Thanks for the new version. Nice to see, that also the feedback situation is gettig better. In principle the new version works fine.
I encountered a redraw problem, I already saw some times in previous versions. When triggered, the fractal does not redraw anymore, until you resize the window or change to annother window, regardless of the status (still rendering or finished).
Unfortunately I was not able to reproduce it. It seems to appear unregularly. So, don't take it as reason to delay the next build. It is not that serious and can be solved by restarting the program. My System: win 10 home.
Keep up! grin

@ taurus, can you remember with what version you first noticed this problem.  Also similarly the progress bar can have the same problem.   We have been monitoring this non-critical problem but have yet to determine what causes it. 

@ starmute. I am looking forward to viewing it smiley

Mclarekin, I think Taurus' problem has occurred with me too. It seems to happen when clicking the 'rotate' buttons rapidly.

I have a couple non-essential suggestions:
- Allow multiple Mandelbulber windows, and setting weight for each one. So if window A has weight 4 and window B has weight 1, A will use up 80% of rendering time given to Mandelbulber, and B will use 20%. This is useful for when I want to render a flight and an image at the same time.
- Allow user to import a music file, and show the waveform along with keyframes. This is useful with varying framerate between keyframes (another feature that will be added). Might be useful to allow playing the music file as well.

I already know this problem. It happens not so often, and unfortunately is very difficult to reproduce (no any rule when it happens). Actually I have no clue why it happens, but it looks like something which blocks processing of Qt events (signal / slot mechanism).

I have a couple non-essential suggestions:
- Allow multiple Mandelbulber windows, and setting weight for each one. So if window A has weight 4 and window B has weight 1, A will use up 80% of rendering time given to Mandelbulber, and B will use 20%. This is useful for when I want to render a flight and an image at the same time.

There are system solutions for this. You can launch two Mandelbulber programs and set for them different system priorities. Under Windows you can change program priority in Task Manager. Under Linux for instant you can use 'nice' command to launch the program.
I would not implement this solution into the program, because handling of thread or program priorities is system dependent. Until the program is multi-platform I'm avoiding system dependent solutions.

- Allow user to import a music file, and show the waveform along with keyframes. This is useful with varying framerate between keyframes (another feature that will be added). Might be useful to allow playing the music file as well.
I have this solution in my head. I'm going to implement this when I will do 'animation by sound'. Then I can also do this what you mentioned, just to edit animation together with waveform view with variable frames/keyframe

New bug fix is released.

There was fixed bug reported by Starmute: image was black when intensity of any light source was zero. It affected rendering of keyframe animation where intensity of the lights was animated.

I've also had the redraw problem on occasion exactly as taurus described. Also the progress bar will disappear somewhat rarely. Both are fixed by restarting the program. I also feel it happens when I'm clicking too fast in the view and the system tries to redraw things to keep up.

Also, since my main schtick is putting music (my own) to fractal animations and the reverse, I'd love to see where I could more directly control one versus the other. Currently, I can use Virtual Dub to make the frames per second of a video file match the wave file, so the two will be the same length, and then manually change the FPS back to 30, and Virtual Dub will handle the rest (I believe by inserting frames (doubling or tripling them) and repeating or dropping them automatically). But I'd love, love, love to be able to change the frame rate between keyframes, and also sync the music more closely with the fractal animation. And use music as feeder data to directly manipulate parameters in real time!  grin

Great work making Mandelbulber better guys! (Although I've been using v 1.21 OpenCl lately almost exclusively because of the formulas mclarekin keeps porting over for me!)  A Beer Cup A Beer Cup A Beer Cup

The other is minimum iteration. Both of them are required to make flame fractal animations - by the way these look epic in 3D. Here is an example.
https://scontent.fakl1-1.fna.fbcdn.net/t31.0-8/12829115_10153585879029926_8868523938067441143_o.jpg

It's still possible to get this kind of flame fractals. You need to enable option "Stop at maximum iteration" on "Rendering engine" tab and set high value for "Maximum number of fractal iterations" (above 100). Then you need to set high intensity of glow effect.

Try this:
Code:
# Mandelbulber settings file

# only modified parameters

I'd put this into the feature request section, but this thread seems to get more notice. One request for the Netrender module: we can see the names, addresses, and number of cores of each networked computer, but the PC that is the host server (which also renders lines) is not shown. Could we add the cores and lines rendered by the host server machine as well? My host machine has a 16-core 5960X chip that eats through the lines twice as fast as my nearest i7, a Dell 4790. But the PC doing most of the work isn't shown because it's also hosting the party.

Also, my standard request (prayer) for OpenCL support!  wink Video cards get more and more powerful everyday, and the new 1080 is out. I know that might have to wait for a much later version. Cheers, and thanks, Krzysztof and all!

Thank you, upgrade again! I knew there was something I was missing. Back to flame fractals I go.
I'm still not sure how the colouring works with glow. Would it be possible to introduce more colours? A gradient for each colour?

On the subject of future (and past versions) support for OpenCL, I made an exciting discovery this morning. I've never been able to get Mandelbulber v 1.21 to use 2 video cards at the same time on the same computer, even if they were SLI'd together.

I accidentally loaded up 2 instances of Mandelbulber v.1.21 at a time--which I've done before, and quickly closed the other windows--but I never realized that the two instances could run just fine next to each other. I used to have 2 GeForce NVDIA MSI 980s installed, one in two different computers. I used to have both 980s in the same PC, and I SLI'd them together, but Mandelbulber would only ever use one at a time. I could switch from one to the other card, but never get them both to work at the same time on the same PC.

I finally started two instances of Mandelbulber Open CL and started one normally, but started the other one using the Device Index dropdown on the OpenCL tab and I changed the 2nd instance to 1 and kept the first at zero.

I loaded up the exact same file and keyframes and everything on the 2nd MDBR program and hit rend animation.

THE TWO VIDEO CARDS ARE RENDERING PERFECTLY NEXT TO EACH OTHER ON THE SAME PC!!!! (I'm pretty excited here, you might notice!)

I have the 1080 rendering away on a pc by itself, and then the PC with the 2 980s has two separate instances of Mandelbulber running as well.

That's a 980 and a 980 and a 1080 all making frames!!!!

That was probably the intent behind that dropdown select menu, but I've never seen any support whatsoever for any of the features on the OpenCL tab. Trial and error is the only way I've figured anything out so far, other than mclarekin's recent help. Just wanted to share that multi-GPU knowledge, unless I'm the only person in the world that used Mandelbulber v 1.21 that didn't already know that!

Cheers!
