No Tutorials that I could point to right off the top of my head. Probably someone has one over at DA somewhere, maybe Hal Tenny or someone, mostly all tricks and Tips for MB3D are gleaned from threads in the Mandelbulb3D threads at FractalForums.com.

 

A few tips on Reflects and Transparency(refractions)

Good reflects need smooth surfaces, rough and uneven surfaces cause massive light scattering.

Reflection settings 

Ammount = reflects/light strength, typically you don't need more than 1

Depth = amount of reflected data, the higher the deeper the reflected area(more detail) also the longer the Reflects render time.

Reflects Rendering is a seperate render from the main image there fore before doing reflections if you want a faster Reflects Render you can change the Main Image render settings, it won't affect the main image but speed up the Reflects Render time.

Fog also affects Reflects so keepm that in mind, also too much ambient or Difuse lighting will cause Reflects to be washed out.

TRANSPARENCY doesn't work well on escapetime Formulas, d.IFS fromulas are the best for transparency. Transparency of gradients are set using the Obj Diff light/gradient sliders. Open it and the top third section on the sliders control the Transparency of the gradient 1=solid 255=Fully transparent.

Any MB3D with transparency and or reflections and has the Params posted with it you cah load those params and see what they used for settings to make them work

Also the Readme file has some tips on Reflects/Transparencies

Hope that helps a little anyway
