To create a custom path style you have to edit the template based in: Assets/ParkitectModSpark/Textures. Open the template in any photo editor you want and save it into your project. Create a new Empty Game Object and give it a unique name. Add the GameObject to your mod and set the type to Path Style. The Name and the Price doen't do anything at the moment. Then just select or drag the edited template to Texture and click Create. I will automaticly create the necessary things.
