I have a robot character in Unreal Engine, it has a helmet with a visor . I want to feed the LED, custom text and emoji. as you can see Daft Punk Helmet is what I Need. They feed custom text, shapes and emojis to their helmet visor and it displays it in LED, but in My Case, I’m stuck with static text textures, or playing animated mp4s to playback video files with an emission material on the visor.

I don’t want to use static textures or videos for it. I want to be able to Type in custom text and emojis in the editor and change the text in runtime in blueprints, and then the text will be converted to a texture (probably using render target) and then used in the visor led as an emission material. But I can’t think of how to actually do this.

I kinda did it, and achieved the effect. not the correct & acurate way, but at least a workaround.

I added a widget component in my character pawn blueprint, made a dedicated widget only containing that text (with an custom event to take string inputs and change the text)

but the main trick was that the widget component, has a Geometry option, and when you set it to cylinder, you can specify your bend degree. I tried to match that with my character visor, and it kinda did the job, but not really exact.

now I can type inGame in real-time and it appers on the visor in real time.
