+Realtime render using VARG-engine (https://github.com/rsahlin/varg-engine)  
+Renderer is using a max light value to scale pixel values before storing in framebuffer (exposure).

+## Description
+
+This is a showcase model containing a couple of IKEA assets assembled into a scene.  
+One of the assets is a light with realistic light intensity values chosen from real products.  
+The scene has one directional light to provide some type of environment illumination, the intensity is chosen to be that of indoor light intensity.  
+A camera is added to represent the desired viewpoint.  
+It is desired that applications render this model 'as is' and not adding environment map, ibl or other types of illumination.  
+
+The model uses KHR_lights_punctual and KHR_materials_emissive_strength extensions.  
+
+Engines will need to use some sort of exposure or light scale factor to limit pixel values to fit within the frambuffer range.
