@Jamsh all you really need to know is here : ://docs.autodesk/3DSMAX/16/ENU/3ds–Help/index.html?url=files/GUID-82722323-100B-4711-A01D-8A87EB53DD96.htm,topicNumber=d30e234498
Also you can find a custom script by google searching that does your bidding 
I think he also uses SlideNormalThief -> you can copy the normals from another mesh to your target mesh
My result didn’t turn out as well 
And for some reason, my foliage isn’t shaded/darkened by the surrounding geometry. Notice how it’s equally bright through the level rather than being darker in the shadowed areas. occurs wether I use a static, stationary or moveable directional light.
Is there anything I’m doing particularly wrong? I used the exact same material setup as for now. My vertex normals are all pointing straight up too.

I think a lot of 's magic is also done with how he made his meshes. did you create your own backfaces rather than using a 2-sided material and use those normals, and are they flat planes or actual geometry with depth?
Are you using static lighting? Foliage doesnt work well with static lighting currently as far as i know.
I know that it only casts dynamic shadows, but changing my light source settings doesn’t seem to change anything… must have missed something somewhere. Even so, that shouldn’t effect the shadowing from the surrounding geometry should it? I’m still not entirely sure how the foliage system works. Might be better to use static meshes for the mean time. That’s going to be a lotta lightmaps though 
Lightmaps are the least of your problem if you place them as staticmeshes. UE3 foliage was lightmapped as well. Never was a big.
Drawcalls on the other hand… The prime reason to use foliage over manually placed meshes are the drawcalls.
You must have something in your material that makes them bright. Try to add a very simple grass material to the mesh just to narrow that if it is indeed the material, or something else.
Using an identical setup to here, I even darkened the colours to no avail, the lighting still doesn’t affect the grass.

The meshes are simple planes with a few extra verts and all normals facing up. 's meshes must be doing something different surely… are you guys actually getting shadowed foliage at all?
Bumping .
Have you placed those meshes with the foliage tool? When yes, then enable moveable in your directional light
Yep I did that, still no luck 
I had to seriously multiply the colour down too, so now it looks too dark all round.
What exactly do you mean by that? Wouldn’t it be a pretty good reason for your shading being messed up when all normals are pointing to the sky? 
Probably they should not face just up.

Look at second picture - 100% dark on polys that looks down and in your case you get 100% bright polys, when they look just up.
here a basic shader without edit normals:

Looking good!
Is there any way you can help explain your wind shader a bit more? My “wind” shader feels more like an underwater current (if that current was having a seizure).
Do you paint weights on the grass?
Looks really ! Keep up the good work! 
Thank you , !
Just experementing with grass shaders.

Thanks . It does actually appear to be working in a new level. My current level has quite a lot of lighting so perhaps a rebuild will help the problem.
Just a shame it’s so expensive to use SSS on foliage
Nope, see 's first post about editing the mesh normals. The idea is to have uniform shading across all of your grass, rather than have normals on the planes that face away from each other.
Again, that’s for a single tree object. On a grass plane, you want them to all face the same way, as the grass is supposed to be one huge object, not a collection of small objects. A quick lighting re-build seems to have fixed my problem, bit odd though.
hey guys, will 's method work for something like :
ok another way without Edit Normals and SSS Shading is, to deactivate the Tanget Space Normal and add 128.128.255 Color to Normal Slot.

I make a short making of.
