How to convert complex brushes to mesh
NOTE: It is easier to select your brushes, then copy and paste into a new map
Also note, i refer to the group of brushes that you want to convert as an object.
Step 0: Make sure you object is suspended in mid air
Step 1: Take your builder brush (red brush) and cover the tops bottoms and sides of your "object"
Step 2: Once the Brush is completely covering the object, press the intersect button (its below add)
Step 3: Make sure you click one of the corners so you have a pivot point
Step 4: Right click the brush tool (which is now in the form of your object) and select Convert > StaticMesh
Step 5: Package: MyLevel Group: Whatever Name: TheMeshIMade
Step 6: Goto your static mesh browser, your mesh is in the MyLevel group (Pull down tab)
