[Plugin] Remove group materials, leave geometry material

Done - I hope you don't mind Jackson.

Merci beaucoup Matthieu (and Csaba for editing the title)!
I was wondering, is there a way you can think of which would do what your script does (delete group materials), but rather than just leaving the default material in it's place it would actually apply the group material to the default geometry itself? One workaround would be to explode and then regroup all groups one-by-one, but the catch is components- their attributes are just too valuable to lose by converting them into groups.
Thanks again, you've already saved me DAYS of very, very tedious work.
p.s. I have one suggestion for your script above, maybe it would be better if it was named "Remove_CG_Mat" as ""Delete_CG_Mat" sounds like it would delete/purge those materials from the actual skp file, which might make people a little reluctant to use it.
-
I want to extend my thanks as well. This will be an invaluable ruby to help speed up processing/parsing times for Vray!

Jacksons suggestion for the script to apply the material of the group to all geometry with default colour within the group before removing the group-colour is a fantastic idea.
Imagine you have a rather complex group, several faces are painted with different materials, the rest is not coloured yet. all you have to do now is apply the colour for the rest of the faces to the group and rund Matthieu's script. that is much faster, than selecting all the untextured faces manually...
of course it could be quite tricky if you have nested groups within the painted group. then the script had to go down all the hierarchy into the lowest groups to paint the faces. of course it had to work from the 'inside' to the 'outside', so that the colour on the outermost group has lowest priority...
-
My earlier 'GlobalMaterialChange' script works on a selection: so by using Didier's filter tools you could just have what you want selected [e.g. Groups] and 'change all' materials in that to <default>. It can 'mine' into a group or component to change things within it too...

Or am I missing something ? -
while on the subject of helping out vray, vray SR1 creates vray materials of all materials in the scene even the materials on lines (multi-coloured from CAD imports) could there also be a script to remove all materials from lines? that way vray wouldnt create any unnecessary materials

Hi all!
Sorry for the delay, I was in London last week...So:

Yes, it's possible. I will add a message box to the script.@unknownuser said:

Ok!@unknownuser said:

Yes, it's possible. Vray uses attributes to record all object material. You just want to remove it.I just need for time to do that

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.
-
To Free Agent, can you share an example with Vray line material, please ?
Thank you ! -
Matthieu,
Free Agent means SUs own materials on lines, there's no separate VRay materials- it just creates/links it's own materials from those of SU. A standard skp model will contain the line materials Free Agent is describing.
Free Agent,
When SU imports dwgs and adds materials to lines (i.e. layer materials from Autocad) just delete those materials either by right-clicking on them in SU's material editor or (if there's lots of them) by opening the imported dwg group, switch to wireframe view, select all, paint with the default SU material and then purge the file. This will also delete all unnecessary VfSU materials.
-
Ok, but I will wait for Free agent answer to do smt
!
I've updated post of the script with demanded improvments... I did'nt really test it...
-
Matthieu,
I just ran it on this fairly simple model, but unfortunately it has applied the wrong materials to the groups, see before and after image below. I thought it might be applying materials from higher up the group heirarchy, but that doesn't seem to be the case. Any idea what's going wrong? I can send you the skp file if you like.
-
Can you send me the skp, please?
Thank you !
Sorry, I don't have a lot of time to test...

LOL, definitely no need to apologise!

Hi Jackson !
I don't forget your demand !!
I have no time to do smt now, and I have a problem of "Hierarchy" in your drawing example... So it's quite difficult !
But I think I will show smt in a few days..See you soon !
-
Matthieu,
No worries, your original "Remove CG Materials" script has already saved me about 20 hour's work so I'm pretty happy already!
Best regards,
Jackson -
We loosed some posts here
So, script's post has been updated... Not tested enough, but I'm a few confident !
Now all Comp/Groups materials are transfered to geometry if you want.
-
Seems to work perfectly Matthieu! I just ran it with the test file I sent you and it reassigned all the materials in just a few seconds. This is such a valuable little tool for "VRay for SU" users, I will spread the good word (and your name) over at the ASGvis forums.
Many many thanks for creating this little gem, MERCI BEAUCOUP!
Jackson -
You're welcome, Jackson ! Glad to help you ! -
thanks so much, Matthieu!
only one minor thing still: while all the materials are applied to faces and the material of the outer group is changed to default, nested groups still keep their assigned material. that is not very important, because the face's textures are the dominant ones. but to be perfectly accurate, it would be great if the plugin could assign the default material to nested groups too.
one positive side effect I experienced is, that your plugin coloures front and back faces. that is really good!
