Add random (z-vector-values) to Procedural Mesh Grid

Hello,

I recently followed a tutorial on the procedural mesh component. At the end I was able to create a grid mesh with a controllable about of quads. I am now trying to displace this procedural grid with vector data (whether this be with Perlin 1D, or converting heightmap data to a z vector array). Attached is the construction script I currently am working with.
