Negative prompts – (worst quality, low quality, normal quality:1.8)
Create a new layer, and draw a smoke line like this.
Go to [Filter -> Blur Gallery -> Path Blur].
Drag each end point to make the path blur to look like this.
Adjust the settings like this.
Add more path points to the line to twist the curve.
When we add points, we must update the settings.
Select the top end point and [Click + Drag] to change the blur strength.
Change the strength for the lower end as well.
This is the end of the tutorial. 🙂
