Demo summary

The demo shows selecting a specific perspective in the 3D environment and using a text prompt with an '@' character mention to generate a character (Connor) sitting at a desk within the scene.

Step-by-step

Adjust the 3D environment perspective to a lower angle and zoom in.
Click on the gray area within the scene to select the generation zone.
Enter a prompt using the '@' symbol to call up a specific character.
Click the image generation area to view the result.
Exit the view by clicking the exit button or pressing the Escape key.

Options

Enable the pano image option for panoramic views
Use the generated image as a reference for further editing in Nano Banana 2, Pro, or Cedrian 4.5

Watch out for

The generated image may not be perfect and may require post-production editing.

Tips

Select characters based on their attire to match the scene's context (e.g., a suit for a hotel manager).
Use post-production tools to iron out fine details if the background upscale isn't sufficient.
