I see some beautiful rendering here.  I do not wish to be too much off topic, but here goes.  I use Terragen 2 to render and Carrara.  I recently read about Mandelbulbs and I was hoping to find a program that could output obj files and import them into my favorite rendering programs.  

However, I think that I've been thinking about it all backwards.  A super detailed fractal would be impossibly large.  And of course the closer you zoom, the more coarse such an object would be.  To place objects and fractals into the same world, the proper solution would be to have the rendering program capable of generating the fractal.

I think you or someone like yourself should contact the Terragen programming team or the Carrara one and offer to add that functionality.  The Terragen rendering is awesome by the way.  I'm sure a terrain and atmosphere rendering program would love to have integrated fractal generation abilities.

And then end users like me would be able to render fractals and integrate objects and textures and control lighting, etc, etc, etc.

Actually, those white dots are caused by the specular reflective component of the surface. This component is totally dependent of the surface normal at each point, and the more details we found on the surface, the more perturbated the normal is.
So to get rid of them, I have several options:
- increase the antialiasing value in order to have a better pixel supersampling level, but it takes much longer to render.
- decrease or disable the level of reflectivity of the surface, but I'd look less plastic organic wink
- decrease the number of iterations, so we have less details on the surface, and it'd look softer and less chaotic.

the white dots look a bit random, is it the light source positioned oddly ?!
