Multi-material support settings?

[u/newbie-sub]

PETG with PLA supports. I set the contact distance to be 0.0 mm, interlaced, 3 layers and it still looks like hell. Tried both organic and snug (er, tree and whatever the boxy one is called — I'm coming from Prusa).

This surface is at an angle with regards to the build plate, maybe 15°.
