Preface

The most open in the world 、 State of the art real time 3D Creative tools , The unreal engine will bring unprecedented degrees of freedom 、 Fidelity and flexibility , Help game developers and creators from all walks of life to create a new generation of real-time 3D Content and experience . Build a broader world
How big is the heart , How big is the world . Unreal Engine 5 Will provide you with the tools and assets you need , It enables you to create a truly vast world with content that is easy to scale up and down , For your players 、 Participants and stakeholders explore . Disruptive High Fidelity Technology
Nanite and Lumen And other groundbreaking new functions will create an amazing immersive and realistic interactive experience , Bring a leap across the times for visual fidelity , Make the scene full of vitality .
Dynamic global illumination and reflection
Lumen It is a completely dynamic global lighting and reflection solution , When the direct lighting or geometry in the scene changes （ Such as , The angle of the sun varies with the time of the day , Or open the outdoor door ）, It will immediately adjust the indirect light accordingly .

With Lumen, You no longer need to edit the lighting map UV And wait for the lightmap to bake , There is no need to place reflection acquisition ; You can directly see the same effect in the editor as on the host . Quality or performance ？ You can have both now ！
Next generation console players want to enjoy on high-resolution displays 60FPS Or higher frame rate , This puts great pressure on rendering resources .

Timing super resolution （TSR） It is a high-quality up sampling system built into the illusory engine , Platform independent , Through it , The engine can render at a lower resolution , However, the pixel fidelity of the output can be close to that of the frame rendered at a higher resolution . Quote official “ brag ” Words , however UE4 The cow is blowing UE5 Basically, it has been realized .

One 、 Terrain editing tools

although ue4 It provides loading grayscale map or height map, which can directly generate terrain , But we also want to create our own terrain , We can use ue4 Its own terrain editing tool . When I was running, I found ： The spline does not show . After a long time, I finally found the reason and recorded it ：

Two 、 Use steps

1. Select terrain mode

In edit mode ：

In operation mode ： Normal condition

Terrain programming shadow ！！！！ Obviously there's a problem

2. Question why

Wrong material orientation , Both the up axis and the forward axis are made x It's too late , Change the upward axis to x Axis or y The axis is fine

3. The normal operation

summary

This article mainly deals with UE4（unreal engine4） The problem of unable to display splines in terrain editing tools , If you want to create a terrain like me , Later I will write a complete article about using ue4 Edit Terrain tool , Coming soon , thank you
