Author Topic: DE_factor not honored - problem seems to be in the keyframe files!  (Read 1036 times)

I have my DE_factor set to 0.035 in my settings file, but when I run mandelbulber it does not honor this setting and produces images with many black spots.  If I run it from the GUI, and hit the render button, I can watch the value slowly creep up from 0.035 to 1.0!

What am I doing wrong?  Here is my settings file:

Note that manually changed the DE_factor to 1.0 when I made my keyframes but have since raised it to 0.07 to render the entire movie.

OK!  I figured this out...  here's what happened:

1) I raised the DE_factor to 1.0 and dropped the resolution to 128x96 so I can quickly assemble my keyframes.  
2) I made 6 key frames
3) I adjusted the DE_factor to 0.035 and the resolution to 1280x720 and saved the config

Here is the problem.  Only the first keyframe has a line for DE_factor.  All subsequent keyframes lack this needed line and thus are defaulting to 1.0.  Here is a vimdiff to illustrate.  Is this behavior expected or a bug?

sorry to say that, but i don't even understand, what your problem is (maybe because i'm no native english speaker). so only a general note:

the de step is a float variable and like every other float variable in mandelbulber it will be animated. so if you change it manually, you'll have to change it in every key frame.
