Maya 2016 - UE4 - Vertex Normals for Grass (need help)

riuthamus

For the better part of 3 days now I have tried to get this damn grass in UE4 to look properly. No matter what I do I get some odd effects with the normals and shading. I know that previously I would have used the "dome" and transferred the normals from that to the foliage, but that doesnt seem to work either. I have tried to create three faces, angles, everything. Nothing works and I cant get the grass to light without creating this salt and pepper look. Here is a example:


This is with angular grass, 2 sided, 3 planes, and with subsurface lighting (for highlights in the sun)


This is what it looked like for the first attempt in maya:


After I tried to do VNorms facing up and with just two at flat angles, this is the result:


I have been able to get some "okay" looks, but at certain angles it is still very bad.

Bad Angle:

Any help that could be provided would be greatly appreciated as this is something that is "minor" but annoying me to no end. Thanks

Instead of subsurface, try the 2sidedFoliage one.

I did, still left me with the same result. However, if i removed the two sided factor this is the result (much better), I literally tried it right after this post. I felt stupid for posting, but wanted to see if anybody else had some ideas. Thank you for the quick post.
