Full Version: making a displacement more "fluid"

When i displace a gradient with a displacement map, i get slightly jaggy edges.
Is there a way to avoid this ?
Or does it require a higher bitrate image, so that there is more information in the gradient ?

Using 'Adaptive supersampling' when drawing the gradient does not help.
Could be due to round-off errors. Can you post an example?

You can smooth gradients by using Filter>Noise>Spread noise

Here you go

In that case it seems to be how the displacement map works. But working with a higher definition image would make it look smoother.

What do you mean higher definition ?

Is bigger canvassize and later scale down an option ?

Tried it, dies not really improve the situation much.
But blurring before the displacement does.
Blurring the map or the layer?
the gradient layer that is to be displaced
