hi everybody,
my english is not very good， to be more clear i will mainly use pictures to introduce。

my Material：

i use this Material Paint a Landscape：

then i use Landscape`s final Material in StaticMesh，it look great,like this:

but i use this in ProceduralMesh is bad,like this:

i was tested the Landscape`s final Material，it use in StaticMesh、SkeletalMesh and InstancedStaticMesh，they are very good！
i wanna know where different between StaticMesh Renderer and ProceduralMesh Renderer ？
I searched in Epic documentation but found nothing really useful for this. please help me!!

Are you creating your UVs for the procedural mesh? My guess is the UVs are not defaulting to anything useful.
