Hytale 0.6.3: NPC Shadows Are Back, Transparent Textures Stop Casting, and Server Owners Have Nothing To Change

There is a third Update 6 hotfix. It is numbered 0.6.3, it carries the in-body date 31 August 2026, and it was appended to the same Update 6 hotfix post that already held 0.6.1 and 0.6.2. It is three bullets long. That is the whole build. But the sequence around it is worth reading, and there is one question underneath it that nobody has answered in public yet, so we will answer it in the first section rather than making you scroll. Start Here: You Do Not Need To Touch Your Server If you run a Hytale server, 0.6.3 asks nothing of you. Read the three fixes and notice what is absent. Nothing about config.json. Nothing about the protocol, packets, ports or NAT. Nothing about world data, chunk saving or migrations. Nothing about permissions, bans or the whitelist. Nothing about the Mod Browser. There is no setting to review, no file that moves, no plugin surface that changes shape, and no version gate that would stop a client on the previous build from connecting. This is a client-side build, and it is worth naming that plainly because the previous two were not. 0.6.2 was the one where a view radius above 32 in config.json stopped worlds and servers starting at all, which is about as far from optional as a hotfix gets. If that week trained you to treat every new number as a fire drill, this one is not that. What it does change is what your players see, and two of the three fixes are visible within a minute of logging in. So the practical move is the cheap one: tell them the build exists, and get on with your day. Two carry-overs from the stable release are still true and still yours, and neither is affected by 0.6.3. Your server and plugins must be built against the shipping shape of hytale/3, which our hytale/3 protocol breaking changes guide walks through, and your view radius is capped at 32 chunks, which our maxViewRadius config piece covers. If you did the work when Update 6 went stable, you are done. If you are still catching up, our full Update 6 stable patch notes with both same-day hotfixes is the article to work through, and the launch-day checklist is the running order. The Date Trap: This Is Not a 27 August Post Anyone citing this build is going to get the date wrong, so here is the shape of the trap. The hotfix post is a living page. Hytale appends new hotfix sections to it rather than publishing a fresh post for each one. The byline at the top still reads as posted on 27 August 2026, because that is when the page was first published with 0.6.1 and 0.6.2 on it. The 0.6.3 section further down carries its own version date of 31 August 2026. If you scrape the byline, you will date 0.6.3 to the 27th, merge it with the launch-day hotfixes, and lose the four-day gap that is the only interesting structural thing about it. The correct sequence is: 27 August 2026: Update 6 stable, plus 0.6.1 and 0.6.2, all three on the same day. 31 August 2026: 0.6.3, alone, four days later. The gap is the good news. Two hotfixes on release day is a scramble. One small hotfix four days later, containing no emergencies, is a release settling down. Rendering Fixes: NPCs Cast Shadows Again The headline fix is one sentence with two separate things inside it, and the second one is the one people will miss. Part one: this is a regression fix The wording is that NPCs cast shadows again. That word is doing real work. It means an earlier Update 6 build broke NPC shadows and shipped without them. There is a likely culprit, and it is sitting in the stable patch notes. Update 6 did not leave shadows alone. It carried a whole Lighting and Shadows section which, among other things, fixed shadows appearing missing or cut off at certain viewing distances and angles, stopped shadows leaking halfway through blocks, and corrected shadows from entities with block models that were rendering at half their intended size. That is a substantial rework of exactly the system that then lost NPC shadows. We cannot state cause from the notes alone, and Hytale has not said, but a regression landing inside a rework is the ordinary way this happens rather than a coincidence. What is clear either way is that it went out unflagged. It was not listed as a known issue in the stable patch notes, and neither same-day hotfix mentions shadows at all. It took until the third hotfix, four days later, to be named. That is an easy bug to live with and a hard one to report, which is probably why it took until the third hotfix to be named. A missing shadow does not crash anything, does not show an error, and does not stop you playing. It just makes creatures sit slightly wrong in the world, the way a badly composited object sits wrong in a photograph. Players notice the effect long before they can name the cause. The image at the top of this article is the useful mental model: a large creature standing in a lit woodland clearing is exactly the scene where a missing contact shadow reads as wrong. Part two: shadows now respect texture transparency The second half of the same bullet is not a regression fix at all. It is new behaviour: NPC shadows now follow the shape of the texture, so transparent parts of the texture no longer cast a shadow. Before this, the shadow came from the geometry. Hytale NPCs are built from boxes, and a lot of detail on those boxes is painted in with transparency rather than modelled: the gap between a cape and a leg, the notches in a leaf or a feather, the space between strands of hair, the cut-out silhouette of a wing. All of that is a solid rectangle as far as the geometry is concerned, so it produced a hard rectangular blob on the ground where the player expected a shaped outline. For anyone shipping custom NPC skins or creature mods, this is the entry in 0.6.3 that actually matters to you, and it cuts both ways: Alpha cut-outs finally read correctly. Capes, wings, foliage, antennae, hair and glass will now drop a shaped shadow instead of a box. If you avoided transparency because the shadow gave the trick away, that constraint is gone. Existing models will look different, not just better. Anything whose silhouette was quietly being propped up by a full-geometry shadow now loses that mass on the ground. A creature that felt weighty may read as lighter or thinner. It is worth an actual look, in sunlight. Shadow shape is only visible at certain angles and times of day. Load your NPC in an open, brightly lit area and walk a circle around it rather than judging it in a test room. None of this is a server-side change. Rendering happens on the player's machine, so this lands for every player who updates their client regardless of what build the server they are joining runs. UI and Quality of Life: Avatars, Again, and the Notification List Social avatars get further fixes 0.6.3 lists further fixes to social avatar profile loading and caching. The word to underline is further, because 0.6.2 four days earlier already claimed social avatars would load reliably for large friends lists instead of staying on the default portrait. So the honest reading is that the first fix did not fully land. Something was still failing, and the additional mention of caching alongside loading suggests where: an avatar that fetches correctly once but is stored or invalidated wrongly will look identical to an avatar that never fetched at all. You get the default portrait either way, and the second cause survives a fix aimed at the first. So if your friends list has been showing default portraits since Update 6 and 0.6.2 did not clear it, 0.6.3 is the build to try before you go looking for a local cause. If it is still wrong after this build, it is worth reporting, because two rounds of fixes have now been aimed at it. Opening the notification list is faster The third bullet is narrower than it first reads. It is not a general interface performance fix. The slowdown scaled with the number of pending friend requests, so the people who felt it were the ones with a backlog sitting in the list. That also explains why it would survive testing: an account with three pending requests opens the list instantly, and an account with a few hundred does not. If you run a server or a community, you are in the affected group almost by definition, because you are the person who accumulates requests. This one is likely to feel bigger for you than for your players. The Docs Are One Build Behind Worth knowing before you go looking something up. The version selector on docs.hytale.com currently reads Release 0.6.2 (current). The shipped client is 0.6.3. In practice this changes nothing, because 0.6.3 contains no API surface, no config keys and no asset schema, so there is nothing in it the documentation could be missing. But if you are reading the Java API or asset reference this week and you notice the version label, do not treat it as evidence that 0.6.3 is not real or that you are on the wrong build. The two simply move on different schedules, and the docs lag. Check which version a page is pinned to before trusting a signature on it, which was already good practice after the documentation split into release and pre-release sites at the stable launch. What Comes Next After Update 6: No Part 14, and No Update 7 Notes Because this hotfix is the first new Hytale content since the stable launch, it is worth stating the rest of the board as of 1 September 2026. There is no Update 6 Part 14. The rolling pre-release page's newest section is still Part 13 Hotfix 1, dated 22 August 2026, which we covered when it landed in our piece on the ICE networking rework. Part 13 was the last pre-release part, and Update 6 going stable is what closed that run. If somebody shows you a Part 14 changelog, it did not come from Hytale. There are no Update 7 pre-release notes. The pre-release page has not opened an Update 7 section, so there is no pre-release schedule to read for the rest of 2026, and the news index has no post dated later than 27 August other than the appended hotfix. There is no September news archive at all. There is no Update 7 release date and no Update 7 feature list. The only official mention of Update 7 anywhere is a single line in the Update 6 patch notes saying the team hopes to have a Double NAT solution in the Update 7 pre-releases. That is