Open UE4
UE4 specific new project operation is here
Then click the content
Right key Alt+left key Alt+middle key is to change the view
It is recommended to create a new pipe card directly below. The new level above will have some default configurations that are inconvenient.
Then click don't save
pull three things in
Then open the Details tab
Change the light source of the sky sphere
At this point, changing the light source will display the corresponding effect
When the light goes up at 90 degrees, it is actually night.
Click Refresh Material
It can be seen that it is displayed as night at this time
Pull an object and plane to see that there is a shadow at this time
Spaces are toggle operations (translation, rotation, scaling)
Then delete the cube and plane
Create a new folder below and pull in what you did before C4D
Digital twin material transformation ( 3 ) ?spm=1001.2014.3001.5501
When importing a road, pay attention to check it to prevent it from being stuck as shown below
When importing terrain maps, you can directly reset them all to default.
After importing, select all models and import them into the scene (do not select materials or textures)
The trick is to first select the last one such as highways and then hold down shift to select the first model
Then select all the models just imported to reset the position
Create a folder with all models selected (the folder icon in the upper right corner)
then make it night
Next is the material
selected building
Double click on the material
In the editor, right-click to move the view
Press and hold Alt + Left button on that connection to cancel
Right-click search vector
Just click the first one
add another constant
Add another 2D vector
Or press and hold the number keys 1, 2, 3 + the left mouse button, and one, two, and three-dimensional vectors will appear.
change one dimension to 1
Double-click the three-dimensional one to turn it blue, click OK, and then click again, it will turn into the following image
Then make a drag connection
Let's first introduce the function
The second one is to use one-dimensional vector connection for metallic feeling, which is to give the model the corresponding metallic feeling.
Color needs to be represented by a three-dimensional vector (because it is three dimensions of rgb)
Add a self-illuminating color building here and it will glow
If you want to increase the luminous intensity, drag another one from the node and enter*
Make the glow effect ten times stronger
The effect after saving is as follows (the following is the enhanced lighting effect)
At this time, if you want to become striped and glow, multiply it by a texture
The following is the texture I drew myself, which can be used in screenshots
From a programming point of view, it means that the black multiplied by the color in the material is the non-luminous part. Black represents multiplied by 0, and white represents multiplied by 1.
add one more function
The function of this api is to scale the distribution of materials on the model
I changed the v-tile to 2, and it is denser in the v-axis (i.e. the y-axis direction)
Panner This is to make the material scroll on the corresponding interface
Converted to parameters to facilitate calling from the outside world
Create a material instance to facilitate the next direct call
Now create a material for the previous lattice
Drag the created bare material directly to the right
Then adjust the road material
Note that the road must have a height (position z), a width and a length (x, y)
Remember to save the project (Save all options below)
Otherwise it's gone
Finally, optimize the sky scene
First, mention the sky ball material downloaded from the official website

Extraction code: 2f28
-- sharing from Baidu Netdisk Super Member V4
After decompression, copy it into the project (my location is F:\Documents\Unreal Projects\SZ_change\Content)
Then enter ue4 to select the content and enter the selection path
Click on the content of this parent directory
Click on it in the order of the directory to find this sky ball
Then the location resets to default
Delete the previous sky ball
