# Wireframe

## Specifications

* The wireframe should be the exact same mesh from the LOD\_0
* The only noticeable difference is the material configuration

## Characteristics

* Transform Y Up
* Mesh should include tangents, normals, UVs
* Compression level: 6

## Objects

* No Light objects
* No Camera objects
* No Empty objects
* No Animation objects

## Positioning

* Origin: \[0, 0, 0]
* Scale: \[1, 1, 1]
* Rotation: \[0, 0, 0]
* Max X Offset (width): 0.01
* Max Y Offset (height): 0.01
* Max Z Offset (length): 0.01

## Materials

* Wireframe material should use Blender Principled shader with the following specs:

  * Metallic: 0
  * Roughness:1
  * Alpha:0.5

* For the Alpha to work, it is important to activate eevee render render engine in the render properties tab

* After this be sure to activate the Alpha blend on the Blend mode at the settings in the Materials properties tab

## UV Maps

* Do not leave unused areas
* Avoid stretched images
* If the model is symmetrical or has any repeated mesh or shape, these should be overlapped
* Include a 10px bleed for the UV islands
* Any UV island with flat colors/textures should be overlapped 
* Keep UV island size relatively scale according to the actual size of the area
* Avoid any stretched or curved sections for cylindrical shapes UV map

## Size

* Maximum Width 260 meters
* Maximum Length 260 meters
* Maximum Height 100 meters
