WTF Is? If the rendering information of a Child Widget changes, the Invalidation Box will be notified to recalculate the Prepass and OnPaint to update the cache information. Assuming that we know that the upper limit of the B_HeroIcon appearing on the screen at the same time is 20, then we can create a Render Target Pool containing 20 Render Targets to make different Retainer Boxes. I tried the Github version too but was unable to get it to build successfully. 2.3 Other optimizations 2.3.1 C ++ development Except for the design reason of UI animation, this storage structure cannot be implemented in C ++, and other UI functions can be implemented in C ++. It doesn't make sense to place the Invalidation Box above the Retainer Box. They're redrawn every frame, including all … The code to remove the reference relationship in the Cook phase is as follows: The code to load the texture is as follows: The code to release the texture is as follows: 2.3.4 3D RTT optimization By default, SceneCaptureComponent2D is ticked every frame, and you can usually cancel updating the image every frame: The update frequency of the animation is sufficient 30 times per second on the phone, so you can set the Tick interval setting of SceneCaptureComponent2D through the blueprint: Then manually call Capture in the blueprint: In addition, the size of the Render Target of SceneCaptureComponent2D should not be too large, which helps to improve performance. (Inherited from TextBoxBase) Multiline: Gets or sets a value indicating whether this is a multiline TextBox control. 3. share. The first method is to split the Invalidation Box, and split them into different Invalidation Boxes according to whether the Widget changes frequently. Text Widget affects the properties of Draw Element: Progress bar Widget affects the properties of Draw Element If you use Widget Binding on the attributes that affect the Draw Element, it will cause the engine to Tick every frame to check whether the attributes have changed, so as to determine whether the Draw Element needs to be updated, so you should avoid using Widget Binding. In many cases, reducing Draw Calls does not bring about an increase in FPS. ini will change max amount and lifetime for blood Widget Tree: Each User Widget is stored in a tree structure. Describes the process for connecting UE4 to Motionbuilder with the Live Link Plugin Animation Node Reference Descriptions of the various animation nodes available for use in Animation Blueprints. Collapsed does not occupy layout space (Layout Space), so it will not perform Prepass calculation after hiding, and its performance is better than Hidden. UE4 provides a wealth of functions and debugging tools, and mastering these functions can help developers achieve high-performance UI. The opening method is located in Project Settings: "Engine-> Slate Settings-> Constraint Canvas-> Explicit Canvas Child ZOrder". If Retainer Box is used, Draw Elements will be rendered to Rtain Target of Retainer Box. Audiokinetic's Community Q&A is the forum where Wwise users ask and answer questions within the Wwise community. We have received some complaints from domestic developers before. 2.2 Rendering thread optimization 2.2.1 Merging batches With the development of GPUs, the impact of the number of Draw Calls on performance is getting smaller and smaller. info-contact@alibabacloud.com The User Widget B_HeroIcon is repeatedly used in multiple main interfaces such as HEROS and SOCIAL. For example, the following figure shows that the Retainer Box is updated every 3 frames and updated at frame 0: The following figure shows that it is updated every 5 frames and updated at the second frame: Then every 15 frames, these two Retainer Boxes will be updated at the same time within a frame, resulting in a decrease in the number of frames. It is recommended to view the time overhead of counting thread variables through the following command: stat dumpave–num = 120 –ms = 0.5 The statistics of the three key indicators are: Slate Tick: Statistics thread variable STAT_SlateTickTime. Try to use Grid Panel, Vertical Box, Horizontal Box, and other containers that support merging batches. How about buyvm.net space? If the Retainer Box contains clickable widgets, you need to set the Retainer Box to Visible so that the engine will map the click test area to the Retainer Box. Widget Render: Statistics thread variable FWidgetRenderer_DrawWindow. In addition, Widget Binding is executed every frame Tick, the performance is relatively low. I noticed that there was a commit on Github which mentioned there were fixes for 4.15. 40 million players a month! Dmitriy Dyomin of Epic Games provides an idea for easy and quick replacement. Prepass: Traverse the tree from bottom to top to calculate the ideal size (Desired Size) of each Widget. In many cases, the UI does not need to be rendered every frame, so the rendering results can be cached through the Retainer Box and updated every few frames. Retainer Box will create a Render Target for each User Widget instance, so without changing the code, the reused User Widget should not use Retainer Box. In this case, you can extend the Retainer Box to support the event-driven approach. The last User Widget will generate one or more Draw Elements and pass the Draw Elements to the rendering thread for rendering, where each Draw Element corresponds to a Draw Call.

