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.

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.

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)

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.
