Arnold Render for Cinema 4D 2023 – C4DtoA-4.6.4 (Win only)
Autodesk just released a new version of Arnold. This is the plugin for Cinema 4D 2023.
Simply replace the ai.dll file in the (Cinema 4D folder)\plugins\C4DtoA\arnold\bin with the one provided.
The file has been checked with virustotal and only got single hit which is most probably a false positive.
