光线(Ray)追踪是最新一代的渲染技术，可将实时图形推向真实感。它需要高端硬件才能使其正常工作，但如果您有 PC 来处理它，那么没有什么能比得上它的视觉风格了。
即使以复古风格的块状 3D 世界而闻名的Minecraft也未能逃脱光线追踪的光芒。(Minecraft)默认情况下未启用它，但如果您拥有合适的硬件，您将迎来一段神奇的时光。
光线追踪(Ray Tracing Do)在Minecraft中有何作用？
首先，游戏中通常所说的实时光线追踪是一种更高级的方法，称为路径追踪。两者之间的总体思路是相同的，但路径跟踪中使用的数学可以得到更好的最终图像。在本文中，我们将坚持使用“光线追踪”，但值得了解“路径追踪”这个术语，因为它在现代图形讨论中反复出现。
要深入了解这项技术，请查看什么是光线追踪？(What Is Ray Tracing?)&什么是路径追踪和光线追踪？(What are Path Tracing and Ray Tracing?)
在Minecraft中，光线追踪使Minecraft更加逼真。模拟光(Light)以使其在现实生活中发挥作用。Minecraft中物体的纹理也被替换为启用了光线追踪模式的PBR （基于物理的渲染）材质。(PBR)也就是说，木材具有木材的光学特性。金属按其应有的方式发挥作用，依此类推。
结果是一个带有反射、阴影和照明的Minecraft世界，看起来更像是Minecraft的真实世界立体模型，而不是视频游戏。必须亲眼所见才能相信，所以请在这些屏幕截图上大饱眼福。
太棒了(Amazing)，对吧？如果您渴望亲自进入光线追踪的Minecraft世界，让我们首先检查您的系统是否满足最低要求。
Minecraft 光线追踪要求
要在Minecraft(Minecraft)中使用光线追踪模式，您需要满足以下要求：
- Windows 10 或 11 64 位
- Nvidia RTX GPU(Nvidia RTX GPUs)或Radeon RX 6000或更好
- Intel Core i5 同等或更好
- 8 GB RAM（更推荐）
在撰写本文时，只有Minecraft的(Minecraft)基岩版(Bedrock Edition)支持光线追踪。此版本也称为Windows 10版(Edition)，但在Windows 11上也能正常工作。仍然非常流行的Java版本的Minecraft不支持光线追踪。
虽然Radeon RX 6000 系列卡支持硬件加速光线追踪，但它们没有像 Nvidia 的RTX卡那样的专用硬件。如果你有一个低端的RX 6000 GPU，你可能会在Minecraft中遇到光线追踪的一些性能问题，尤其是在你提高细节的时候。
您还应该注意，Minecraft 的基岩版(Minecraft)可(Bedrock Edition)通过PC 版 Xbox Game Pass(Xbox Game Pass for PC)或Game Pass Ultimate获得。如果您是首次订阅者，通常可以在第一个月花一美元试用它，看看它是否适合您。如果您过去购买了Java 版(Java Edition)，则无需购买基岩版(Bedrock Edition)，除非您不想通过Game Pass玩游戏。
如何在Minecraft中打开光线追踪(Ray Tracing)
首先要做的是将您的GPU驱动程序更新到最新版本。如果有任何待处理的更新，更新Windows也是一个好主意。如果您是Game Pass 订阅者(Game Pass subscriber)，请在Microsoft Store 应用中(Microsoft Store App)购买 Minecraft 基岩版(Purchase Minecraft Bedrock Edition)或从Xbox应用安装。
启动游戏后，您必须使用您的Microsoft 帐户登录(Microsoft Account)。如果您已经通过Windows登录，这应该会自动发生。
- 如果您打开设置(Settings)>视频(Video)并向下滚动设置列表，您将在菜单中看到带有切换开关的光线追踪。(Ray Tracing)但是，此选项显示为灰色，您无法将其打开。
- 要启用它，您需要一个兼容光线追踪的资源包，其中包含合适类型的纹理和照明设置。所以回到主菜单并打开Marketplace。
- 在市场上，您可以找到付费和免费内容。您还会发现这两种光线追踪包。选择放大镜(magnifying glass)以打开搜索栏，然后在此处输入“光线追踪”输入搜索(Enter search here)。
- 结果的顶部应该是由Nvidia创建的几个包，它制造RTX GPU(RTX GPUs)。您会注意到缩略图带有RTX 徽标(RTX logo)，但第三方包可能没有。
- 对于本教程，我们将使用Imagination Island RTX。选择显示“免费(Free)”的按钮来领取礼包。然后等待购买完成。
- 接下来选择下载(Download)。
- 在下一个窗口中再次选择下载以确认。(Download)
- 等待(Wait)下载完成。发生这种情况时，您不能做任何其他事情。
- 下载完成后，选择Create this World!然后，如果要进行在线会话，请选择Create或Create on Realms Server 。
- 等待(Wait)资源包加载。如果您收到有关在线游戏未评级的警告，请选中不再显示此屏幕(Do not show this screen again)，然后选择继续(Proceed)。
等待(Wait)世界生成过程完成，您应该会在游戏中生成。
如果游戏仍然看起来像普通的Minecraft，请返回主菜单。然后选择设置(Settings)>视频(Video)并将光线追踪开关切换(Ray Tracing switch)到打开位置。重新渲染游戏世界时，您的屏幕可能会短暂闪烁。
事情现在应该看起来大不相同。欢迎来到光线追踪的 Minecraft 世界！
如果你想回到光线追踪的世界，你所要做的就是从主菜单中选择新游戏(New Game)，然后从列表中选择一个RTX世界。
调整光线追踪设置
与Cyberpunk 2077等游戏不同， (Cyberpunk 2077)Minecraft中的光线追踪设置没有太多可以调整的地方。您唯一可以控制的是光线追踪渲染距离(Ray Tracing Render Distance)和放大(Upscaling)。
