Quality
Select the quality. Normally ‘Good’ quality is recommended.
Please note that the better quality, the better/faster computer is required!
Spike remove filter
This parameter determines the strength of which height noise (but also image details!) is filtered away.
A larger value will give a smoother surface.
Step Smooth Strength
This parameter determines the strength of which the height map is smoothed.
A larger value will give a smoother surface.
Radius
Sets the radius within which to compare focus, to calculate the Z height. Radius is the control that sets the size of the analyzed area around each pixel.
Try different values. Start with a small value to see the result. Then, stepwise increase the value to remove noise, unwanted artifacts, or halos along the edges. For scenes with ‘small’ details a low radius of about 3-5 will produce the good results.
