Akeytsu 1.2.0 available

Hi Akeytsu friends,

We hope you are all fine (surely preparing Halloween ;-)).
Here in Lyon, our team stays focused on V2 features. However we don't forget you so please find a new version of Akeytsu.
Enjoy... and happy Halloween ;-)

Version 1.2.0
- IK and Reverse Foot rework
---- More stable
---- More accurate
---- Transform actions more accurate
---- Backward compatibility (ability to reload old files containing RF)
- In BindPose/RefPose, when you move an ancestor of an IK/RF string, IK/RF controller is now moved relatively
- Meshes are now optimized at import and file loading
- Tree: When a character has no more joint, his meshes are unskinned
- Skin Atelier: Removed 0. step in weight spinner, restored weight edition with weight buttons
- Added selection "Descendants Only" on Middle Mouse Button click (useful to quickly select all fingers!)
- Added display preferences, added setting "Show Decorators affects all views"
- Added shortcut to Show/Hide selected objects (press H)
- Added 64 bits PNG texture support by converting to 32 bits
- Rounded values at FBX export
- Added version number under top Main menu logo

Crash Fixes
- Fixed a crash when a mesh is imported without vertex
- Fixed a crash with a Dual screen config, when rectangle selection bottom right corner was outside the main screen

Bug Fixes
- Curveboard: The curves are now also auto-focused if the user selects an IK/RF (not just a joint)
- Fixed unique name for characters
- Fixed UVs, normals, colors export
- Fixed mirroring functions to use the hardcoded plan Y-Z (and not depend anymore on Aim and Second axes settings from Skeleton window)
- Smooth skin bug fixed: Weights were set to infinite values in some cases. Notably when the smoothing part was too strong
- Fixed: User could not use MirrorSkin action anymore when the character did not have mesh

About This Software

3D animation software did not evolve that much during the last 20 years... until Akeytsu, a brand new 3D software dedicated solely to animation and rigging developed by nukeygara came out on the market. Disruptive, fast and easy Akeytsu is an intuitive software for Indie game creators.

akeytsu’s motto: designed by/for animators… designed to be easy and fun

Even if 3D animation is intrinsically an artistic endeavour, it unfortunately has been transformed into a high-level technical activity by most of the software in the market. These programs are overly complicated with an endless learning curve.

With its artistic-oriented approach and its unique interface, akeytsu breaks up classic standards of current broad-based solutions by providing a new "animation & rigging only" workflow built on simplicity, rapidity, velocity and ergonomics.

The result is an uncompromising design where each and every feature was thought for animators. And not only for professional animators, akeytsu is so easy that now anyone can create quick posings and have fun by discovering 3D animation.

game industry as target

At nukeygara we made a choice : providing 3D animation access to the huge community of game/indie game developers. Most of them stick with 2D due to 3D issues: overly technical, skills lacking in teams, long learning curves, etc. This situation has to change ! The first akeytsu version and its solid FBX format support in/out fits perfectly with game studios needs and especially Unity 3D or Unreal Engine workflows.
