Yes, I've already tested it.
In my case, previously I compiled these two add-ons into the one vpk, which is why there was an add-on conflict.
After installing them one by one, I realized that only one of them was conflicting and the other wasn't.
Sorry for the unnecessary panic and thanks for your time! :)

The first addon is already included, basically. The results are not identical, but they achieve the same thing. There's no need to install it if you're already using this one.

The second addon does not conflict with this one. It changes the view model, this one only changes the world model.

Thanks for mods, but sadly there is some conflicts with some of another fixes for Golfclub
Can you make any compatibilities with this addosn or combine your work with them?
