For using the MMD Model, Sincere Thanks to the Designer and Company listed.

3DXchange5 Pipelineを使うとMMDキャラクターをiClone非標準キャラクター化してから、キャラクターの形状と内蔵モーションをFBX形式でUnityに渡し、ゲーム環境内で使用できるようになります。

今回のテストではMMDモデルとして「結月ゆかり」を新たに使わせて頂き、Unity（フリー版）内でマテリアルを修正したり、カスタムモーションを再生するための方法について試行してみました。　

MMD Models have been defined in 3DXchange as iClone Non-Standard Model and so they can be used in Unity Environment.

This Test is made for MMD 3D Models with Custom motions to be exported to Unity by using 3DXchange5 Pipeline by FBX format.

According to Reallusion video articles, not only Standard iClone Models, but Non-Standard Models can be imported to Unity with motions as Avatars and no further modifications are required for applying the imported motion in Unity.

Not only Custom motions applied to iClone Standard Model by Persona in iClone are imported to Unity, but other Custom iMotions listed in Motion Libraly of 3DXchange5 for Non-Standard Models can also be imported.

This is a very basic study for MMD Models using in Unity.
Interactive control in Unity will be tested in the future report.
This is also my personal interest and no business issues are involved.

The test step is as follows:

	1.	Prepare MMD Non-Standard Model with iMotions.
	2.	Export Geometry only by Export FBX advanced settings preset for Unity.
	3.	Export Each iMotions without Geometry in the same way.
	4.	Prepare a Stage for the use in Unity.
	5.	Set up Unity environment and get to know the Unity interface. Utilize the Project, Hierarchy, Inspector & Animation view panel.
	6.	Basic MMD Model set-up operation in Unity.
	7.	Applying imported Animation to the MMD model.
	8.	Learn how to change imported motions.
	9.	Playing imported motions on two Models.
	10.	More test for MMD Model and Custom Motion play.
