Art Asset - Overview / Guidelines

What is an Asset? 
 In a production pipeline, (both animated films and video games), art assets are finished pieces that are ready to be used in a scene. Creating an asset is more than making a model and submitting a .blend file. A completed asset involves all of the surrounding work to enable the next person in the pipeline to effectively drag-and-drop the asset into the scene, and have everything just work. 
 What's expected? 
 For a 3D game, a finished asset includes: 
 Art Source Content: 
 
 A .blend source file for the high-res model checked into the `art-source` repository:
 
 file in the right place with the correct 'snake_case' naming convention. 
 A collection inside the file named correctly for the asset. 
 
 
 A .blend source file for the low-res model checked into the `art-source` repository:
 
 file in the right place with the correct 'snake_case' naming convention. 
 A collection inside the file named correctly for the asset. 
 
 A "collection exporter" set up for the asset saved with the correct export settings, with the export path pointed at the correct location in the `game` repository. 
 
 
 UV unwrapped correctly. 
 Materials assigned correctly. 
 Topology prepared for game:
 
 No n-gons 
 Reasonable polycount 
 other validation. - TODO add more about validation. 
 
 
 
 
 A set of input 'mesh maps' saved as .png files in the same folder:
 
 asset_name_mesh_id.png - ID map 
 asset_name_mesh_world_normal.png - High-res world space normal (16 bit depth). 
 asset_name_mesh_tangent_normal.png - High-res tangent space normal (16 bit depth). 
 asset_name_mesh_ao.png - High-res ambient occlusion 
 asset_name_mesh_curvature.png - High-res curvature 
 
 
 A textures set of baked output textures channel packed and saved as .png files in the same folder:
 
 asset_name_abedo.png - (Color map aka "Base Color") 
 asset_name_normal.png - (16 bit) 
 asset_name_orm.png (Channel packed Occlusion, Roughness, Metallic). 
 
 
 
 In-Game Content: 
 
 A pair of asset_name.gltf + asset_name.bin files exported into the `game` repository via the "export collection" in the source .blend file. 
 One or more materials for the model:
 
 asset_name_mat.tres 
 OR e.g:
 
 asset_name_head_mat.tres 
 asset_name_body_mat.tres 
 asset_name_armor_mat.tres 
 
 
 
 
 All textures from the model's texture set imported with the correct settings:
 
 asset_name_albedo.png 
 asset_name_normal.png 
 asset_name_orm.png 
 
 
 A scene for the asset:
 
 asset_name.tscn 
 Simple colliders assigned:
 
 SphereShape3D 
 BoxShape3D 
 CapsuleShape3D 
 CylinderShape3D - NOTE: this is reportedly buggy, we need to test it before approval, use Capsule instead. 
  If absolutely necessary:
 
 ConvexPolygonShape3D 
 ConcavePolygonShape3D 
 
 
 
 
 
 
 LODs created or generated for the model.
