The default red line ground markings are very intense.
This is a small modification of the default texture files. Installing it in the Community folder affects red painted lines everywhere in the world.
This addon does not overwrite or alter default files when installed in the Community folder, but the included texture file will be prioritised when loading.

This is probably unsupported by the SDK, but it seems to work as of December 2020.
It may stop working at any time, please don't yell at me if it does.
Note that the texture file used is made by Asobo and all rights belong to them. I've only reduced the color saturation of the red stripe.

To install drop the "wombiiactual - fadedredlines" folder in the community folder.
