Asset Loading
All assets are loaded through Urho3D::ResourceCache using resource-relative paths.
The search order is: Data/ → CoreData/ → Content/.
Within Content/, paths are relative: "icons/blupi.png", "sounds/sound001.wav", etc.
Level files are loaded directly from the filesystem using Urho3D::FileSystem::GetProgramDir()
as the base path, not through ResourceCache.
Engine Assets (Data/ and CoreData/)
Urho3D requires its own assets (shaders, default models, default materials) to be present at runtime. These are copied from the U3D or Nova3D engine build output by CMake post-build commands:
Data/Techniques/Diff.xml,DiffAlpha.xml,DiffSkydome.xml,NoTexture.xmlCoreData/Shaders/— GLSL/HLSL shadersCoreData/Models/Box.mdl,Sphere.mdl— basic geometry used by terrain and sky dome
