does a powerfractal mean that things are made not round but broken (fractal) ?

[kasalin]

can one generally say:

a powerfractal makes things broken (fractal) ?

[Henry Blewer]

Depending on how much displacement is used, it can make things look really weird. Use the measure tool at the top of the preview window. This will give you a size for the area/object you are applying the power fractal to. Then you can enter the scale info and displacement numbers so they don't 'explode' things.

I think the fractals in TG2 are all smooth - which makes sense, as you usually don't want discontinuous surfaces.
If you want relatively hard edges, you can use a smooth step scalar after the power fractal:

[kasalin]

ah, thanks .... so I have learned that there is a measure tool ..... cooooooooool tool !!

[Henry Blewer]

It's very handy.
