I love this plugin, thanks.
(it saved my life ^^)

Sir let me know how to install it.. do i simply paste it sketchup folder?? dont have exact idea.. thank you

Find and read the several tutorials on how to install various kinds of Plugins.
http://sketchucation.com/resources/tutorials/37-beginner/108-installing-sketchup-plugins
There are other useful guides in that section too...

In synopsis...
A simple .rb [like this one] just needs to be put into the Plugins folder and SketchUp restarted.
Then you use it as instructed...
You will need to set your Plugins folder's security permissions to FULL [Properties>Security>Edit>FULL>Apply/OK] - by default Windows sets restricted permissions [for everyone, including admins] for all such folders with the Program Files folder.

FYI...
ZIPs need the files/subfolders extracting and moving into the folder keeping them in the same relative relationships...
RBZs need installing using >=v8 Preferences>Extensions>Install... button - if you don't have that button update your v8 to the newest release, OR get v2013?
You can rename a RBZ with a final .ZIP and treat it like a ZIP archive - IF you are a masochist !

OR even easier...
Nearly all of the Plugins with threads on SketchUcation are available in the SketchUcation PluginStore - open its page through the Resources menu above... Get the RBZ and manually install it...
You can even install the SketchUcation Plugin Store Toolset from there [or from its own dedicated link] - this displays all of the available Plugins in a dialog within SketchUp and AutoInstalls them for you without you ever having to worry about where the Plugins folder is etc... [provided of course that you have set permissions to FULL!]

A little Question

When you apply a Texture to the "external" faces of a component the instances are not changed!

When you apply a Texture "inside" a component (or an instance) all faces of Components are changed!

How automate the process when you Pick the texture of the "external" face of the component for have the second result ?

[mprose7]

Is there chance to add auto function which would change all 'mat1', 'mat2', 'mat3' to 'mat', since sketchup automaticly add number to 'mat' if i import models with identical named mats but changed color. example: i copy window from other model, it has material named glass, but it is a bit more blue than glass from scene and now i have material glass and glass1 in scene...

[TIG]

If you run this code snippet in the Ruby Console, then all matching materials are equalized 'by name'.
So in the example patt='glass' - it then resets the RGBA/texture of 'glass1', 'glass2' etc.
Then you can use my MaterialConsolidator plugin to compact all of the model's materials which have exact matching RGBA/texture into just one material...
http://sketchucation.com/pluginstore?pln=materialconsolidator

# !!! Use with care - all materials starting with 'patt' take its color/transparency/texture/size etc.
patt='glass' #change as desired
model=Sketchup.active_model
mats=model.materials
mat=mats[patt]
unless mat; puts "NO material named '#{patt}'"; return nil; end
col=mat.color
r=col.red
g=col.green
b=col.blue
c=Sketchup;;Color.new(r,g,b)
a=mat.alpha
t=mat.texture
model.start_operation('mat_equalizer',true)
if t; f=File.join(Sketchup.temp_dir,File.basename(t.filename)); t.write(f); h=t.height;w=t.width ;end
mats.each{|m|p m.name; next unless m.name=~/^#{patt}/; m.color=c;m.alpha=a; if t; m.texture=f; m.texture.size=[w,h]; end }
model.commit_operation
#use material consolidator to get just one material after this...   

[mprose7]

Is there any option to automate this process - can script automaticaly search materials like glass, glass1, glass2; chrome, chrome1, plastic, plastic1, etc
And then consolidate with consolidate plugin??

It has been a while since the last posting and SU2022 is the current version.

Any reason this should not work or is there anything in the current ruby version that could improve the performance of the plugin?

I have found that it does not seem to work properly if the selection of objects contains copies of groups or components. This behavior occurred in tests with both SU2017 and SU2022.

Please see the attached example which I used for testing.

[TIG]

Copies of groups are pretty much like copies of component-instances, BUT if you edit [open] a copy of a group then SketchUp always automatically makes it unique [even if you do nothing in the edit-context] - this is unlike a component-edit operation... with components you must choose to 'make unique' which will then limit any changes you make to only that new definition's instances' entities.
Any materials edited inside an edit-context are shown in all of the instances of that component - so if you only want to change one of them you must choose 'make unique' from that instance's context-menu before choosing to edit it...
This is unlike if you add materials to the 'container' itself [i.e. group or component-instance] then these are only applied to just those specific 'containers', however, unlike textured materials on faces, you cannot 'adjust' textured materials on 'containers' using the native context-menu item. But solid colors work fine... This limits the usefulness of this approach as with roof tiles or sidings etc you probably want to adjust the textures location of orientation etc...

[JClements]

So why do you think this characteristic of copied groups was implemented by SU in the 1st place? What is the benefit for modeling process? This behavior feels more like a bug rather than a benefit.

Is there anything that can be done in ruby to simulate the process opening and editing groups so that the copies are “unique” … circumventing the manual process?

[TIG]

'Make unique' is accessible through the API thus...

This works on groups in each separate entities context...

model = Sketchup.active_model
model.start_operation('Uniquify Groups', true)
model.active_entities.grep(Sketchup;;Group).each{|g| g.definition.instances.length > 1}.each{|g| g.make_unique }
model.commit_operation

To process all groups [inside every context or nested inside components or other groups]...

model = Sketchup.active_model
model.start_operation('Uniquify All Groups', true)
model.definitions.each{|d| d.group? && d.instances.length > 1 }.each{|g| g.instances.each{|g| g.make_unique } }
model.commit_operation

Copy/paste code into the Ruby Console and press enter...
It's one-step undo-able through the Edit menu.

[JClements]

Thank ,you TiG that worked!

Any chance of incorporating the code into GlobalMaterialChange2.rbz ?

And/or a separate Plugin for displaying an option (such as "GroupCopy UnInstanting") in the Context Menu that would appear if objects are selected?
It come in handy for other issues that might happen with copied groups.

P.S.
Your previous post regarding editing a group, gave me an idea of how to make it easier to manually open multiple occurrences of groups containing materials.

I gave all groups containing materials an Instant Name that included the text "....(with material)". Then, by opening the Outliner, and searching for "(with material)" and double-clicking on each find to open and close the group. It was a fairy quick process compared to opening each group in the modeling window.

If a group's instant is properly named then all is good, BUT it takes discipline when creating groups in the first place.
