Hey there @ripchan! How does your material look for those planks? This could be caused by a low roughness value, but it doesn’t seem like reflection. To me it looks like it could be lighting lighting related. Errors like this can sometimes occur with built lighting. Does rebuilding your lighting change this?
hey my roughness is set to 1.0 I had a feeling it might of been lighting related issues I did rebake the landscape lights and it didn’t fix the issue I also tried using the skylight and directional light I had in another project where it doesn’t have that greenish shadow but sadly that still didn’t fix the issue what I have noticed however if I place something directly under the affected mesh the problem goes away so what I ended up doing was use a dirt texture for my landscape around the static meshes and that got rid of the green from the grass at least now it looks more neutral
