Information about Octane licences for Cinema4d 21, 22, 23, 24, 25, 26, 2023.x, 2024.x

1 - It is node-locked, so it can run on your PC and not on any other PC.

2 - The licence does not expire as long as the hardware is not changed. (CPU, Windows main GPU, i.e. the GPU used for the main display in Windows)

3 - Upgrades are not available later, it works only with OctaneRender [2023.1.R7]
4 - No external internet access is required to install the licence.

5 - If the licence does not work on your computer during installation, we will refund you immediately.

(Rarely happens due to security software on Windows or other operating system issues)

6 - Octane's "online features" are not available, but you can manually download materials to your local library.

7 - Overclocking or changing the CPU on mainboard will break the licence and I will not be able to fix it.

8 - Your GPU should be running fine and not have any driver or software issues.

Supported nvidia GPUs, 10xx, 20xx, 30xx, 40xx
