Legacy Reference

Modify Tools

This topic references tools and features that are legacy. If you want to use legacy tools in Lumberyard Editor, disable the CryEntity Removal gem using the Project Configurator or the command line. To learn about the latest features, see the Amazon Lumberyard User Guide.

The following buttons are available from the MO tab on the Designer Menu panel.


Used to smooth edges of a shape. Most shapes have blunt edges, so applying the bevel to edges of a shape can add more realism.


Select at least two objects, and chose either Union, Difference, or Intersection.

Array Clone

Places cloned objects evenly in a line.

Circle Clone

Places cloned objects in a circle


Used to create a mesh by extruding each edge of a profile polygon along a path. You can make a complicated model using this method.


Used for cutting quad-shaped polygons by several loop edges. Set the direction and number of loops. The direction of the loops are set by the edge closest to the cursor and the number of loops are changed by moving the mouse wheel while pressing the CTRL key.


Deprecated (merged with the Lathe function).


Used to mirror a mesh along an arbitrary plane as well as its local x-, y-, or z-axis plane. This tool has the following functions:

  • Apply – Splits a mesh by a mirror plane and copies the half part to the other part and then starts the mirror editing.

  • Invert – Invert a direction of the mirror plane.

  • Center Pivot – Moves the pivot position to the center of the bounding box.

  • Align X, Align Y, and Align Z – Aligns the mirror plane by x-axis, y-axis, or z-axis.

  • Freeze – Freezes the current geometry.


Used to create a smooth appearance of a mesh without complicated manipulations. A control mesh made this way doesn't need many vertices or faces to model complex smooth surfaces. You can also give each edge a semi-sharp crease, which defines how sharp each edge is.
