• From the render panel of visualize tab, select the drop down of render panel and select the environment and exposure option, turn it on and select image based lightning as dry lake bed.
• From the render panel of visualize tab select the render in region option.
• Type RR in command box, press enter, pick the crop window to create the render.
• Similarly, create the different rendered view of building.
• Select the render window option from the render drop down of render panel of visualize tab and save the view by selecting render in window option and save it.
