I am dragging materials from Material Editor to Library folder in Rhino. My material names are formatted: [my.material.name] with dots as separators. Once dragged, the *.rmtl file that gets created is reformatted to [my_material_name].rmtl !
Why is that happening? I can then ‘by hand’ replace _ with . and all works just fine. Is there a reason why this is happening, or just a bug that should get fixed ?
