Blender export - using vertex colors and mixing

[Sasha]

Hello. I'm beginner in Blender and babylonjs. I want to make model of book with dynamic stitching changing in babylonjs. I use mixing of two materials and different vertex colors in Blender nodes for this(vertex colors split two materials and are used in Geometry node). I used this exporter https://github.com/BabylonJS/Babylon.js/tree/master/Exporters/Blender  but after exporting I didn't find any information about my variants of vertex colors and mixing in babylon file. How can I get and use this in babylonjs?

The exporter does write vertex color geometry, though I do not know how you make them.  Your picture of cycles nodes is not looking encouraging.  For cycles, the most the exporter will do is automate a texture bake.  If cycles can take into account vertexes, seems like this could be too early.

Thanks. I found vertex color in babylon file, but only one variant had exported. I want to change them by id in babylonjs. Can I do anything in Blender for exporting all variants(not only active)?
