<p>Epic Games has released the Unreal Engine 5.8 Preview via the Epic Games Launcher, GitHub, and Linux builds. It’s unstable by design - not recommended for converting active projects - but there’s a lot worth looking at.</p>
<h2>Mesh terrain</h2>
<p>The biggest structural change is an experimental mesh-based terrain system that replaces the traditional heightmap approach. Because it works with actual 3D meshes rather than a height grid, you can build overlapping geometry like caves and overhangs that were awkward or impossible before. It has native PCG integration built in.</p>
<h2>Procedural content generation</h2>
<p>The PCG framework now lets you make manual edits on top of procedural content, which closes a long-standing gap between procedural generation and hand-authored detail. The Procedural Vegetation Editor got a significant overhaul too, adding growth nodes, seed generation, foliage grafting, and Nanite-ready asset output.</p>
<h2>MetaHuman updates</h2>
<p>Several MetaHuman features landed together:</p>
<ul>
<li><strong>MetaHuman Collections and the Crowds plugin</strong> let you populate scenes with anywhere from tens to thousands of characters in real time</li>
<li><strong>Mesh to MetaHuman</strong> now converts any mesh - head and body - into a full MetaHuman, not just faces</li>
<li><strong>MetaHuman Animator</strong> adds Linux and macOS support</li>
<li><strong>MetaHuman Creator</strong> gets custom lighting scenes for previewing characters in context, plus unbaked texture editing before final bake</li>
</ul>
<h2>MegaLights</h2>
<p>MegaLights moves from experimental to production-ready, with improved performance on current-gen consoles. This one has been in preview for a while, so the graduation is notable.</p>
<h2>Animation and rigging</h2>
<p>Control Rig Physics moves to Beta. A new experimental Direct Mesh Controls (DMC) system is also introduced. Facial rigging tools have been expanded, and there are various other animation improvements throughout.</p>
<h2>Editor quality of life</h2>
<p>The editor widget now shows numerical movement and rotation indicators with visual delta feedback while you’re transforming objects - a small thing that makes a real difference when you’re trying to be precise.</p>
<h2>Unreal MCP plugin</h2>
<p>There’s an experimental plugin based on Anthropic’s Model Context Protocol that lets AI tools control the engine directly. It’s early and experimental, but the direction is clear.</p>
<h2>Other additions</h2>
<p>Rounding out the release: a new NPR (non-photorealistic rendering) solution, Dataflow and Chaos Physics improvements, mobile workflow enhancements, and various production rendering and virtual production updates.</p>
<p>Again - preview, unstable, not for production. But if you want to poke at mesh terrain or the crowd system, now’s the time.</p>
