Custom clothes for UE Metahuman / UE4-5 / Blender 3+ /MarvelousDesigner 11

For the past couple of days, I have struggled to find a suitable workflow for adding custom clothes to my Metahuman characters. It frustrates me to sit through hour-long videos that could have been easily condensed down to 10 minutes. Keep in mind, this is just a step-by-step clickthrough and not a tutorial about “How to create clothes in Marvelous Designer“ or “How to correctly Weightpaint in Blender“. This workflow is suitable for UE4 and UE5, Blender 3.0/3.1/3. and MarelousDesigner 10 and 11
