SOLVED: One side of flat object invisible

[hadece 2]

Summary: I'm looking for a way to make both sides of a flat object visible ingame.

(Sorry in advance if this is described somewhere already, I searched the forums but did not find a solution.)

I'm building an water lily asset made out of flat planes for decent performance. While it looks fine in blender, as soon as I import it into the cities skylines asset editor, one side of my planes is invisible. Some people mentioned this problem already in the past so my question is: Has someone come up with a solution to make both sides of a plane visible without duplicating it?

Help would be very much appreciated <3

Polygons are only visible in one way. If you want them visible in both ways you have to duplicate those polygons and flip the normals.
