ue4 blueprint

In 2014, UE4 suddenly took out 3 mobile platforms of Techdemo, respectively Soul:http://www.youtube.com/watch?v=jzgrbgb-fog Zen garden:http:// Www.youtube.com/watch?v=OK_gtNJ0Olk Rivalry:http://www.youtube.com/watch?v=jasgf9k7eyq (PC version porting) From 2012 to 2014 for three years, the computational power of the mobile GPU has increased by more than more than 10 times times from hardware Gflops view: http://kyokojap.myweb.hinet.net/gpu_gflops/ At p

Recently implemented a real-time mesh vertex animation in UE4, with a large number of vertices (hundreds of thousands of levels) The first is to create the dynamic Vertex Buffer, then each frame to update the vertex data, found that the efficiency is lower The bottleneck of efficiency is in the calculation of vertex coordinates, after all, there is a lot of Then changed to be based on vertex Texture (material in the World Position Offset) Implementati

I. Defining an array of struct bodies 1. Create a struct: first create your own custom structure: http://blog.csdn.net/liuqiqi0071/article/details/77196338 2. Create an array: Create a variable in the Blueprint class, assign the variable type to your own custom struct, and change the type of the variable to an array, refer to: http://blog.csdn.net/liuqiqi0071/article/details/ 77186167 the creation of an array of a struct of its own definition is com

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

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).

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
