====== Validating Geometries ======

Objects that are used in the [[ofp:modeling:lod#geometry|Geometry]] or [[ofp:modeling:lod#fire geometry|Fire Geometry]] LOD must be closed and convex in order to work. 

To test for these qualities you can use the following methods:

**Open Objects** 

Either select the objects manually or find them via\\
Structure -> Topology -> Find Non-Closed 

Then close them via\\
Structure -> Topology -> Close

**Non-Convex Objects** 

Either select the objects manually or find them via\\
Structure -> Convexities -> Find Non-Convexities 

and then close them via\\
Structure -> Convexities -> Convex Hull 

Or, alternatively, apply a\\
Structure -> Convexities -> Component Convex Hull 

on all objects in the current LOD

**Faces/Textures** 

In general it is also a good idea to test for any illegal/dead textures via\\
Structure -> Check Faces
