Grass not Matching Terrain Shading

[BramSteijn]

To fully match grass shading, you need to make sure that grass’s basecolor, normal, roughness, specular and ambient occlusion match terrain. That implies reconstruction whatever you do with landscape, in grass material.

Commonly, it is just enough to blend grass world space normals from terrain normals to grass normals from grass card bottom to top. Luckily, your grass instances are placed perpendicular to terrain, so up vector in instance local space will give you terrain normal in world space.

Hello! Thank you for your reply! I did try matching those settings across the two different materials. I even went into the buffer visualisation to make sure they are actually matching.

Unfortunately, I am an art major (literature, not even game art :P). I have no experience with this kind of stuff, so while I have read enough to understand the difference between world normals and local normals, your last two sentences sound like something out of a Sci-Fi film to me - which sucks because if I understood, I might be able to fix the issue

Okay, as I was trying to explain what I was doing (grabbing a vector 3 (0,0,1) and hooking it up to a transform node and connecting that to the normal channel in the material node) and how that was not working, I found out that I was using the wrong transform node It is working now Hurray! I do still have to fine tune it, but I have made some progress. Thank you again!
