Is it possible to change just the material of the picked face?

Can't you just paint it ??

The beauty of this tool - You don't have to open a component to change the material of the faces.
But it changes all the material in the whole model - not just the face You click on.

BUT your question was to change the material of the picked face !
You mean to change the material of the picked face INSIDE THE GROUP/INSTANCE !
It couldbe done... but I must leave it to others......

dedmin

Yes, inside the group or component. And only of that picked fase.

How do you install this plugin

thomthom

Open the zip file and drop the .rb file and the folder with it into the Plugins folder where SketchUp is installed.

It would be possible to create a function swap some materials? Something like this:
Imagine a blue box and a red ball. We play the plugin, we click on the box and after the ball, and the colors are reversed. It would be interesting too, if it were possible to exchange materials not in the whole scene, but only on selected objects. Thanks for this fantastic tool.

Is there any way we can use this plugin to replace a specific material [.skm]..that has been used in the model with vray materials [i.e. .vismats]...??

Use V-Ray's material editor. Right click a material and Import

This sort of ties in with the current thread:

As I can see, this plugin replaces a material globally in entire model. It would be awesome to have option to replace material on a specific object only.
Will you take into consideration my suggestion?
Thank you.

You probably need http://forums.sketchucation.com/viewtopic.php?p=63629#p63629 [my olde Global_Material_Replacer.rb tool] - it is dialog driven to choose the material to go and material to use - including 'All' and 'Default-front/back'. It swaps materials in the entire model's active_entities collection, OR IF there's a selection on selected objects... It works inside 'containers'...

As I could see, thomthom's plugin keeps UV mapping, when replacing materials, which is cool . Does yours keeps UV ?
When I use paint bucket tool to change the material on some object, the UV is reset.

Use the Entity Info to replace materials - then the UV is preserved.

Thanks! I never used it.

Like with Entity Info... my tool swaps the material but keeps the UV-mapping - so any rotated or scales/skewed textures stay unchanged, but the material uses a different image-file...

Will this affect Twilight metadata? If I change a "wood" material with a "metal" material, both with textures... will it render as "metal", or just the image is changed and uses metadata from initially "wood" ?

You could always try it yourself...
A Twilight material is associated with a SKP material.
If you have a gray RGB material in your SKP you can tell Twilight to substitute it with a silver metal - shiny/textured/etc.
If you have a buff RGB material in your SKP you can tell Twilight to substitute it with a golden metal - shiny/textured/etc.
If you swap around materials in your SKP it'll be reflected in corresponding changes in the next Twilight render.
How would changing a face's material in the SKP NOT affect the Twilight render? AND how might it affect the Twilight material - which is associated on a one-to-one relationship - gray=silver, buff=golden etc?? It only swaps around SKP materials by name it doesn't redefine them or rename them. I'm not sure what happens if you swap the names of materials over in your SKP - presumably if you said in the SKP material Browser gray=>gray1 and buff=>gray and gray1=>buff, then if Twilight uses a material-name look up table for how to render each of its materials based the SKP's current material-names then it would indeed swap what was silver with golden and vice versa... Perhaps useful on occasion, but not the point of this current discussion or thread.

So to recap, swapping a face's SKP material gives the face that other SKP material, the face's material's UV-mapping comes from the face itself; whatever 'correspondence' Twilight a material has with the SKP material is kept intact and it renders accordingly...
