Mandelbulb 3D Z Start Tutorial by fraterchaos Mandelbulb 3D Z Start Tutorial by fraterchaos
A little tutorial about fixing "cut off" fractals in Mandelbulb 3D

just a little note, in some cases, unlike the tutorial, you may have to use an even smaller number for the Z Start... in my render "cages" I first changed the Z Start as in the tutorial, just a small amount, but that did not move it enough... I doubled the amount that I changed it, and still the tubes were cut off... I ended up going from something typical like -1.5 to something like -40 or -50 to fix it, so you may find you have to use lower and lower numbers until you finally reach the place you need.

Just remember, negative numbers move away, positive number move closer, and never forget -2 is SMALLER than -1 :)

I hope you find it useful... I believe HalTenny may have also done some tutorials about this and similar things... always worth checking out all his great tuts!

Yes yours was of great help.  HalTenny has been too and his tutorials have been of great help.  And maybe it's just that I didn't know quite how to search for what I saw MB3D doing, it almost always turned up using the Cutting parameters. 

In any case I'm very happy to have found this, thanks again!

I don't understand MB3D at all, but that's why I love it! :D I often use the Z function, when the fractal diappears when zooming in, but often it does unexpected things. I don't mind.

sometimes you can step backwards in the Navi, but that doesn't always work as well, other times stepping is better and Z Start doesn't work as well, but usually you can find one or the other will


most welcome!
