[Plugin] Material Replacer

derei

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

Thanks! I never used it.

[TIG] Does yours keeps UV ?
When I use paint bucket tool to change the material on some object, the UV is reset.
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...

Hi thomthom,
Love this plugin by the way. Is it possible to have the material name display whenever using the eyedropper tool and not just when running your ruby script. Having the name of the material display is SOOOO handy and I'd love it if the eyedropper always displayed the material name. Is this possible? I work on mac so currently trying to work out what material is what is pretty tricky due to the absence of a list view in the material browser. Also would it be possible to move the 'material replacer' to a context menu so you could access if using a right click rather than going to the drop down menus?
Fantastic tool tho - thanks!
Sam

I can't modify the native SketchUp tools I'm afraid.

As for context menu, I could, but then someone would ask me to reverse it. But I'll see if I can send you a modified version.

samyell77

Would really appreciate that - thanks!

Hey Thomthom - don't worry about sending the revised ruby. I hadn't realised that I can invoke plugins using key commands so have set up a keyboard short cut to your material replacer now. Thanks

Does this work with SketchUp 8 Pro? I copied the unzipped files into the SketchUp Ruby folder but it is not showing up in the Plugins menu in Sketchup...

TIG

You don't see it there because it's not in the 'Plugins' menu!
It's in the 'Tools' menu - as 'Material Replacer'...

Thanks for a great time saver.

thanks Thomas, I use this plugin a lot!

Thank you very much for this extremely useful tool! I Just tried it out and it works smoothly and without any trouble! Thank you!

Hi, great simple little tool works perfectly, except the material being replaced, did not inherit the same scale of the texture. Any ideas?
thanks

LesZautres

This plug-in does exactly what I expected through a really nicely made UI!
Many thanks!

I think this plugin can be updated to make this function possible.
More details:
window frames with different sizes say 4'x3', 2'x3, 5'x2' are present which has same wooden texture(teak). Using this plugin if 4'x3' selected as source material then all other group/model with same dimension(ultimately volume) can be replaced with other material(oak) and other frames should remains unchanged.

Hi Thom,

with a little guide from TIG here, I manage to update this plugin.

I have no knowledge about ruby , not even a basic grammer , but as I am familiar with other languages like php and C++ , I just gone through the some ruby resources and made this modification.
Some minor changes is required as when trying to replace the default material , it is replacing whole model.

I am attaching both modified code and skp test file, hope you rectify this minor bug .

default material change bug using Material Replacer(Mod)

Thanks. I've added an issue in the BitBucket repo to remind me to merge this: https://bitbucket.org/thomthom/material-replacer/issue/1/merge-user-fix

I have been exploring the Thea for Sketchup latest build on my Mac at work using SketchupPro2014 and was just playing around with the Thea Materials and Material Replacer this morning and think I have run into a serious problem.

I had just added some of the default materials from the Thea library to the sketchup material library and had applied them to some of the components I had been working with earlier.

I had applied the materials to the whole components instead of the faces of the components on some, while going inside of the components and adding the materials directly to the faces of the objects on others.

I then drew a rectangular plane next to the models to pull the default material color from.

Next I successfully used the material replacer to replace the materials applied to the components as a whole from their Thea Material (which was one of the default wood materials) back to the default white/blue sketchup material from the rectangular plane I was pulling from.

However when I attempted to replace the materials inside of the components where the faces had been directly painted (using the example 01.mat.thea inside the displacement folder in the Thea Material Library) sketchup hung up.

I force quit the program expecting to simply reopen the file, or at least even an earlier version of the file, but to no avail. All I get now when trying to open the file is this error message

I even used Time Machine, which pulled versions of the files created earlier... same problem... Could you please shed some light as to how this problem could have occurred, or how I might be able to recover my files?

-Thanks

Can you upload or PM the file in question?
Does the backup file work? (the one with the tilde)
