SideBySideの立体視画像を設定するとHMDで立体に見えるやつ
SideBySideStereoUnlit.shaderをUnityプロジェクトに入れるとシェーダー選択肢にUnlit/SideBySideStereoが追加されるので、
・ TextureにSteamVRスクリーンショットの横に並んでるやつを設定
・ VRCVideoSyncでYoutubeの3D動画を指定
とかすると立体に見えます。
変更箇所は、
> o.uv.x *= .5;
> if (unity_StereoEyeIndex != 0)
> {
> o.uv.x += .5;
> }
だけなのでUnlit以外が必要であれば各自改造願います。
