Double sided normals / foliage issuse.

oxygencube · Dec 2015

Hey all.. I'm working on some grapes in UE4. I am using double sided planes and have the material set to double sided but the back side of the normals isn't correct. It looks like the green channel is flipped... I can flip the green channel in UE or PS but then the front is messed up. How do I get these to render correct on both sides?

SOLVED:

This was my solution... I used the TwoSidedTexturing node to apply a -1 multipled normal map.
