Mount an LED display on the car

Development Asset Creation

Hello everyone,
I’m a beginner developer working with Unreal Engine.

I’m trying to attach an LED display to a vehicle, and the display should show some text.
I would like to assign a key so that when the key is pressed, the text on the LED display changes.

Could you please check if my current approach is correct?
If there is a better way to implement this, I would really appreciate your advice.
(I’m working on Ubuntu 20.04 with Unreal Engine 4.26.)

My current approach:

  1. I was provided with a pre-built vehicle Blueprint, which runs correctly. So I only need to add the LED display with changing text.
  2. I scaled a basic Cube mesh and attached it to the rear of the vehicle. Then, I created a Material with text on it, which I’ll call LED_1.
  3. I created another material with different text on it, which I’ll call LED_2.
  4. Initially, LED_1 is active. Upon receiving an event input (key press), LED_1 is turned off and LED_2 is turned on. I haven’t set up any physical interaction for now.

Additional Note:

In step 2, I’m using Text Render to create the material that contains the text.
However, I encountered a bug where the Font Cache Type won’t change to Offline.
Has anyone else experienced this issue or found a fix?

Thank you in advance!
