Using PCG to populate cliffs and rocks on landscape slopes

[BRGEzeHulton]

Hi @Sypher-66 I have an idea that could be helpful for you. Use a Custom Node inside your PCG graph to manually adjust the rotation of each point based on the surface normal.

• Add a Custom Blueprint Node to your PCG graph.
• Inside the PointLoopBody, apply this logic:
• Normal = GetSurfaceNormal(Point.Position)
• Rotation = MakeRotFromZ(Normal)
• Point.Rotation = Rotation

I’m trying to place rocks on the steep parts of the landscape. Which works fine. But most rock assets have a direction, so I need to place them facing upwards. My points are aligned with the landscape, but I need them to also point “up” the slope. Any idea where to start? [image]
