transform this rough sketchup style model into an ultra photorealistic render while strictly preserving the exact geometry proportions layout and camera perspective of the original model do not modify any dimensions shapes or spatial relationships upgrade all materials from basic colors into highly realistic high end materials interpret simple colors as real world materials e g plaster wood stone metal while staying true to the original color tones add realistic textures depth grain reflections roughness and subtle imperfections ensure materials behave physically correct light reflection gloss matte balance apply advanced lighting natural daylight with realistic direction and intensity soft global illumination and accurate shadow falloff realistic contrast and depth enhance realism through micro details and surface variation subtle imperfections not overly perfect realistic ambient occlusion and depth keep the design clean and high end suitable for architectural visualization do not add remove or redesign elements only enhance realism based on the existing model
