Fixing Bad Grass Shadows in UE4! (READ DESCRIPTION FIRST)

You CAN SKIP the part in 3:33 - 6:46 where we Duplicate the Mesh and simply put this in your Grass Material first (YOU STILL NEED TO MAKE UPWARDS NORMALS) - https://imgur.com/a/2LEZdEL You can also skip when I mention creating Duplicate Faces in Blender from 9:33 - 11:38, basically just ranting about how the backfaces of Normals are always the OPPOSITE of the front face. There are Chapters in the Progress Bar you can use as a guide :) 00:00 Intro 03:33 You CAN SKIP (READ DESCRIPTION!) 06:46 Fixing Diagonal Grass 09:33 More Stuff you CAN Skip! 11:38 Wrap up and shameless Discord Plug HUGE thanks to Divivor for showing me the magic of TransformVector - this saves a lot of vertices! (I'm not entirely sure on how Unreal renders double-sided materials... Either way, it saves the extra set-up time!) Today we're fixing bad Grass Shadows in UE4! This became a real issue for me since I use a global cel-shader (which you can build yourself here:    • Advanced Cel-Shader in UE4 & UE5 [Prismati...  ) A common solution I see online is to set your Material to Non-Tangent-Space and feed a (0,0,1) vector into the Normal channel but you'll soon find that this is only a Band-Aid solution. It only looks pleasant in very specific circumstances and falls apart completely when dealing with slopes/natural landscapes. By making your grass blend perfectly with your landscape you can lower the overall density of the grass, saving performance!
