I am making a word game where each letter tile is represented by a plane. I was wondering, is there a more elegant solution for the creation of these letter tiles than making a .png texture for each letter in the alphabet, and then storing 26 materials for a plane? It just seems a bit ridiculous to have 26 textures for a plane. Thanks!
Create a texture atlas that contains the letters, and UV map the tiles as appropriate.
You could use a Text Mesh and a Mesh Renderer and then put on what you like - use several if you need small scores to be displayed. Arrange the Text Mesh above a cube or plane to make the tile.
