use the input file as the base render and the reference image as the material guide replace the six columns of the walkway in front of the center building with the rough carved stone rock texture finish shown in the reference image apply this texture only to the six columns and keep the columns the same size proportions spacing and overall shape as they are now maintain the same light warm beige color family as the current render so the new textured columns blend naturally with the rest of the architecture rather than appearing gray or overly contrasting like the raw reference keep the rest of the render unchanged including the camera angle architecture walkway condition surrounding walls landscape glazing lighting and all other materials only update the six columns so they have the texture and character of the reference image while preserving their current color and dimensions
