Help

Lost my text the first try  :-[
I have no idea what's causing the breakdown of detail and speckly stuff in this image.
I'm hoping it's fixable in how I tweak the settings. Let me know what info about the setting might be helpful
in solving this, and I'll convey them . It's a hybrid of 4 different types, a riff on one of the "examples" .

Thanks,
Dar

That speckly stuff is bad DE (  the  distance estimation calculation aint too good).

As a general rule :  The more you hybridize the more likely the standard DE calc being used will not fit so well.

Reducing Raymarching step multiplier on Render Engine tab may help (but increases render time).  With some hybrids you need to find parameters and location that produces a good quality, and then explore around that region for an image. 

You can always Save your settings to clipboard and post them here or at the Mandelbulber facebook site, and I will advise you if i can:)

I've had some success removing this kind of 'pixelation' by rendering with antialiasing turned 'on'. This does increase render times quite a lot.
I also use Gimp to apply antialising to a fractal render. Also Gimp G'Mic > repair > Remove hot pixels can be useful. :thumbs:
