Unturned 3.17.10.0 Update Notes

Edit regarding unable to open Steam overlay

The improved BattlEye security this update has made it harder for cheaters to break into the game, but it’s also had the unexpected side effect of blocking the Steam overlay due to the order in which Unity starts up the game. Unfortunately this means it can’t be fixed from within Unturned itself in a patch, but we’ve come up with a few ideas and hope to have it working properly again for the next update.

Edit: This has been fixed in the 3.17.10.1 patch.

Festive Update

Russia has frozen over for the winter! It’s cold enough that a swim is an easy way to freeze yourself, but on land you should be fine - aside from the restricted visibility! The Festive Gift Present is also dropping again with some new skins and elf outfit, although at a 50% chance rather than the usual 100% because the event is longer than previously. A few curated workshop items were accepted this week, but there will be another wave next week so get yours in as soon as possible if you’re working on a holiday themed item!

Trees

TL;DR: Try out “New Trees - Blending Off” with wind quality “Low” and see if your computer can handle it!

You might remember a bit over a year ago I experimented with some alternate appearances for the trees which got everyone excited, but this week I actually upgraded every single tree and got them into the game! There are two graphics options related to these: tree quality and wind quality.

Legacy tree quality will use the original models. Blending off uses the new models, but with sharp transitions between LODs, whereas blending on smoothly grows out tree details as you get closer at a significant performance cost. Changing tree quality requires a game restart to take effect. Using the old tree models will still use the new tree hitboxes, however.

Wind quality is the bigger peformance drain. Low is equivelant to the old windy foliage setting, but won’t apply any wind to the new tree models. Ultra looks really fantastic especially in very windy conditions like in a storm or next to a helicopter hovering - the trunk bends to the wind, branches swaying slightly and leaves rustling.

Grass/Foliage

TL;DR: If your GPU supports instancing check out the higher performance/quality grass on Devtest4! Note that the new grass wind/displacement shader isn’t properly finished yet, however.

This is where I spent most of my time this week, rewriting the grass/foliage system. The current maps PEI, Washington, etc all use Unity’s built-in terrain grass (Devtest4 is using the new system), but this rewrite is a big upgrade in every way:

The old grass has a significant FPS stutter when a new camera is enabled (equipping a scoped weapon) and when moving around the terrain, which are no longer present in the new one. Foliage information occupies only a small amount of memory and is streamed in/out on a separate thread as you travel the map.

Rendering is done with hardware instancing, although note that this means grass performance will likely be worse than before for you if your GPU doesn’t support instancing (and much better than before if it does). You can check the instancing performance difference with the foliage.force_instancing_off command.

Another limitation of the built-in terrain grass was that it could only be placed/baked onto the ground, but now the new grass will automatically be generated both on the landscape and any surface with foliage information like the grass meshes used for overhangs or above tunnels/caves.

Foliage baking rules are also much better than before where each surface (terrain material, object) references a foliage collection asset which contains a list of different foliage asset types like grass, rocks, bushes, trees, etc which then can each have different rules about where/how they are placed. Those classes can also be extended for very customized situations.

The next terrain upgrade will focus on:

If you try baking foliage in the devkit on a custom map it will currently freeze up for a while, but don’t worry it hasn’t crashed. A future update will add a progress bar for this.
