now available. Since now Cinema 4D 2024 properly applies the view transform to the output, the Bake View Transform option is removed from the Arnold render settings when selecting the native OCIO color management. (C4DTOA-3003, C4DTOA-2959)
Node Material as the default in Cinema 4D 2024: Creating a new Arnold material from the material menu or via commands now creates a Node Material by default in Cinema 4D 2024. If you still prefer the legacy material, you can change the default material system in the Preferences, but note, that the legacy material is deprecated and planned to be removed in the future. (C4DTOA-3069)
Free image alignment in the IPR window: The image displayed in the IPR window is not locked to the center anymore, but can be freely moved around with the left mouse button. When the image is moved outside the window, a small indicator appears at the bottom right corner showing the image position compared to the window. (C4DTOA-2857, C4DTOA-3064)
