Unity3d巨大的内存使用纹理

Question

我有一个在iOS，Android和Windows Phone上运行的Unity3D内置的3D无尽亚军游戏。

它正常工作在Windows Phone上使用1014MB内存及以上，但在它一旦它开始崩溃（在文章底部看到从Visual Studio错误消息）。

看着探查器，我可以看到纹理的内存使用率非常高，知道我在Lumia 520上最多只能获得180MB RAM，例如，我可以从探查器看到纹理占用359MB ，甚至在第八个分辨率（下面的截图），他们仍然占用232MB！我已经经历了每一个纹理，使它尽可能小并且被压缩，我在这里做了些什么错事？我怎样才能更多地了解什么纹理是问题？

我通常在游戏中帮助帧速率开始预加载的所有程序级别的元素到内存中，一旦你正在运行，但我把这个完全关闭甚至当内存使用不受影响。

任何推向正确的方向将非常有帮助，谢谢！

我已经通过各种质地使它尽可能小和压缩，我可以走了，我做得真的错了吗？我怎样才能更多地了解什么纹理是问题？

呜呜..我不认为你正在做的事情是错误的。硬件上的内存限制是硬件问题，而非艺术家问题。然而，艺术家有限制，以应付为了能够应付硬件的限制，则：

1. 如果你这样做3D，您可以：确保你的模型具有为原料越少越好。您在模型上拥有的材料越多，此类模型最可能需要的纹理越多。如果您仍然需要，请确保其他模型尽可能共享相同的材料或共享一些网格组，以便您可以优化绘图调用。

2. 如果可以的话阿特拉斯纹理的使用也很好的帮助，因为它认为只有一种材料。那么它对内存的帮助不大，因为它仍然需要相同的内存。它只会帮助大多数的平局。

3. 像LearnCocos2D说，每色位是如果即使纹理是“小”尽量不使用例如32个纹理一个巨大的*。

4. 纹理分辨率或纹理是关键。如果您使用的是角色，并且您的角色在手机屏幕上很小，那么您应该使用非常小的纹理。例如，在某些游戏中，角色的高度为6英寸，而8英尺的墙壁被翻译为512x512px的贴图，用于表示壁部分中砖块的贴图，与角色形成鲜明对比。因此，举例来说，与这种角色形成对比的这种8英尺高的等高墙更高，已经开始浪费资源，并且视觉影响将最小化或根本不明显。定义3D手机游戏的纹理分辨率非常重要，以便更好地规划纹理资源。

   我建议您在本教程如果可以的话，它真的翔实的关于这个问题：http://www.digitaltutors.com/tutorial/1772-Creating-Professional-Studio-Game-Assets-for-Production-in-3ds-Max-and-Unity

5. 然后最后在你的情况下，由于其无限的，你真的需要使用启用/禁用，而不是破坏，并且确保相机剔除的距离正是您所需要的距离，否则您将无需加载大量玩家看不见的物体，这可能也是一个潮流......只是说。
