How recreate the fractal detail noise from the Heightfield shader

[paq]

Hello,

I really like the extra grainy look the fractal detail can create (last tab from the Heightfield shader).
I'm wondering how this noise is made, as I would prefer to add this detail at the end of my displace shading network.

I know I can use a power fractal, but I'm really not sure how to adjust the settings. (The fractal details comes with 5 settings that my little brain can manage .... mastering the power fractal is an other story )

I'm glad you like it. I often see it suggested that you turn this feature off so that you have more control over the displacement with other shaders, but none really look quite the same. The closest you can get is with a Warp Shader that uses two Power Fractal Shaders plugged into a Redirect Shader (one in the X direction and one in the Z direction) as the warper, but it doesn't really have the same qualities.

I might add a new shader in future that works like the heightfield fractal detail.

Hi Matt,

Thanks for the tip, sounds a little bit like what Martin shows in the webinar ... I'll give a try.

I'll second that  - I really like the Fractal shader but often have to turn it off as it stretches on vertical displacements on heightfields.
