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...
