repeated removal , will be the actual Shader Code is stored in Shaderlibrary and only Shadercode GUID is stored on each Materialinstance object, which greatly reduces the actual shadercode size. In some projects you can lose 80%. In addition, the unused rendering function must be switched off in the project settings, which can greatly reduce the number of combinations of shader splits . 6.4 RHI (RHI Meet again )manyoptimized adaptation and Iter

UC Project is a foreign big capital of a UNREALENGIN4 project, why to analyze the project, because it is small enough and enough complete, unlike the official open-source UT, it is too large, and unlike other demos which only a technical point, These demos do not solve the Ue4 game engineering problems and process problems, such as the game's various menus (Main Menu/Pause menu/production staff, etc.), the switch between the levels, and even many peop

How should I connect to the server if unreal 4 only serves as a client? The official website does not provide blueprint network functions, which are available in C ++. 1. implement it by yourself and provide interfaces for blueprint use. 2. Third-party plug-ins. Plug-in: https://github.com/feixuwu/UEWebsocket 1. You have installed vs2015 or vs2017 and the c ++ component. 2. create a C ++ project, or create a new C ++ class in the blueprint Project (it will automatically convert the blueprin

First use UE4 to create a simple example of what you like to project, official, and then start your packing trip. The way to iOS As we all know, we have itunes installed. After the installation is successful, there are optional devices. When clicking on the Apple device, or the following error occurred. Anyone who believes in compiling the iOS version knows that if you want to package the project, you need a developer account.

Find the UEBuildWindows.cs file that records the version of the VS compilation that this version of UE4 can use Like what 4.19.1 version public enum Windowscompiler {// Version 4.9 Public enum Windowscompiler { ///visual Studio (Visual C + + 11.0). No longer supported for building on Windows, but required for other platform Toolchains. VisualStudio2012,///Visual Studio (Visual C + + 12.0) VisualStudio2013, ///Visual Studio + + 14.0) VisualStu

Add a Class wizard in the class editor to generate the files and underlying macros required by the class Header file because UE4 has extended the C + +, it implements features such as serialization reflection, similar to QT practice: Add some macro keywords to the code and generate the corresponding C + + code during compilation. Therefore, for each class, there is a file that generates a Classname.generated.h class declaration Uclass ([specifier, s

UE4 There are many module, gameplay part is also one or more module, each Editor is also a module search, module total 170 +, a total of three categories: Runtime, Editor, Developer Runtime This is more important than the core, Uobject, Engine core data Type Database Container Io/log uobject: The base class for all objects. Another convention in UE is that object reflects the serialized package Engine actor, which is not an actor: a collection of Comp

PS: In project management, FBX file upload, get, import and export is a very important piece of content, especially the animation FBX file import UE from Max/maya One: Unreal4 file import absolute path and relative path Usually the file is placed in the content directory, the open project will detect itself and ask the user whether to import, if it is outside this directory. We wanted to get the path when we managed to manage the files in the team and not pack them. The location of the

the following blueprint will use the default value of this Id,text component as AAAA, as shown in the structure:5. Open the graph panel of the widget Blueprint and right-click to create a custom Event6, this custom event name is Changetxtevent, because to accept the MYPLAYERCONTROLLER_BP blueprint passed in the string type parameter, so here is also a new string type parameter, named Newparam.7, finally using the Blueprint node to connect the implementation logic, we bind in the event construct

NavMesh, this one demo can not see what the pros and cons, editing up to is very convenient Role control, like UE3, or Character+controller way, Character (Pawn) responsible for performance, controller responsible behavior. For AI, it is derived aicontroller to implement custom AI behavior Unlike UE3, blueprint can replace many of the original scripts. In addition, UE3 is more dependent on the built-in state machine in the script for AI behavior control, UE
