Akeytsu 1.0.1 available

Hi guys,
Here's the new update! Enjoy ;-)

Version 1.0.1 [2017/11/15]
UI minor changes
It is not possible anymore to add an IK to joints constrained by a Reverse Foot
Changed Spinner Combo Move Rotate Mode default value to false

Main Bug Fixes
Fixed: Prevented OS(Windows) to consider Akeytsu as not responding (V1 black screen)
Fixed: ReverseFoot roll had issues in some cases of specific joint orientation
Fixed: When loading an akt with a Ref Pose, IK controllers were badly placed either in "Skin and Check" mode or in Animation mode (depending upon the active mode when the file was saved)
Fixed: Performances issue in "Skin and Check" mode, when character hierarchy was heavy (a lot of animation objects for instance)

Also several other crash and bug fixes...

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.
