Learn to use natural text in Fenestra to instantly change lighting, time of day, weather, and overall mood - all from a single image.


Change the weather. Change the story.

Whether it’s something you sketched, rendered, or photographed, once you’ve got an image in Fenestra, you can do a lot with it. One of my favourite things to test is different environments - rain, snow, sunset, night, or even full-on lightning storms. If you’ve got existing renderings from a project, why not try a new time of the year? Great if you’re telling the story of how the project may age or be experienced over time.

Start with a Base Image

Upload your image into Fenestra - or quickly generate something with Sketch To Render. In this example I started with a sketch of a modern villa and then used the generated image as a way to transform the existing time of day, season and environment.

Enter Edit Mode

Select The Conversational Edit Preset

Keep your prompts simple here are a few I’ve used:

  • “Make It Snow“
  • “Change to evening with the lights on inside“
  • “Film photograph, dark atmosphere, night-time storm“
  • “Morning sun, morning dew, long ambient shadows. Crisp atmosphere.“

The simplest of prompts go a long long way, the context is in your input image, provide it with a good high quality image. If you don’t have one, generate one from your base sketch, 3D screenshot or anything you have on hand.

Pro tip: Use the Conversational Edit workflow to create your image just tell it what you want (it does more than edit)

Try a few prompt variations to explore times of day and environments.

Awesome. The captions for the images are the types of prompts i’m using to create each image - give them a try yourself in Fenestra.
