I changed a code from your suggestion , but faces change color without transparency.
What happens ?def gl_green model=Sketchup.active_model ss=model.selection faces = ss.grep(Sketchup;;Face) matl = Sketchup;;Color.new(0,250,154) matl.alpha = 0.5 faces.each{|face| face.back_material = face.material = matl } end
-
try changing matl = Sketchup::Color.new(0,250,154) to (0,250,154, 100)and
faces.each{|face| face.back_material = face.material = matl face.material.alpha = 0.5 }
edit: Updated code for backface as you wanted. And the 4rth argument is actually not needed in th Color object..

Setting alpha for face material inside the loop is not efficient. It'd be better set outside the loop.

Thank you so much !!! Love You All'
I changed as your suggestion , Jolran
It can change colors of glass now. I appreciate it !
There are many colors that I have to revise.
I will also change others as your example.
def gl_green model=Sketchup.active_model ss=model.selection faces = ss.grep(Sketchup;;Face) matl = Sketchup;;Color.new(0,250,154) faces.each{|face| face.back_material = face.material = matl face.material.alpha = 0.5 } end
-
def gl_green model=Sketchup.active_model ss=model.selection faces = ss.grep(Sketchup;;Face) matl = Sketchup;;Color.new(0,250,154) matl.alpha = 0.5 faces.each{|face| face.back_material = face.material = matl } end
No
You are jumbling up 'material' and 'color'.
Make your material then give it a color, alpha etc - then give faces that material...
More like this...matl = model.materials.add('gl_green') matl.color = Sketchup;;Color.new(0,250,154) matl.alpha =0 .5 faces.each{|face| face.material = matl face.back_material = matl }

Hi , TIG
This is correct , right ? I test it and it gives a name of material !!
def gl_green model=Sketchup.active_model ss=model.selection faces = ss.grep(Sketchup;;Face) matl = model.materials.add('gl_green') matl.color = Sketchup;;Color.new(0,250,154) matl.alpha =0.5 faces.each{|face| face.material = matl face.back_material = matl } end

He's actually using one of the standard color set.

As Dan says you can create and set materials in several ways.
face.material='red'
works because 'red
' is a standard 'color', and a material will be auto-created from that if it doesn't exist.
But
face.material='redex'
might fail because that isn't a standard color - that is unless it already exists in the model.materials, and it has that very name...It's best to try and separate materials and colors in your thought process...
Make the new materials up front and then specify them by name after that...
` mat=model.materials.add('redex')
mat.color='red'
mat.alpha=0.33later
face.material=mat
or
face.material='redex'`
etc -
Thank You again Dan and TIG ! . I understand an idea now.