Others. (Game thread). If you don't set the texture in the editor, you can avoid referring to this texture object in CDO (Class Default Object). It’s been almost a month and we will need to make the engine update soon because of new features added in the engine. The following figure demonstrates another situation. It works like on the same level. UMG doesn't work on top of UT, UT doesn't rely on UMG (nor control it somehow). Major Features Performance and Multithreading A major effort for us over the last several months has been optimizing UE4 in order to get our next game, Paragon, running at 60fps on PC and PlayStation 4. At this time, you can check the Cache Relative Transforms corresponding to the Invalidation Box, as shown below: Then when the position of the User Widget changes, the engine will not update all the Draw Elements (that is, Vertex Buffer), but will modify the Shader parameters (View * Projection Matrix) to reflect the position change. The effects of continuous expression (such as 3D characters, material effects) can be separated from the Retainer Box, but need to pay attention to the pixel fill rate, it can also be solved from the aspect of special effects design. 二、通过外界给Invalidation Box内的子控件赋值，子控件是会更新的。只有子控 … 2.2.4 Switching materials UE4 provides a wealth of material effects. The Retainer Box area should be as small as possible to help improve rendering efficiency and reduce video memory usage. Tick will calculate Prepass and OnPaint, but the overall Widget Tree cache will not be affected. Then you can set the ZOrder property of the Child Widget of Canvas Panel. Since the application opened Mobile HDR, the bottleneck was on the GPU, so the FPS did not improve much. If a User Widget is too complicated, you can split it into multiple Invalidation Boxes, and put the Widget into different Invalidtion Boxes according to the update frequency. Dotted box: Widget labeled Volatile. Set widgets to collapsed (not hidden) when you don't want to show them. … Invalidation Box：使条目无效的容器。使容器内的条目不再更新，如果确定某一个UI不需要更新的话，就可以把这个UI放到Invalidation Box中。 一、Invalidation Box是一个性能优化容器. It is not recommended to use this function in the project, it is recommended to pass values by calling functions in C ++ (or blueprint). Of course, we do not want to create a Retainer Box for each B_HeroIcon. 2.1.3 Widget Binding When analyzing Volatile, it was mentioned that Widget Binding will cause Volatile to reduce UI performance. The operation method is as follows: All Prepass and OnPaint calculation results under the Invalidation Box will be cached. EBCCA6E2-9938-49B2-90F4-B20C16A29B83.mp4.

Slate Render: Statistics thread variable STAT_SlateRenderingRTTime. [UE4]Invalidation Box. Gets or sets a value that indicates that the text box control has been modified by the user since the control was created or its contents were last set. When the rendering information of a widget changes, it will notify the Invalidation Box where it is located to re-cache Vertex Buffer. It is recommended not to use Canvas Panel. Using Retainer Box not only improves the efficiency of the rendering thread, the game thread's Tick will be executed once every few frames accordingly. At this time, a better Retainer Box effect can be achieved by extending the code. Home > Add this widget as a child to the wrap box in our current widget. Each Widget lists in the ComputeVolatility function which attributes will affect the Draw Element (Vertex Buffer). If a large number of widgets are set to Visible, the efficiency of the engine when clicking on the response will be greatly reduced, which will also increase the overhead of the game thread. Invalidation Box：使条目无效的容器。使容器内的条目不再更新，如果确定某一个UI不需要更新的话，就可以把这个UI放到Invalidation Box中。, 二、通过外界给Invalidation Box内的子控件赋值，子控件是会更新的。只有子控件自身代码引起的变化会被Invalidation Box禁止更新。, 三、Invalidation Box.CanCache：Invalidation Box的子控件是否可被更新，true可更新，false不可更新。, 1、创建一个名为“CountsWidget”的UserWidget，添加名为TextBlock_1的TextBlock，并在TextBlock_1的Tick事件中递增一个数字：, Invalidation Box.SetCanCache可以设置子控件是否可更新。, 4、点击“Toggle CanCache”按钮开始更新，再点击一下“Toggle CanCache”按钮，数字停止在31并停止更新, 5、过了一段时间，再点击一下“Toggle CanCache”按钮，数字从31开始继续更新，而不是Invalidation Box的子控件实际在更新，但被Invalidation Box阻止在界面上显示出来, 6、Invalidation Box的子控件完全停止，所有一切互动都静止，包括tick事件也不会被调用。.

Use AssetRegistry to replace Texture with Sprite, and finally save the Widget Blueprint Asset. 2.3.3 Free texture memory One premise for releasing texture memory is not to set textures (Image item in the figure below) during editing, but to manually load textures, set textures, and destroy textures through the program. A.Panel Widget In engine versions prior to 4.15, Canvas Panel does not support batch merging. [UE4]Invalidation Box. Retainer Box will consume additional video memory, so it is necessary to control the amount of usage and give it priority to the User Widget with the greatest performance improvement. The operation method is as follows: All Prepass and OnPaint calculation results under the Invalidation Box will be cached. The LevelUpIcon in the above picture is usually hidden, and will be displayed when the character is upgraded. You can use Slate.InvalidationDebugging to check whether the Invalidation Box and Volatile are set correctly. If you need to switch between independent textures and merged textures in the logic code, in Manager Class, initialize the independent textures (UTexture2D) and merged texture resources (UPaperSprite), and create FSlateBrush, set the resource to FSlateBrush through SetResourceObject. Panel Widget: It will not be rendered and used to lay out Child Widget, such as Canva Panel, Grid Panel, Horizontal Box, etc. Slate Render: Render Draw Elements to Back Buffer.
