To get the best performance possible from the Landscape system, there are certain technical restrictions that have to be adhered to. The following document aims to bring these restrictions to your attention as well as provide you with valuable information so that you can strike the best balance between beauty and performance with your Landscape.
Valid dimensions for Landscape heightmaps are not always immediately obvious when getting started. Being able to determine what dimensions for heightmaps are valid and, beyond that, which are optimal requires a thorough understanding of the underlying architecture of the Landscape.
In order to create a system that allows for huge terrains while still being efficient in terms of memory and performance, the architecture implicitly applies restrictions on the dimensions of the heightmap, meaning there are certain dimensions that are valid and others that are not.
In previous terrain systems in Unreal Engine, there were either no restrictions i. The restrictions on heightmaps for Landscapes are much more complex and rigid. A Landscape Actor is color coded so that it is easier to tell what each section does. The edges of the Landscape are highlighted in yellow, the edge of each component is in light green, section edges if set to 2x2 sections in a medium green, and the individual Landscape quads in a dark green.
Landscapes are divided into multiple Components, which are Unreal's base unit of rendering, visibility calculation, and collision. Components in a Landscape are all the same size and are always square.
The size of the Landscape component is decided when the Landscape is created and the choice depends on the size and detail of the Landscape you wish to create. Each component's height data is stored in a single texture. Because of this, its size has to be a power-of-two number of vertices. The shared row of vertices along the edge of two neighboring components are duplicated and stored in each component. For this reason, it makes sense to think about the number of quads in each component.
A very simple Landscape is illustrated below outlined in green containing four components. Each component is made up of a single quad. One component has been separated to show how the vertices where the components meet are duplicated. Components can optionally be divided into either 1 or 4 2x2 subsections.Resolution Issues.

Previous template Next. Resolution IssuesPM. Hello, I started the game up and it loads fine but when it loads up it only shows parts of the menu and i cant see the menu at all on my screen. The game seems to start up fine but it seems it starts in a small resolution and its zoomed in on the unreal logo. Is there anyway to change the resolution or switch to windowed mode in the files at all?

Should be a simple fix if the devs are aware of the problem. Unreal Gladiator. The game will only apply a resolution change for me once. Even though it will only change the resolution once while in game with out restarting to the game it still changes the resolution in the games ini file. This is with the February 6, build.

I tried to change the resolution this way after i saw that the game wasn't changing it to p for me. Whenever i try to change it the game writes over it and resets to default. UT Style. Yes No. OK Cancel.Keep in mind that the more you scale your settings, the more it will change the look of your work, and some rendering features may even be disabled in lower spec settings. These settings are saved each time you exit the editor, so you may try restoring the settings to see the final look on a high-spec machine.Cv rotate
Over time we will continue to refine the system for details see BaseScalability. We have many features that we can adjust for performance or quality. All of those settings are grouped e. Which settings are the best for you depends on your configuration CPU performance and memory, GPU performance and memoryyour personal preference pretty or fast and the content many objects or complex materials. The auto button gives you good settings for starters.
Note that lower settings do not always result in faster rendering. This can happen because many specialized hardware units run in parallel. Scaling down a specific rendering feature might not affect the critical path and in that case it would have not resulted in better performance.
The engine is optimized for a typical game workload realistic materials, many lights, partly dynamic, many objects, and many effects and a wide range of target platforms.
Some hardware might just be too slow to run the editor but a modern desktop not laptop multicore CPU with a decent DirectX11 graphics card should give you a very good experience. The game settings are stored separate from the editor settings.WTF Is? Apply Non Resolution Settings in Unreal Engine 4 ( UE4 )

I even tried changing the other resolution lines and also mesing with the "Fullscreen" like and setting it to 1 but that just puts it in Windowed Fullscreen mode. Did doing this work for you? Try setting your desktop at x resolution and then boot up the game!? Ursprungligen skrivet av Raigavin :. Same issue here. The only way is bordeless windowed mode. I started playing today amd went into game settings and I am perfectly running the game at p full screen mode with very high settings only disabling vsync.
Possibly a "C" or "D" series? Both the and models report inaccurate EDID info so Windows picks up the recommended resolution to be p. Also, worst case scenario create a custom resolution. Just to get the game to not crash to desktop I had to manually enable "Single display performance mode" in NV profile inspector. My second Ti sits there idle and wasted. Ursprungligen skrivet av zaster :. It is not working when DSRing from P however. I refunded the game anyway.

Obtaining the same look on modern game engines, however, can be quite difficult and requires some setup. This introduces some noticeable inconsistencies in the way sprites are aligned. The simplest solution to prevent this from happening is to snap the sprites to the pixel art grid just before rendering. Most implementations I could find online perform the snapping directly in the world, by conforming object locations to the grid just before rendering.
The original location is then restored on the objects at the beginning of the next frame. Unfortunately, this is cumbersome to do in Unreal Engine 4 the resources I found were for Unityand might have unwanted side-effects like triggering overlaps, for example.
As such, in Guntastic we ended up using a simpler approach: snapping is applied directly in the vertex shader by offsetting the sprite geometry vertices. This works on the assumption that the vertices of the rendering geometry of the sprites are aligned to the pixels of the art itself, so special care should be taken to generate valid rendering geometry.

