OBS Recording Output
Since version 1.4.0 of the mod you now have the ability to directly output a frame blended game in OBS via a spout sender. This is a good option for people who can't or don't want to record in 240 FPS or more to create smooth gameplay videos. You can now simply use this option and record at a normal FPS rate.
To set this up follow these instructions:
- Download the Spout2 Plugin Installer from https://github.com/Off-World-Live/obs-spout2-plugin
- Run the installer, then enable the plugin via OBS > Tools > Plugin Manager
- In OBS, add a new Source and select "Spout2 Capture"
- Enable the in-game option
Instructions can also be viewed in the in-game GUI.
