+Screenshot from VARG (Vulkan Accellerated Rendering Gltf) java based renderer, with background displaying irrandiance map using the included camera viewpoint.  
+At render output, a value of 10000 lumen will equal to max brightness (1.0 in a unorm framebuffer).  
+This value is chosen to match the directional lightsource in the model, having an intensity of 10000 lumen/m2.  
+
+## Description
+
+The purpose of this model is to provide a performance test for a model containing a huge number of nodes, meshes, primitives and materials.    
+The model contains a flat nodehierarchy with 10000 nodes.  
+Each node is referencing one unique mesh and each mesh having one primitive, referencing one unique material.   
+This sums up to 10000 nodes, meshes, primitives and materials.  
+
+In total there are 100 textures in the model (usage of the textures are randomly generated when the model is created)
+
+This model is demanding when it comes to loading and handling a lot of nodes, materials and textures.  
+The goal is to provide a performance test to allow implementations optimize loading, preparation and rendering of such a usecase.  
+It is not intended to be used as a reference benchmark.
