Illuminated characters

[miht]

Idea - illuminate the characters based on the distance from the marker.

Approach #1: Multiple textures, no need for light source:

• One plane with a texture for masking out the letters (making the letters 100% transparent)
• One texture beneath the previous, white diffuse
• A plane with an emissive radial gradient texture, following the marker around the field and placed in between the two previous textures.
