[Plugin] Remove group materials, leave geometry material

thomthom

Matthieu,

You are the man! If you can produce a ruby script which removes group materials and applies them to the default geometry you will save me about 3 day's work on this model alone! I'm trying to update my portfolio so this would be of enormous benefit to me as I've got lots to do and very little time to do it.

somewhat off topic, but: where did you get hold of the ground texture?

watkins

Could someone explain exactly what this script does, and what are the benefits? It would help the technically challenged, like myself.

Kind regards,
Bob

It makes sure that no materials are applied to groups and components. It will either remove the materials of groups and components or transfer them to the geometry.
For users of V-Ray for SketchUp it has the benefit of faster parsing time and more reliable outcome as VfSU struggles to get correct data for groups and components with materials applied to them.

Thank you Thomas.

Bob

i havent tried your plugin just like to thank you for giving this solution

i already stop using the latest vray bec. of some issues but if this plugin will work wow thank you so much

thomthom

Matt; You could benefit from using the extra speedboost argument for the start_operation method which was introduced in SU7.

Matt666

Yep! First code post updated! Thank you Thomthom...

Didier Bur

Hi Matt,
Is this version only for v7 or does it run under v6 too ?

Matt666

Hi Didier!
This update works with both versions.

if Sketchup.version[0,1].to_i >= 7
  model.start_operation("Remove comp & group materials",true)
else
  model.start_operation("Remove comp & group materials")
end

Thank you for the remark

Didier Bur

Merci,
C'était pour savoir comment l'indexer sur mon site.

I have a suggestion for an improvement. An option to make components painted with different materials into unique components.

Matt666

Hi thomthom!
Sorry for the delay! Great idea! O've updated the code.
I've tested it veeery quickly....
The plugin post is up-to-date.

Thank you Jackson

Amazing work Matthieu!

Sorry Matthieu, I just ran a test and this isn't working, or at least it's not working at all as I would like. It doesn't create distinct components according to colour as ThomThom suggested- after running it on 3 identical car components which I'd painted different colours it just turned them all blue and they are still intances of the same component. I don't understand the logic behind the new colour choice for default either (personally I don't like ruby scripts to use their own material libraries, as I keep very strict control over my materials libraries, but that's another story). Surely this feature overrides the whole point of the original script i.e. that it replaces the default material applied to geometry within groups and components with the material which has been applied to the groups or component. Now all the geometry with default material applied turns a new global colour, which make the script useless for V-Ray users.

Sorry for the criticism, hopefully you understand it is intended strictly constructively! I am still your number one fan!

You can use this new script as the old... Just select Yes, and default. And it will do the same thing! Or I'm completely wrong

In fact I didn't understand Thomthom's request
Here, the update can replace parent material to desired colour. Or replace the default material when you choose No... If you don't understand, tell me... I have a poor english...

Thomthom's request is agood idea... I will see what I can do!

Jackson

Matthieu,

Still not working properly I'm afraid. Despite selecting "Yes" and "Default" 3 differently painted cars all turned red. Can you reattach the original (i.e. pre 17th March) ruby script while you're fixing the new one please? I stupidly overwrote it when I installed your new version and I'll need the old fully-functioning one for work tomorrow!

Thanks again for all your hard work!

Matt666

This is normal your 3 differently painted cars all turned red. I didn't understand thomthom's request (my poor english )... The last one works like the precedent: It puts comp material on geometry, but it doesn't make different color component unique! No need to re-attach the original.
And I also lost this one !! However I'm sure this last update can do what precedent version was able to!
A future version will be able to do what thomthom want...

Jackson

Ahh, I see... so I can continue using the current ruby script, just as long as I don't have identical components with different materials applied to them.

One further suggestion for the next version though (I bet you wish you'd never started now!)- the Yes/No selection should be set to "Yes" as default or just set up as an "OK?" warning message as it was before, as it's rather irritating to have to change it every time you run the script (which in my case is many times daily). If the end user didn't want to apply the C-G materials to the geometry they wouldn't have chosen to run the script! I think the warning is sensible though so people know they are applying a permanent change to their entire skp file.

thomthom

Did I cause all this? ooops....

p.s. Matt
Inregards to if Sketchup.version[0,1].to_i >= 7. This will break when SU hits version 10. (A bit far of, I know) But instead you can do if Sketchup.version.split('.')[0].to_i >= 7 which is future safe.
