Transfer 'color by layer' to 'color by material'

[rv1974]

Have you seen the plugin that does the subject?
Thanks in advance

To clarify...
Do you mean, to take each layer's color, and use that color for a [new] material [probably named based on the parent-layer's name?], then apply that material to all entities which are assigned that layer.

If so try this... copy+paste+enter in the Ruby Console.

mo=Sketchup.active_model
cs={}
ns=[]
ls=mo.layers
p ls[0].name
ls.to_a[1..-1].each{|e| #skip Layer0
  cs[e.name]=e.color
  ns<<e.name
}
mo.start_operation('lcol>>mcol',true)
ms=mo.materials
ns.each{|k|
  m=ms.add(k) unless m=ms[k]
  m.color=cs[k]
}
mo.entities.each{|e|
  e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
}
mo.definitions.each{|d|
  next if d.image?
  if d.group?
    d.entities.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
    }
  else #compo
    d.entities.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
    }
    d.instances.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
    }
  end
}
mo.commit_operation
puts

It's one step undoable.

It currently skips processing 'Layer0' - but to include it change:
ls.to_a[1..-1].each to read ls.each
and add a new # in front of the 4 lines **#** unless e.layer==ls[0] #Layer0

Toggle between Material and Layer view settings to see the effect...

Works almost perfect. Please check PM.
Many thanks!

Transparency [alpha] in colors used 'by layer' is not detectable - I think?
It always returns 255, even when it displays as less !
Neither is a layer's 'texture'.

This version also processes 'back-face color'.

mo=Sketchup.active_model
cs={}
ns=[]
ls=mo.layers
p ls[0].name
ls.to_a[1..-1].each{|e| #skip Layer0
  cs[e.name]=e.color
  ns<<e.name
}
mo.start_operation('lcol>>mcol',true)
ms=mo.materials
ns.each{|k|
  m=ms.add(k) unless m=ms[k]
  m.color=cs[k]
}
mo.entities.each{|e|
  e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
  e.back_material=ms[e.layer.name] if e.is_a?(Sketchup;;Face) && e.layer!=ls[0] #Layer0
}
mo.definitions.each{|d|
  next if d.image?
  if d.group?
    d.entities.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
      e.back_material=ms[e.layer.name] if e.is_a?(Sketchup;;Face) && e.layer!=ls[0] #Layer0
    }
  else #compo
    d.entities.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
      e.back_material=ms[e.layer.name] if e.is_a?(Sketchup;;Face) && e.layer!=ls[0] #Layer0
    }
    d.instances.each{|e|
      e.material=ms[e.layer.name] unless e.layer==ls[0] #Layer0
    }
  end
}
mo.commit_operation
puts

Amazing! Many thanks.
P.S. Please publish it it Store so it won't get buried in forum.

Let's wait a day or two until it gets fine tuned...
