I use two software programs to make it sparkle.
GIMP&Blender.
In simple terms,How to make it sparkle.
In GIMP I create a normal map.
In Blender I load the VRM.
And Then I change the shader to PBR.
Next I add a normal map and set it to metal.
awe.. you so sweet, makes me want to continue making more lol
actually I’m looking at her sparkly suit again, just thinking it would make
a great mermaid tail, I love the way it sparkles.
