1. 우선 새로 보여질 카메라를 하나 만든다.

2. 새 카메라의 Depth는 메인 카메라의 Depth보다 낮아야 된다.(같거나 높으면 메인 창에서도 새 카메라를 사용해버림)

3. 아래에서 m_strQuaterViewerName 은 카메라 오브젝트 이름이다. 임의로 집어넣게 만들어 놨음..

4. QuarterViewer.cs 스크립트는 Project 탭의 Editor 폴더 하위에 들어가야 한다.(에디트 시 사용될 스크립트라서..)

P.s. 예제에서는 RenderTextureFormat.ARGB32를 썼는데 Depth 문제가 있어서 RenderTextureFormat.Depth 로 고쳤다.

Well, just take the example from the GUI slider reference and from Animation.Sample and you're done.

private var hSliderValue : float = 0.0;
private var myAnimation : AnimationState;
 
function Start(){
    myAnimation = animation["MyClip"];
}
 
function LateUpdate() {
    myAnimation.time = hSliderValue;
    myAnimation.enabled = true;
 
    animation.Sample();
    myAnimation.enabled = false;
}
 
function OnGUI() {
    hSliderValue = GUILayout.HorizontalSlider (hSliderValue, 0.0, myAnimation.length,GUILayout.Width(100.0f));
}

Answering to my own thread here.

It seems like the MeshMerger script from the wiki itself was causing this trouble. On fourth thought and investigation it seems like copying of triangles and vertices is kind of buggy in the script, so finally I also saw some lonesome vertices flowing in the world after combining. Therefore it might not be the best idea to use that script at all.

Nevertheless, the CombineChildren script from the Standard Assets turned out to be a much better basis to work with. I've rewritten parts of it now to suit my needs, which basically is generating the combined static geometry in the editor and being able to generate lightmaps for this as well. Works like a charm!

I've seen this topic multiple times in the community without a real solution, so it might be a good idea to have a script ready for this. No big adjustment, but I hope it helps some people out there. Here it is, use it as you wish.

CombineChildrenAdvanced.cs
Usage: Place this anywhere in your project and attach it to the parent gameObject containing the other meshes to be combined.
Basically it delivers the very same feature as the standard CombineChildren script, yet it needs to be executed in the editor.
By default it'll automatically generate the lightmapping UVs for the combined geometry. If you don't want this to happen, either use the CombineChildren.cs from the Standard Assets, or uncheck the corresponding checkbox.
If you want to split geometry up again, just use the corresponding button. It'll reset everything accordingly.

using UnityEngine;
using System.Collections;
/*
Attach this script as a parent to some game objects. Then by using the corresponding controls you may generate combined meshes (with lightmapping UVs).
This is useful as a performance optimization since it is faster to render one big mesh than many small meshes. See the docs on graphics performance optimization for more info.
 
Different materials will cause multiple meshes to be created, thus it is useful to share as many textures/material as you can.
NOTE: Using multiple materials may break things due to lightmapping generation. So lightmapping UVs as well as splitting the combined geometry is not supported.
Workaround: Create hierarchies in which the children only have exactly one material.

Camera.WorldPositionToViewportPoint() 라는 함수를 사용합니다.

오늘 레퍼런스[2016-04-01] 확인해보니 유니티가 업데이트 되면서 함수명이 조금 바꼈네요.

Camera.WorldToViewportPoint() 입니다.

리턴되는 Vector3의 x, y 좌표가 [0~1] 범위 안에 있고, z좌표가 0보다 크면 보이는 겁니다. ^^

요즘 제작중인 RPG 게임 GUI 에서 영웅 생성을 위해 캐릭터를 선택하는 UI 를 커버플로우(Cover Flow)로 구성하게 되어 NGUI 를 조금 응용해서 심플하게 구성해봤습니다. 아래 동영상과 유니티 데모를 보시면 대략 어떤 것인지 아실 수 있을 것이며 혹시나 구현 방법에 대해 관심 있는 분들은 첨부 파일을 받아서 패키지 임포트로 유니티에서 가져가 내용을 살펴 보시면 되겠습니다. NGUI 외에도 트위닝 모션을 위해 HOTween 플러그인을 사용하는 코드가 있으나 수정해서 쓰셔도 되겠습니다. 그리고 데모에 보이는 캐릭터 디자인 소스는 에셋 스토어에서 구입한 것이네요. NGUI 플러그인에 이런 기능도 포함되면 좋을 것 같은데 안된다면 아쉽지만 저처럼 이렇게 구현해야 되겠지요.^^ 여러분은 지금 어떤 기능들을 추가해보고 있나요?
