1) Stride Bone For walkcycles, you could already set an NLA strip to cycle over a path based on a preset distance value. This cycling happens based on a linear interpolation, with constant speed. Not all cycles have a constant speed however, like hopping or jumping. To ensure a perfect slipping-less foot contact, you now can set a Bone in an Armature to define the stride. This "Stride Bone" then becomes a sort-of ruler, a conveyor belt, on which the character walks. When using the NLA "Use Path" option, it then tries to keep the Stride Bone entirely motionless on the path, by cancelling out its motion (for the entire Armature). This means that the animation keys for a Stride Bone have to be exactly negative of the desired path. Only, at choice, the X,Y or Z Ipo curve is used for this stride. Examples: http://www.blender.org/bf/0001_0040.avi The top armature shows the actual Action, the bottom armature has been parented to a Path, using the Stride Bone feature. http://www.blender.org/bf/0001_0080.avi Here the Stride Bone has a number of children, creating a ruler to be used as reference while animating. Test .blend: http://www.blender.org/bf/motionblender1.blend Notes: - Note that action keys for Bones work local, based on the Bone's orientation as set in EditMode. Therefore, an Y translation always goes in the Bone's direction. - To be able to get a "solvable" stride, the animation curve has to be inverse evaluated, using a Newton Raphson root solver. That means you can only create stride curves that keep moving forward, and cannot return halfway. - Set the Stride Bone in the Editing Buttons, Bone Panel. You can set change the name or set the axis in the NLA Window, Strip Properties Panel. - Files in this commit will move to the blender.org release section. 2) Armature Ghosting In EditButtons, Armature Panel, you can set an armature to draw ghosts. The number value denotes the amount of frames that have to be drawn extra (for the active action!) around the current frame. Ghosts only evaluate its own Pose, executing it's Actions, Constraints and IK. No external dependencies are re-evaluated for it. 3) NLA/Action time control If you click in the NLA window on the action (linked to Object), it makes sure the Timing as drawn in the Action editor is not corrected for NLA. If you also set the Object to "Action", this timing will be executed on the Object as well (not NLA time). (It's a bit confusing... will make a good doc & maybe review UI!) |

Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/docs/get_involved.html Community: http://www.blender3d.org/Community/ Main blender development site: http://www.blender.org/ The Blender project homepage: http://projects.blender.org/projects/bf-blender/ Documentation: http://www.blender.org/modules.php?op=modload&name=documentation&file=index Bug tracker: http://projects.blender.org/tracker/?atid=125&group_id=9&func=browse Feature request tracker: http://projects.blender.org/tracker/?atid=128&group_id=9&func=browse
