Find the model elements materials

[Gemini7]

Hi All,
What can be the fastest way to find the a model elements ( it's children )
materials. Is there a xsi build-in command for it ?

Thansks !

I don't know if exist a builtin command but maybe is fast enough iterate over the materials instead of model's children (there're usually more geometry objs than materials so...) and check if it's used.

Something like this...

Code: Select all

from sipyutils import si
si = si()


def GetMaterialOnModel(p_oModel):
    lChildren = p_oModel.FindChildren2("*").GetAsText()
    lMats = list()
    for oLib in si.ActiveProject.ActiveScene.MaterialLibraries:
        for oMat in oLib.Items:
            for oObj in oMat.UsedBy:
                if oObj.FullName in lChildren:
                    lMats.append(oMat)
    return lMats

for i in GetMaterialOnModel(si.Selection(0)):
    print i

Hope this help,
Cheers!

Thanks !
I thought something similar like that.
Maybe i will need a faster code than iterate trough so long..
You know there could be nested models and a lot of materials and
the time it requires can be very long.

Thank you again.
