I've an issue randomizing parameters in animation dock. The following randomizes In slight mode the included angles
  • not at all, which is not a problem or
  • somewhere around zero
especially gamma @ 32° is either untouched or destroyed to settings of +-2°. The same in medium and heavy randomization only stronger.
A quite special problem, but I've been waiting for this feature for quite some time, so I want to use. In this condition impossible.

It looks like a bug in randomization algorithm. I have to look into the code.

Bug fixed. I have mixed degrees with radians. The result after randomization was always in range of [-3.14, 3.14] degrees. Should be [-180, 180]. Tomorrow will be baken fresh win64 build.

Great, thanks! But theres no need for a hurry. Normally I can wait for the next stable one. Maybe I'll make an exception this time...

Thanks for the preferential treatment. You shouldn't have. But I'm glad to be able to try it soon, anyhow. Not so much for the refinement - csv random can be controlled more precisely - but for the general look.  :thumb_up:

I fixed this quickly, because the problem was well defined and reproducible. In such cases it is the best to fix problem immediately.

It is always a pleasure, especially when a function is implemented so exactly to my flavor.  ;)
