i need to enhance my sketchup architectural rendering with vray 5 to achieve a more photorealistic appearance while maintaining all current design elements specific objectives 1 water material enhancement create crystal clear transparent pool water with proper refraction and reflection properties add subtle caustic patterns on the pool bottom to showcase the water depth and the architectural pool design implement a realistic water shader with appropriate ior index of refraction values for natural light caustics ensure the water clarity is high enough to see the pool s geometric design and surface details 2 lighting improvements enhance the natural daylight to create photorealistic shadows and light distribution adjust sunlight angle to create dynamic natural shadows on the deck loungers and surrounding areas implement proper sky dome lighting using a high quality hdri for ambient realism add subtle light reflections on the water surface fresnel effect 3 material texture refinement maintain all existing colors textures and geometric forms as designed enhance material properties concrete deck terracotta loungers greenery with realistic surface details and weathering improve contrast and color saturation subtly without losing the original design intent 4 environmental atmosphere adjust render settings for maximum photorealism global illumination depth of field ensure proper exposure and white balance add realistic color grading and subtle atmospheric perspective render specifications engine vray 5 for sketchup quality production ready photorealism maintain current composition and camera angle
