OpenJSCAD plugin - exporter

[gilboonet]

Hello, here is what I got when using your test file with my workflow.

I added materials from colors (select body, RMB, Vertex Attributes, Colors to Materials) then exported it to obj.

On the .jscad file, what I take from the materials is for each face the group where he belongs, and it is on the member called 'groups'. This information can be replaced by face color.
