Software Requirements
OctaneRender® for Unreal® Engine requires:
- Unreal Engine Plugin - If you do not own the plugin, you can purchase it on our purchasing page, or you can upgrade your existing license.
- OctaneRender Standalone Edition - If you do not own a standalone license, you can purchase the it on our purchasing page, or upgrade your existing license.
- Matching Version Numbers - License version numbers must be identical (e.g., v2021 Standalone and v2021 OctaneRender plugin).
- Unreal Engine Host Application - Unreal Engine host application versions 4.22 and above for Windows®, Linux, and macOS® or UE5.
OctaneRender for Unreal Engine runs on the following operating systems:
- Microsoft® Windows® 7 - 11 (64-bit) for UE4 and Windows 10 version 1909 revision .1350 or higher for UE5.
- Linux
- macOS® 10.13.6 or higher but note that 10.14 (Mojave) and 10.15 (Catalina) do not support NVIDIA CUDA.
NVIDIA® cuDNN Library File
- OctaneRender requires NVIDIA® CuDNN to run. You can download the cuDNN library file here: https://render.otoy.com/downloads/e5/c5/f2/20/cudnn64_7.dll
- Place the library file in the either of these folders:
- C:\Users\[user]\AppData\Local\OctaneRender\thirdparty\cudnn_7_4_1\
- C:\Program Files\OTOY\[OctaneRender 20xx.x]\
Drivers
OctaneRender requires an NVIDIA® driver supporting at least CUDA® 9.1, and a graphics driver that is version 388.x or higher. You can find the download links for Windows® and Linux here, and the download links for Mac® can be found here. Failure to install these driver versions may result in lack of stability. We cannot provide support to users of different driver versions. It is recommended to install the latest NVIDIA drivers as requirements to run UE5 are more stringent than the requirements for OctaneRender.
The CUDA® driver is the part of the NVIDIA® driver stack that OctaneRender® uses. On Linux and Windows®, it is part of the NVIDIA® graphics driver, while on macOS® systems, it is a separate installation.
If you install any recent NVIDIA® graphics driver on Linux and Windows®, it installs a CUDA® driver that supports CUDA® 9.1. The CUDA® toolkit is only for development, and does not have to be installed. The toolkit includes a graphic driver, but it may not be the latest version.
