KeyShot 6 Maya Plugin (Mac)
The plugin installs a shelf, which makes it easy to send the scene or updates to KeyShot via LiveLinking. Save the file and configure per scene settings for export and linking.
Keyshot is a pre-requisite for this app and it can be downloaded from https://www.keyshot.com/resources/downloads/
Note: This app uses a custom installer (and not the standard App Store installer).
