I have an one sided mesh. When i import this into unity i can only see one side. It doesnt render two sided. Is there a two sided material that i can use? Thank you.
Like ZacD said it is better to duplicate the mesh and reverse the normals performance-wise. If you need it for things that are transparent such as hairs you could always use a Cutout Soft Edge Unlit material, they show on both sides. If you really need to get a 2 sided shader, there are some around on forums around the net…
Unless you need the whole model to be double-sided, it's much cheaper performance wise just to duplicate and invert the polygons you need double-sided.
