Unity3d巨大的內存使用紋理

Question

我有一個在iOS，Android和Windows Phone上運行的Unity3D內置的3D無盡亞軍遊戲。

它正常工作在Windows Phone上使用1014MB內存及以上，但在它一旦它開始崩潰（在文章底部看到從Visual Studio錯誤消息）。

看着探查器，我可以看到紋理的內存使用率非常高，知道我在Lumia 520上最多隻能獲得180MB RAM，例如，我可以從探查器看到紋理佔用359MB ，甚至在第八個分辨率（下面的截圖），他們仍然佔用232MB！我已經經歷了每一個紋理，使它儘可能小並且被壓縮，我在這裏做了些什麼錯事？我怎樣才能更多地瞭解什麼紋理是問題？

我通常在遊戲中幫助幀速率開始預加載的所有程序級別的元素到內存中，一旦你正在運行，但我把這個完全關閉甚至當內存使用不受影響。

任何推向正確的方向將非常有幫助，謝謝！

我已經通過各種質地使它儘可能小和壓縮，我可以走了，我做得真的錯了嗎？我怎樣才能更多地瞭解什麼紋理是問題？

嗚嗚..我不認爲你正在做的事情是錯誤的。硬件上的內存限制是硬件問題，而非藝術家問題。然而，藝術家有限制，以應付爲了能夠應付硬件的限制，則：

1. 如果你這樣做3D，您可以：確保你的模型具有爲原料越少越好。您在模型上擁有的材料越多，此類模型最可能需要的紋理越多。如果您仍然需要，請確保其他模型儘可能共享相同的材料或共享一些網格組，以便您可以優化繪圖調用。

2. 如果可以的話阿特拉斯紋理的使用也很好的幫助，因爲它認爲只有一種材料。那麼它對內存的幫助不大，因爲它仍然需要相同的內存。它只會幫助大多數的平局。

3. 像LearnCocos2D說，每色位是如果即使紋理是「小」儘量不使用例如32個紋理一個巨大的*。

4. 紋理分辨率或紋理是關鍵。如果您使用的是角色，並且您的角色在手機屏幕上很小，那麼您應該使用非常小的紋理。例如，在某些遊戲中，角色的高度爲6英寸，而8英尺的牆壁被翻譯爲512x512px的貼圖，用於表示壁部分中磚塊的貼圖，與角色形成鮮明對比。因此，舉例來說，與這種角色形成對比的這種8英尺高的等高牆更高，已經開始浪費資源，並且視覺影響將最小化或根本不明顯。定義3D手機遊戲的紋理分辨率非常重要，以便更好地規劃紋理資源。

   我建議您在本教程如果可以的話，它真的翔實的關於這個問題：http://www.digitaltutors.com/tutorial/1772-Creating-Professional-Studio-Game-Assets-for-Production-in-3ds-Max-and-Unity

5. 然後最後在你的情況下，由於其無限的，你真的需要使用啓用/禁用，而不是破壞，並且確保相機剔除的距離正是您所需要的距離，否則您將無需加載大量玩家看不見的物體，這可能也是一個潮流......只是說。