In our implementation we apply the snapping at the end of the camera update logic, after everything else including special effects like screen shakes, etc.
This is how the actual code looks like:. Furthermore, rotating textures that use nearest-neighbor filtering introduces evident aliasing between pixels.
The simplest solution here it to avoid to physically rotate the objects in the worldand use hand-drawn rotated versions of a sprite where rotation is actually needed.
While developing Guntastic, however, we encountered some edge cases that still required to handle in-world rotations. An example of such cases are guided missiles, which need to track a target by pointing towards it: here the amount of rotated sprites to draw was simply too much to handle for a team with a single artist. This technique works by:. In other terms, it smooths out jaggies between pixels, while keeping the overall result crisp.
The only caveat when working with this technique is that linear filtering should be applied to the sprite texture instead of nearest-neighbor filtering.
Luckily, applying this inside the engine is straightforward as it only takes some discipline to never scale the sprites. The final step to ensure a true pixel-perfect look would be to render the game at the original art resolution, and upscale the rendered frame to match the actual screen resolution.
Unfortunately we hit a couple of major road blocks when trying to implement it, and decided to abandon it at least for now :. A simple material function that can be used to snap vertices to the pixel grid. Pixel snapping at work. Sprite render geometry vertices should be aligned to the pixel grid for the snapping to work correctly.

This technique works by: […] performing linear interpolation between texels on the edges of each texel in the fragment shader, but sampling the nearest texel everywhere else.
This almost completely eliminated the problem: Manual texture filtering at work.
Taking It Further The final step to ensure a true pixel-perfect look would be to render the game at the original art resolution, and upscale the rendered frame to match the actual screen resolution.Enabling Dynamic Resolution At Runtime.
Pausing and Resuming Dynamic Resolution. Testing Content with different Primary Screen Percentages. Dynamic Resolution adjusts the primary screen percentage according to the previous frames' GPU workload. The resolution adjusts as needed based on a heuristic, for example, when there are too many objects on the screen, or if there is an expensive effect that suddenly enters the frame.
Dynamic Resolution can be enabled by getting a boolean on the Game User Settings node. In Blueprintenable dynamic resolution by using the Game User Settings node to opt into the feature like so:. Game thread logic has the final programmatic control over when to actually enable or disable dynamic resolution, so if it's enabled at runtime using Blueprint that will take precedent over setting it in code. To restore game user settings to its original state, use the following:.
After enabling Dynamic Resolution, the following console variables set the minimum and maximum screen percentages, and the maximum budget of any given frame before it lowers the resolution.
There are default values that are in place until you do set them:. You can use the Device Profiles window in UE4 to set up the configuration files and manage them for you.
At times, you may need dynamic resolution enabled for project but not in areas like the main lobby. Dynamic resolution can be paused and resumed alongside Operation Mode. The following console variable can be used to set the Operation Mode of Dynamic Resolution:.How to use concept matrix ffxiv
The table below outlines the different states that are available when a specific operation mode is enabled or disabled and how GameUserSettings is affected:.
To check the status, use the node Is Dynamic Resolution Enabled. There are several stat screens that you can enable to debug performance with Dynamic Resolution.Train accident in new york yesterday
Stat Unit is used to look at the overall frame time as well as the game thread, rendering thread, and GPU times. The primary screen percentage is displayed here for the X and Y so that you don't forget that it is scaled on both axes. The UnitGraph can show the primary screen percentage that is chosen by Dynamic Resolution. The timings label of the graph will change to indicate that it's displaying raw timings.Expand all Collapse all.

Locked Aspect Ratio — When enabled, locks the Height value and scales it proportionally according to the Width and the Aspect Ratio values. Quality Presets — A slider for a set of presets. When changing the preset from the drop-down menu, the values of the overall settings also change.Navd88 maps
Auto Correction Mode — Specifies which camera to use the automatic exposure and white balance setting. All cameras - Auto correction will be applied to all cameras in the scene. Auto Exposure — Automatically determines an appropriate exposure value for the render. Auto White Balance — Automatically determines a suitable white balance value for the image. Time Limit Minutes — Specifies the maximum time in minutes for refining the image.
Noise Limit — A threshold that determines when to stop refining a pixel. Higher values allow more noise in the image, but the render is faster. Lower values help reduce the noise, but take more time to render. A value of 0. Sample Limit — Specifies the maximum number of samples per pixel for refining the image.
V-Ray performs adaptive sampling on the image, trying to put more samples into areas with more noise. GI Engine — Specifies the type of secondary engine.
