devonmousseau polycounter lvl 4
Hey guys, I've been struggling with this for about 2 days now. Tried to watch the unreal material series at their website but it didn't really delve into foliage.

So, I've made this grass, and I'm happy with how it turned out. However, I don't like the way it receives light from the side the light is not hitting directly.

Light directly contacting:

Back side:

Thanks in advance!

    Are you using the 2 sided foliage shader? Can you post the material?

    You need to have the textures not selected so I can see the material details on the left, can I see what the material looks like in the material editor with the 2 sided foliage material?

    With 2 sided, plug the base color texture into the subsurface scatter color as well as the base color. Also try using roughness instead of specular, but invert your specular texture before plugging it in there. Also try looking at the material in the scene with AO and no AO, your AO texture might be a bit strong, but it might look good in certain situations.
