Project Template for Substance Designer
This is a simple starter template for designer projects, with a custom node for toggling between both Unity's and Unreal's default mask packing.
Make sure a path to the directory of the GameMaskPacker file exists under Preferences -> Projects -> Library Also ensure a path to CustomDefault under Preferences -> Projects -> General -> Template Directories
Personally, I have a folder for "Designer Library" with nodes and whatnot and a subfolder for templates, and just throw all my things in there as follows:
Provided your librarys are all set, just make a new project and your template should be one of the options
On export, just toggle off the "Materials" section if you only want the useful stuff, as they're for automatic viewing's sake. One thing to note is that I pack Height into the non-RMO channels of the masks, but I distributed the sbs so you can change whatever you like
