Things You Must do For All 3D Models

Set unit scale to .01 Meters (for proper unreal importing) 

 All models must have -Y as its forward axis 

 Name all objects (RTP_ObjectName) 

 Name all materials (RTP_ObjectName_MaterialName) 

 Pack the .blend file with any textures used, if textures where used 

 Apply all transforms 

 There are exceptions to this rule, do not apply the location transform to: 

 

 Piñata Eyes 

 Broken Meshes 

 Tree/Bush Fertilised Branches 

 

 Apply all modifiers, except the Armature modifier 

 The origin point is at the base of the model and at the world origin 

 It is important that models are game ready. This means the topology should be made up of only triangles and quads. There should also be a reasonable balance between geometry and the level of detail.
