Installing for Maya
When installing Arnold for Maya, follow these steps⁚ download MtoA from the Autodesk Account Portal. Once downloaded, double-click the .exe file to start the installation. If you’re using Windows 8, you may receive a warning message; simply click More Info and then Run anyway to proceed. After installation, configure Maya to use the MtoA plug-in. Note that there is one plug-in for each supported version of Maya and operating system. Additionally, Maya installations with Bifrost Extension include a compatible version of Arnold for Maya (MtoA), but if you have installed a more recent version of Bifrost, you may require a more recent version of MtoA as well.
Installing for Cinema 4D
When installing Arnold for Cinema 4D, follow these steps to ensure a seamless integration⁚ download C4DtoA from the Autodesk Account Portal. Double-click on the downloaded .exe file to start the installation. If you’re using Windows 8, you may encounter a warning message saying “Windows protected your PC.” In this case, click “More Info” and then click “Run anyway” to proceed with the installation.
Once installed, you can access Arnold through Cinema 4D’s render settings. Make sure to check the system requirements and compatibility before installing Arnold for Cinema 4D. Additionally, note that GPU rendering is supported on Windows and Linux only, and requires a compatible Nvidia GPU.
