How do I get 2 physics materials onto a terrain

I want 2 or more variants in friction at different sections of a terrain but don’t see
how to do this with "physics materials… Is this possible or is there another way (with coding)???

Try to simulate the combined effect on one physic material? You can also script your player to act a certain way when it hits the terrain with a terrain tag, and modify your movement accordingly. Something to think about. -TE