a hope attached to an unscheduled window, not a release date and not a commitment, and it tells you nothing about when Update 7 arrives or what else is in it. Anyone quoting you a date has invented one. For the longer arc, our piece on how many chapters Early Access is meant to cover is the honest version of the roadmap. That Double NAT line is worth holding on to precisely because it is the only forward-looking commitment of any kind on the record, and it is unchanged by this hotfix. If your traffic crosses two layers of address translation, you still cannot host for friends without an overlay, and 0.6.3 does not alter that. Be careful what you read on it, too: the pages currently ranking for Hytale NAT and connection problems are dated January 2026 and predate the Update 6 networking rework entirely, so their advice describes a system that no longer exists. FAQ What is the newest version of Hytale? 0.6.3, dated 31 August 2026. It is the third hotfix in the Update 6 line, after 0.6.1 and 0.6.2, which were both dated 27 August 2026 alongside the Update 6 stable release. Note that the official documentation site's version selector still reads Release 0.6.2 (current), which lags the shipped client. Do I need to update my Hytale server for 0.6.3? No. 0.6.3 is a client-side hotfix. It contains one rendering fix and two interface fixes, and nothing in it touches server configuration, the protocol, networking, world data, permissions or the Mod Browser. There is no setting to change and no file that moves. Your players will want the client build for the shadow and interface fixes, but your server needs nothing from you. The server-side work from Update 6 itself, chiefly rebuilding against hytale/3 and the 32 chunk view radius cap, still applies if you have not done it. What happened to NPC shadows in Hytale? An earlier Update 6 build broke them, and NPCs stopped casting shadows. 0.6.3 restores them. It also changes how they work: shadows now follow the shape of the texture, so transparent parts of an NPC texture no longer cast shadow geometry. Previously the shadow came from the box geometry, which meant alpha cut-outs like capes, wings, hair and foliage cast a solid rectangular shadow. Is there a Hytale Part 14? No. The pre-release page's newest section is still Update 6 Part 13 Hotfix 1 from 22 August 2026, and Update 6 has since gone stable, which closed that pre-release run. There is no Part 14 and no Update 7 pre-release notes. Any Part 14 changelog you are shown did not come from Hytale. Is there a Hytale Update 7 release date? No. The only official reference to Update 7 anywhere is a line in the Update 6 patch notes saying the team hopes to ship a Double NAT solution during the Update 7 pre-releases. That is a hope tied to an unscheduled window, not a date, and no Update 7 build number, feature list or timeline has been published. What is next after Update 6, and when do the Update 7 pre-releases start? Unknown. No Update 7 pre-release section has been opened on the pre-release page and no pre-release schedule has been published, so there is nothing to point at. The one thing tied to that window on the record is a Double NAT fix, which the team hopes to land during the Update 7 pre-releases. Everything else circulating about Update 7 features or timing is speculation. Why are my Hytale social avatars still not loading? Avatar loading has now been fixed twice. 0.6.2 addressed avatars staying on the default portrait for large friends lists, and 0.6.3 adds further fixes to profile loading and caching, which implies the first pass did not fully resolve it. If you have been seeing default portraits, update to 0.6.3 before troubleshooting anything locally. Why is my Hytale notification list slow to open? It scaled with the number of pending friend requests rather than being general interface lag, so accounts with a large backlog of requests felt it most. 0.6.3 makes opening the list faster in that situation. Where are the Hytale 0.6.3 patch notes? They are appended to the existing Update 6 hotfix post on hytale.com rather than published as a new article. That post is a living page, so its byline still shows 27 August 2026 from when it first went up with 0.6.1 and 0.6.2. The 0.6.3 section itself is dated 31 August 2026. What To Actually Do Players: take the build. Two of the three fixes are things you look at constantly, and the shadow change makes creatures sit properly in the world again. Server owners: nothing. Post a line in your Discord telling people the update exists and why they want it, then go back to whatever you were doing. If you are still working through the stable release, that is the job, not this. Mod and skin authors: this is your entry. Load your NPCs in open sunlight and walk around them. Anything using texture transparency now casts a different shadow than it did last week, which is an improvement in most cases and a silhouette change in all of them. Once you are on the current build, the point is finding somewhere worth playing on it. Browse the Hytale server list to find worlds running the latest release, or add your own so the players updating this week can find you.
