Machinist:
It's kind of vague from your posts, but I'm gathering that you want to be able to run the R8 Mod, add new sets of liveries with Custom Livery Tool, and customize the starting grid for a race with Custom Grid.
To do this:
- Activate the R8 mod, test that it works.
- Install Custom Livery Tool.
- Activate the Custom Grid Tool_CL (the release for use with Custom Livery Tool).
- Run the Livery Tool, assign the sets of liveries you want.
- Run the Grid Tool, assign the grid that you want.
I'm fairly confident that should work. Admittedly, I haven't done a whole lot of testing with using my tools and addon cars, but I've done my best to generalize the functions in them so that new cars would be handled appropriately (so I wouldn't be re-writing my code every time SMS released an update), so I would expect them to work. A lot of these mods access the same files, so you have to be careful about the order in which things are done to get the desired outcome.
Hope that helps.
