Copy this material to our new folder

Enter this material , Improve this material

 

 

  These four nodes are the same , Let's just keep one .

Let's add a multiplication node

attachment

 

 

  Add two constant nodes （ Shortcut key ： Press and hold the keyboard 1 And the left mouse button ）

Convert to parameter

 

  named scalaru,scalarv, Turn two variables into vectors

 

  The default values are set to 1

  Save and create material instances

  Set the parameters of the material instance here

Material the wall

  This brick is too long , It's too big , We have to change the proportion , Open the material instance , Modify the parameters we set .

Use examples of materials 1 Install , It's very abrupt , We instantiate a new , Modify the parameters .

  

  It's quite appropriate to look at it like this .

Similar operations introduce floor materials , I won't record it

The final effect

 -------------------------------------------------------------------------------------------------------------------------------

Add a glow effect to the fireball explosion

Add a point light , On the sphere of the fireball .

  At this time, the ball itself is luminous , But there was no light when it exploded , This is a little fake .

  We also install a point light component on the explosion blueprint .

In this case , After the explosion, a light was left in place .

  therefore , We should be exploding actor After being summoned , After a while ,destroy Drop this actor.

We open the blueprint of blasting , Complete this operation in the game start event .

  test ： I found that the smoke and light of this explosion disappeared at once , It's too stiff .

We should be destroy Point light component , Not the whole thing actor

  The test result is OK .
