What is the best practice for creating a font with a 3D extrude effect like this created in multiple glyphs or master files?

I’ve been learning Glyphs 3 for just a week. I’m trying to create a 3D extrude style font by splitting it into 3 font styles (fill1, fill2, and shadows), like in the screenshot.

Can these styles be made into 3 masters, or do I have to make 3 separate Glyphs files?

Thank you to anyone who helps answer this question!

This is best done using color fonts, all in a single Glyphs file. There are different techniques for color fonts. The two best for the example you posed are these:

If we use a color font approach, can each style be exported separately into three different regular OTF/TTF fonts like in the picture (Style 1, Style 2, Shadows)? I’m taking concept references from Dr. Slab by Dharma Type: https://dharmatype.com/dr-slab

Yes, try this example which defines different instances, one per TTF/OTF export:

Thank you for your help! I’ll start learning it!