顾名思义，渲染距离决定了光线被追踪到的距离。超出您设置的渲染距离，不会应用光线追踪。因此，远处的物体可能不会在靠近您的闪亮表面上反射。此设置越高，图形看起来就越壮观，尤其是在阳光照射的户外区域。
八个“块”距离是默认设置和最小值。我们建议一次将其提高一个档次，直到游戏不再可玩或变得不稳定。不用担心。你不能破坏任何东西。可能发生的最糟糕的情况是游戏崩溃，您将知道您可以将系统推到多远。
放大只是意味着游戏在屏幕的原始分辨率以下渲染，然后放大。这是提高性能的好方法，而且Minecraft因其厚实的特性而可以很好地扩展，因此如果帧速率较低，请打开此选项。
(Ray Tracing)Xbox Series X上的Minecraft光线追踪
尽管微软已经展示了在Xbox Series X上运行的 Minecraft 光线追踪版本，(demonstrated a ray-traced version of Minecraft)但在我们撰写本文时，没有迹象表明这将成为官方功能。如果你想要光线追踪的Minecraft，唯一的地方就是使用基岩版(Bedrock Edition)的 PC 。
没有光线追踪 GPU(Ray-Tracing GPU)吗？尝试替代着色器(Try Alternative Shaders)和OptiFine
不是每个人都能购买最新的 GPU，或者您可能更喜欢Java 版(Java Edition)的Minecraft，它没有微交易和 Windows 10 和 11 锁定。
虽然您无法获得真正的光线追踪，但您可以下载许多替代着色器包来显着改变游戏的外观。
“着色器”是指像素着色器，它是一种特殊的图形程序，可帮助确定游戏中每个像素应具有的确切颜色和亮度值。有着色器可以让事物看起来很潮湿，也有着色器可以让事物看起来很亮或在阴影中。您想在计算机屏幕上实现的任何内容都有着色器。
虽然传统的基于着色器的图形看起来不如光线追踪，但您可以非常接近！有很多选项，这不是Minecraft中替代着色器的指南。但是，一个很好的起点是使用备用着色器和Optifine。YouTuber Daniel Plays有一个很好的教程(excellent tutorial)，引导玩家完成这个适度的技术过程。
How to Turn on Ray Tracing in Minecraft
Ray tracing is the latest generation of rendering technologу to push real-time graphics closer to photorealism. It takes high-end hardware to make it work well, but if you’ve got the PC to handle it, there’s nothіng else like its visual flair.
Even Minecraft, known for its retro-style blocky 3D worlds, has not escaped the ray tracing glow-up. It’s not enabled by default, but you’re in for a magical time if you have the right hardware.
What Does Ray Tracing Do in Minecraft?
First, what’s generally referred to as real-time ray tracing in games is a more advanced approach known as path tracing. The general idea between the two is the same, but the math used in path tracing makes for a better final image. For this article, we’re just going to stick to “ray tracing,” but it’s worth knowing the term “path tracing” because it comes up repeatedly in modern graphics discussions.
For a deep dive into this technology, check out What Is Ray Tracing? & What are Path Tracing and Ray Tracing?
In Minecraft, ray tracing makes Minecraft more photorealistic. Light is simulated to act as it does in real life. The textures of objects in Minecraft have also been replaced with PBR (Physically-based rendering) materials with ray tracing mode on. In other words, wood has the optical characteristics of wood. Metal acts as it should, and so on.
The result is a Minecraft world with reflections, shadows, and lighting that looks more like a real-world diorama of Minecraft than a video game. It must be seen to be believed, so feast your eyes on these screenshots.
Amazing, right? If you’re keen to enter the world of ray-traced Minecraft for yourself, let’s start by checking if your system meets the minimum requirements.
