Wow, mclarekin! That menger manipulation is fascinating. It might be good for one of my flights. How much longer than a normal Mandelbox does it take to render?

Don,t know I haven’t looked.  OK,  67 seconds with the  menger,  86 seconds without the menger

But it could be faster or slower with hybrids, it depends on such things as if the extra maths gets to bailout termination conditions faster or slower or the extra maths has expensive functions, (menger is just + and * functions so fast.)

I zoomed into 8.695239557752599e-06, so the resulting image is completely different image  (not similar like the previous example).  With menger was 105 seconds without it was  146 seconds.

So in these cases the hybrid is faster.

How do you get different materials on different shapes? I just downloaded new version today and one issue I have seen if you choose certain materials the fractal just shows up black. Maybe I am doing something wrong?? I have shared the new release on FB in a couple groups I am in... I think a mailing list would be helpful

This is how I have been doing it.

Rectangle at the bottom marked A.

This is where you  start a new material or load an existing.  The active material is highlighted in blue. Meaning it is active in the material editor where you create or modify the material.

Rectangle at top left marked B.

One way to use a material is to go to Global Parameters, click on the material preview image, and the Material Manager UI will appear with the materials you have loaded or created. Click on the one you want to use, then close that UI.
Similarly with primitives, click on the material preview image.And with Boolean Mode each fractal/transform has it's own material preview image when you scroll down.

Hi. I have just returned from vacation, so I'm starting answering your questions and discuss proposals.

It would be cool to see glow in the material editor, so primitives can be without the volumetric glow. Is that possible?
It should be possible, but needs a lot of changes in volumetric shader. But it's great idea to have glow parameters in material editor.

I keep getting grey patches when using transparency, even with spheres etc. Maybe I don't yet understand what I'm looking at.
If you provide any settings file (attach to post) where you observe this problem, then I will tell you what is wrong.

how about distance threshold detail level per material? Or per formula.
I'm not sure if this will be possible with actual ray-marching algorithm. I have to think how to define new conditions for surface detection.

I would like to see accurate light ray behaviour with transparent and reflective materials, so materials act well as lenses and mirrors for moving lights. How cool would it be to use prisms in a scene.
This is very interesting topic. I'm going to do this when I will implement OpenCL in Mandelbulber v2. These effects need much more computation power, so GPU support will be needed. However I'm going to check if this will be also possible using CPU.

Also a "virtual projector" would add huge value. A lot of ideas I have can be solved using luminosity maps, but currently it would be very difficult to recreate a scene where a projector shines an image on a group of objects.
Wow! You are very creative. This would be great effect especially with volumetric light effect. It should be quite easy to implement.

Thank you joe for all inputs.

Do you know when the OSX version of 2.08 will be available?

OSX version is during preparation by @bermarte. Should be released within few days.

A bug with cloud voxel output it puts the files in the folder above the chosen one

Thanks for reporting it. We will fix this error.

I am getting lots of errors "too many errors in settings file" when trying to open the attached fract file (from 2.07). This is on mac version of 2.08.

This is what I get finally past the errors. hurt

That's what it's supposed to be, all the right colors and everything!
Do you have all 158 keyframes too? On my side it refuses to load any of them.
That is my flight #20.  hurt

No, no keyframes at all, the cause of the trouble should be investigated and analyzed next week, I think.  Sceptical

Thank you, I suppose this gives my computer time to render the rest of the flight...  snore
Is it just me or is rendering in 2.08 far faster than in 2.07?

Also, do you have any idea what is causing this heavy noise whenever I use hybrids with mandelbox?
I think I have solved this problem, but if you have an answer please give it anyways  cheesy
By the way, switching between hybrids is very difficult on mac, you have to move them into #1 spot using arrows then move them back. Clicking on them does not work.

@ starmute. Please send an  example fract file   of heavy noise.

Not sure if I have noticed any speed change, but Zebastian has greatly reduced the render time for Rotation of Separate Planes in Mandelbox UI


Edit, Starmute you are correct, it is noticeably faster
@ Joe, I think I know what you mean when using alpha PNG.  There is still some enhancements to do for Materials Manager and this is one of the issues.

I attached the noise sample in my first post but I will do it again. smiley
Do you know about the problem with switching between hybrids?
