Krea AI: Refining details with the paintbrush and reflective materials

Krea AI Try it →Watch full video →The Architeacher · Jan 2025

Demo summary

The demonstrator uses the paintbrush to add 'reflective glass' and 'concrete wishbone columns,' showing how the tool responds to specific material keywords and manual sketching.

Step-by-step

Select the paintbrush tool
Type a specific material or object prompt like 'reflective glass' or 'concrete Wishbone columns'
Sketch the desired shape directly onto the image
Adjust the color to be more subtle if needed for the material
Move the influence slider to the right to force the AI to adhere closer to the text prompt
Adjust the brush size to control the thickness of the sketched elements

Options

Change the brush size
Change the brush color
Adjust the influence slider to balance between the sketch and the text prompt

Watch out for

The background environment influences the mood and realism of the generated objects (e.g., greenery prompts more realistic interpretations)
Sketches may blend into the background and fail to generate if there is insufficient contrast or specific context

Tips

Treat the process as a feedback loop: sketch, see what the AI interprets, and then work off of those new ideas
Use specific material keywords like 'reflective' or 'concrete' to help the AI interpret the sketch correctly

Highlights

“it's a feedback loop so as you're sketching you're getting ideas from the AI and you can start incorporating them”
