Corona's Distributed Rendering is intended for simple LAN setups, where all computers are connected using a single switch, so we do not recommend using VPNs. Using DR with a VPN may work, but sometimes may lead to various hard to diagnose issues, such as:
- Render node auto discovery and status reporting (displaying state of the render node and memory usage in the VFB) not working correctly
- Communication between the master computer and the nodes going into a loop of connecting and disconnecting
- Freezing of the VFB until the rendering is finished
- Crashes before the rendered image is saved
If you are experiencing similar issues, but you are not using a VPN, please contact us about this.
