Intro

Combine primitives, collections, and attribute streams into one export-ready object — fusion before delivery.

Why It Matters

Atlas scenes are never a single mesh. Merge teaches you to think in branches that fuse at the end — the same instinct as Photoshop layer merge, Nuke Over, or joining terrain and buildings in Atlas Logos.

Leaf Meaning

Fuse primitives, instance collections, and attribute streams into one export-ready object.

Blender Examples

  • Join Geometry — fuse snowman spheres or city block extrusions into one output.
  • Collection Info — pull building collections into a single scatter pass.
  • Combine XYZ — merge separate float streams into position vectors.

Cross-Tool Examples

ToolExample
BlenderJoin Geometry combines branches into one output mesh.
PhotoshopLayer merge, blend modes, and smart object compositing.
PremiereNested sequences and multi-track compositing.
NukeMerge node — over, plus, mix operations on plates.
GaeaCombine terrains and erosion passes into final heightfields.
Atlas LogosFuse terrain, buildings, and labels into one scene export.

Atlas Logos Use

Join terrain mesh, instanced buildings, and route curve geometry before exporting a Jerusalem city block or wilderness camp scene.

Practice Task

Build a snowman from three transformed spheres and Join Geometry into a single mesh output ready for material assignment.

Checklist

  • Create at least three separate geometry branches
  • Transform each branch before merging — do not merge first
  • Wire all branches into Join Geometry with readable reroutes
  • Verify one mesh output in the Spreadsheet
  • Frame and label the merge node in the tree
