Update 1.1.0 Available!

Hi Akeytsu folks!
We hope you are well. While our team is focusing on V2 features (including tasty blendshapes :-)) we do not forget you for all that.
So here's Update 1.1.0 with the very nice "Hide Skinned Mesh Vertices" allowing, f.i, to hide the empty side of your model when working your half skin, to work your skin from the inside! Vertex lasso (and ability to select front only vertices) included too.
Enjoy ;-)

Version 1.1.0 [2018/05/21]
-Hide Skinned Mesh Vertices (new command in Skin Atelier)
-Vertex Lasso Selection (available on mouse middle button in Rigging Part)
Hand-draw a closed figure (one single "click'n'drag" or several "clicks'n'drag")
-Ability to select front vertex only (pick/rectangle/lasso)

-Unified selection “Full Paint mode“: now available for Painter action and selection, vertex rectangle selection and lasso selection
-Added/Modified cursor for vertices selection
-The "+" button on the numpad expands the selection in a classic way ; no more ring stuff
-Back of the scene characters are now lighted
-Curveboard: AutoFocus when the user starts a joint selection. Autofocus when the user hides or shows channel.
-LogProgressManager now also updates the Windows taskbar
-FBX: Optimized Uvs, Normals and Colors imports
-Added scale display (disabled) in Transform window in Default and Bind Pose
-Allowed MRS transformations on meshes in Animation mode
-Akeytsu installer now installs VC Redistributable vcredist2013 and vcredist2015
-Tweaked the red, green, blue and orange colors of Akeytsu UI

Crash Fixes
-Fixed crash when pasting (transform) without animation (button was not supposed to be active in this case)
-Fixed crash when reorienting with non controllers under joints
-Fixed crash when autosave folder was not writable

Bug Fixes
-FBX: Fixed materials export
-Fixed timeline bug (cursor frame index)
-Various bug fixes (DropList rendering, crash on IK deletion, Import freeze, curveboard crash, etc.)

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.
