This will replace the hrothgar fur patterns of your choice with a hand-painted leopard-inspired heart pattern I made. This was a foray into texture/mask learning for me and I hope to expand on it with more fur patterns in the future.
Supported hrothgal models: Vanilla, any Bibo+ body (Rue+, YAB, Tre, Lavabod, etc), TBSE-H 2.0 Supported male hrothgar models: just Vanilla for now (sorry HR3 enjoyers, I played with it a bit but couldn't figure it out yet!)
Make sure to set this mod at a higher priority than your body mod! Since this affects fur pattern mask textures specifically, other hrothgar-friendly body tattoo mods should work fine.
There is also the option to swap your highlight and fur color. It applies to the tail as well.
