Texture issues one double sided planes
I have a female character with long dress and long hair meshes that are made of planes facing both directions but, the lightning of those areas have some issues (high contrast, looks like harsh normals). I could try using double sided planes for her hair (although I couldn't find how to do that on just one part of a skeletal mesh, only on a static mesh) but this wouldn't work for her dress that have different textures on the inside and the outside.
I don't think the issue is with my textures since the parts of her dress on the torso and her hair bangs don't need this backfacing and have no issues even though use the same material. I think it's some option for material rendering that I'm missing.
Sorry if this has been answered already, I looked around and found similar questions but with solutions that didn't solved my problem.
Two sided sign material expression is your answer.
