The new "soft" hard shadow is a great addition for realistic renders. Thanks so much Jesse!

And combined with the MC method, WOW, I have no idea about all these new MC options, but the quality is.....WOW...and even without Anti Aliasing!! Is that how Mandelbulber works?

Thanks you for missing me  smiley

just did 2 weeks of intensive programming and this is not what i will do very often...
but i keep on lurking this forum regulary.

I updated the beta because of some issues i found already, check the beta-2 please!

@Bib:
Mandelbulber uses a different lighting with a better ambient occlusion than default m3d lighting, but of course not a that slow rendering method like monte carlo or something.

What is new in version 1.8.6:
  -  Support for loading 48 bit PNG maps and background pics.

Does this mean we can use 16 bit grayscale PNG maps in dIFS heightfield formulas?

Does anyone know of a (bitmap/vector) graphics program that exports 48 bit PNG?

Yes, this should work now, if you have 16 or 48 bit png files that does not work, please report.

Was searching myself for a free program for my tests, but only found cinepaint, a follow up version of a filmgimp? or so... forgot.
But the windows version is a bit crappy, couldnt use it anyhow.

So i am also interested in further suggestions...

Hi Jesse,

When saving as PNG with v1.8.2 I get this error message:

Access violation at address 020313A3 in module MANDELBULB3D.EXE. Read of Adress FFFFFFFF.

After I click OK on the error message box, the PNG file saves OK.  grin

When saving as PNG with v1.86 I get this error message:

Access violation at address 005E3CC9 in module MANDELBULB3D.EXE. Read of Adress FFFFFFFF.

After I click OK on the error message box, the PNG doesn't save, nothing happens.  hurt

All other filetypes save OK without error messages in any version.

Cheers, glad to see you around again.

I would have assumed that. When I'm not terribly wrong, the monte carlo method is similar to the way, some of the "big" raytracers like cinema 4d generate global illumination. I guess this goes beyond mandelbulber's lighting model...
looking forward to test it. grin

Dunno what exact model those pretty renderers use, i only know that m3d makes some simplifications, without them it would be to slow.
But maybe i extend the possibilities furthermore...

Dunno as well, but the stochastic mode is the slowest in c4d too. And it also creates some grainieness...
