About This File
This export preset is for easily exporting materials painted using ArmorPaint for Ultra Engine. The diffuse color, normal will be exported and the ORM texture will have the masks in the correct channel.
The only thing this doesn't support is emission textures.
To install, place the ultra.json file in your data\export_presets directory of your ArmorPaint installation. If you're running ArmorPaint on macOS, you'll need to open the ArmorPaint application as a folder and insert the file within that. (Importing presets on macOS crashes the application.)
