How to make an LED screen in Blender


Blender Guru just dropped a new tutorial! He uses geometry nodes to instance the LED screen lights, and then a raycast node to detect where a text object intersects the LEDs. Where an intersection occurs, the node switched the LED model to one with a bright texture. it sounds simple, but there are a few pitfalls to avoid, which will be pointed out.

Download links for fonts, textures etc are available in the video description.
