Welcome to Fractal Forums

Hi -
I just started using Mandelbulber this week (v1.12 for Mac) and I'm having this problem: I've rendered a series of keyframes for animation (about 12) and to do a test animation, I had the detail, DE step and smoothness all set to 1.  I'd now like to do a hi-res animation, render, so I set the detail and smoothness to 2 and the DE Step down to 0.3, but when I select another keyframe it resets my detail / smoothness / DE Step parameters. 

I thought maybe these values are stored in the keyframes.fract files so I looked in them but could not find a parameter that matched those settings. 

Where would I be able to make the parameter change stick without having to regenerate all of the keyframes?

Thanks.

At first glance, the answer is simple:
Those parameters are animated just like almost any other float parameter in mandelbulber. So you'll have to change in every single keyframe and save back...

A little hint from me. Such dull repeating changes are easiely made with a text editor or a batch replacement tool ("far" works on windows). Keyframe-Files - like every fract file - are saved in clear language. ;D 

just found this in related topics. Somewhat old, but maybe useful for mac as well.

Thanks taurus66 - I opened the keyframe.fract and settings files in a text editor and I've been able to find my way around them pretty easily - and in some cases, I can see where if I set the detail or smoothness differently between keyframes, the values are interpolated across frames as the animation rendering moves from one to the next.

Problem is, I can't find anything that matches "smooth" or "detail" when searching the files.

If I stop rendering, and change these values, say from "1" to "2", then when I start rendering animations from keyframes again, the value gets reset to "1".

Could these keys be stored under a different name?  

smoothness is smoothness in fract file, except when set to 1. Then it doesn't appear, because it's the default value.
"detail level" is "quality" in fract file, except when set to 1...

You need to save back to keyframe file after changing. I do this by "save settings", just like an ordinary fractal parameter file. should also be possible with "record" in timeline, but I never did, so no advise from me.

I just loaded all 40 of my keyframes into Sublime text and did some global search and replace and saw that yes, the "smoothness" parameter only shows up in a few of them when I change the value away from 1. 

Mystery solved.  Thanks.
