The default, open UE4 Editor, the video card will render the scene at full speed, on my machine, is 120FPS. The whole machine began to roar and the resources were too much occupied. In fact, there is absolutely no need for this, the frame rate of about 60 is enough.How to modify it, try a lot of ways, the most effective is to modify the Baseengine.ini configuration file, modify the following line:Smoothedframeraterange= (lowerbound= (type= "erangeboundtypes::inclusive", value=5), upperbound= (Ty

to the right-click, add Event-in the blueprint. Custom events can specify input parameters, and can also specify whether the event can be synchronized on the client and server side.Replication has four options, which are not replicated by default, can be selected for multiplexing, run on the server, run on the client to which it belongs, and can be selected if the event needs to be routed over the network.Enter a value column to add parameters, the same type as the variable type.Let's do an exa

Unreal Engine 4 RenderTarget making live camera effectFirst on the effect:Live camera I do not know how to translate, anyway, the meaning is to render a camera image to a 2D plane.The following are the specific implementation methods:1. Create a scene Capture 2D objectDrag the object to the appropriate place.2. Create a Rendtertarget objectRender target, Material

In the latest version of Unreal Engine 4.4, the Physicsconstraint in Blueprint is Bug-Blueprint cannot edit constraint's two actor components, and the only way to do this is through C + + code. There are many such questions, fortunately, the source code to you, and how to change with their own.I want to implement the role swing function in the Thirdperson template, just like the Persian monkeys.First, add a

Unreal engine 4 C ++ is used to draw functions for debugging. UE4 provides many predefined debugging and rendering functions, which are convenient during debugging. You can draw points, lines, circles, balls, arrows, cubes, capsules, and even splines, strings, and grids in a scenario. What's better is that you can control the line thickness, Which is intuitive du

To implement camera latency, you only need to modify the attributes in the lag column. The first one controls the latency when the camera moves, the second is the latency when the camera rotates, and the other two are the latency speed. The smaller the latency, the mo

For people like learning the fundamentals of game engines, they need to set their own clear long-term goals:1 First, there may be no concept of the game engine in the beginning, it is recommended to use one or two game engines first (I recommend C + + programmers to learn Unreal
