SilverwingVFX shows how to populate keyboard lettering using a shader rig procedurally.

This new tutorial from SilverwingfVFX (Raphael Rau) shows how to dynamically populate the labels on a keyboard by creating a shader rig using Cinema 4D and Octane Render.

The tutorial covers creating the texture legend and using a UV transform and other tricks to create a shader tree in Octane render that can show a different key label based on how many instanced keys are in the scene.