Minecraft Ray Tracing Requirements
To use the ray-tracing mode in Minecraft, you need to meet the following requirements:
- Windows 10 or 11 64-bit
- Nvidia RTX GPUs or Radeon RX 6000 or better
- Intel Core i5 equivalent or better
- 8 GB RAM (more recommended)
Only the Bedrock Edition of Minecraft supports ray tracing at the time of writing. This version is also known as the Windows 10 Edition, but it works just as well on Windows 11. The Java version of Minecraft, which is still immensely popular, doesn’t support ray tracing.
While Radeon RX 6000-series cards support hardware-accelerated ray-tracing, they don’t have dedicated hardware like Nvidia’s RTX cards. If you have a low-end RX 6000 GPU, you may have some performance issues with ray tracing in Minecraft, especially if you crank up the detail.
You should also note that the Bedrock Edition of Minecraft is available through Xbox Game Pass for PC or Game Pass Ultimate. If you’re a first-time subscriber, you can usually get the first month for a dollar to try it out and see if it works for you. There’s no need to purchase the Bedrock Edition if you have bought the Java Edition in the past unless you don’t want to play through Game Pass.
How to Turn on Ray Tracing in Minecraft
The first thing to do is update your GPU drivers to the latest version. It’s also a good idea to update Windows if there are any pending updates. Purchase Minecraft Bedrock Edition in the Microsoft Store App or install it from the Xbox app if you’re a Game Pass subscriber.
Once you launch the game, you’ll have to sign in with your Microsoft Account. If you’re already signed in through Windows, this should happen automatically.
- If you open Settings > Video and scroll down the list of settings, you’ll see Ray Tracing with a toggle switch in the menu. However, this option is grayed out, and you can’t turn it on.
- To enable it, you’ll need a ray-tracing compatible resource pack containing suitable types of textures and lighting settings. So head back to the main menu and open Marketplace.
- In the marketplace, you can find both paid and free content. You’ll find both kinds of ray-tracing packs as well. Select the magnifying glass to open the search bar and type “ray tracing” where it says Enter search here.
- At the top of the results should be several packs created by Nvidia, which makes RTX GPUs. You’ll notice that the thumbnails have the RTX logo, although third-party packs may not.
- For this tutorial, we’re going with Imagination Island RTX. Select the button that says Free to claim the pack. Then wait for the purchase to complete.
- Next select Download.
- Select Download again in the next window to confirm.
- Wait for the download to complete. You can’t do anything else while this happens.
- After the download completes, select Create this World! Then, choose Create or Create on Realms Server if you want to make an online session.
- Wait for the resource pack to load. If you get a warning about online play not being rated, check Do not show this screen again and then select Proceed.
Wait for the world generation process to complete, and you should be spawned in the game.
If the game still looks like regular Minecraft, go back to the main menu. Then select Settings > Video and toggle the Ray Tracing switch to the on position. Your screen might flash briefly as the game world is re-rendered.
Things should now look dramatically different. Welcome to the world of ray-traced Minecraft!
If you want to return to a ray-traced world, all you have to do is select New Game from the main menu and then choose an RTX world from the list.
Adjusting Ray Tracing Settings
Unlike in games such as Cyberpunk 2077, there’s not much you can adjust to ray tracing settings in Minecraft. The only things you have control over are Ray Tracing Render Distance and Upscaling.
As the name suggests, render distance determines how far into the distance rays are traced. Beyond the render distance you set, ray tracing isn’t applied. So distant objects may not be reflected in shiny surfaces close to you. The higher this setting, the more spectacular the graphics will look, especially in outdoor areas lit by the sun.
Eight “chunks” of distance are the default setting and the minimum. We suggest pushing this up one notch at a time until the game is no longer playable or becomes unstable. Don’t worry. You can’t break anything. The worst that can happen is that the game crashes, and you’ll know how far you can push your system.
Upscaling simply means that the game is rendered below your screen’s native resolution and then scaled up. This is a great way to improve performance, and Minecraft scales well thanks to its chunky nature, so toggle this on if the frame rate is low.
Ray Tracing for Minecraft on Xbox Series X
Although Microsoft has demonstrated a ray-traced version of Minecraft running on the Xbox Series X, as we write this, there is no indication that this will become an official feature. If you want ray-traced Minecraft, the only place is a PC using the Bedrock Edition.
No Ray-Tracing GPU? Try Alternative Shaders and OptiFine
Not everyone is in the position to buy the latest GPU, or perhaps you prefer the Java Edition of Minecraft, which lacks the microtransactions and Windows 10 and 11 lock-ins.
While you can’t get true ray tracing, there are many alternative shader packs you can download to change the game’s look dramatically.
“Shaders” refer to pixel shaders, which are special graphics programs that help determine the exact color and brightness value that every pixel in the game should have. There are shaders to make things look wet and shaders to make things look lit or in shadow. There are shaders for anything you want to achieve on a computer screen.
While traditional shader-based graphics don’t look as good as ray tracing, you can get pretty close! There are many options, and this isn’t a guide for alternative shaders in Minecraft. However, an excellent place to start is with alternate shaders and Optifine. YouTuber Daniel Plays has an excellent tutorial that walks players through this moderately technical process.
