This is great. Keeping UVs at 90 degrees never occurred to me but it makes so much sense it seems obvious in retrospect
Unless I'm mistaken, this is how Shadow of the Colossus handles the fur on the Colossi
Awesome breakdown Simon!
A student from Digital Arts and Entertainment (in Kortrijk, Belgium) is developing a tool for UE4 to blend static meshes with the environment as his graduation project. With this tool he wants to remove the harsh seam that player sees when a static mesh intersects with a landscape actor.
It was 2016 GDC talk by Dice about Star Wars Battlefront, which presented in-engine tools to blend together natural meshes and the environment, that inspired the artist. In this presentation DICE showcased some in-engine tools to blend together natural meshes and the environment.
I currently have created three variants of this material. One automatically detects the landscape intersection, the second one uses a vertex-paint mask and the third one is a combination of the two.
You can follow the progress on the tool here.
