I will check this out...
And yes... maybe I am confused on what is going on ...
The issue I am having is that is I searching for all the 'mesh'
objects in the scene, once I find one, I look for it's transform node,
and take the tx,ty,tz data from that and save that info to a file.
The problem is that when they are grouped and instanced, I am not
getting the info that tells me that I have an instanced node and that
I need to look for more transform data. Because I get an entry in my
txt file for all the nodes in the scene, but O am getting duplicate
transform data. So my thought was to take the world trans info from
the instanced group and add that to the transform data that I have
collected. But I am hoping there is a much better way of doing this.
Here is some of the code that I had before.
from pymel import * # safe to import into main namespace
def exportGeo(objFolderPath):
obj = "OBJexport"
for x in ls(type='mesh'): #find the mesh's in the scene
print x
select(x, add=1) #select them
#for mesh in ls(sl=1):
print x
objTransName = []
objTransName = listRelatives(x, ap=1) # build a list of their
parents. Ideally the transform nodes
if len(objTransName)>1: #test to see if there is more that one
Transform node for the mesh (instance)
select(cl=1)
for instance in objTransName:
select(instance) #select transform node
objTransName = str(instance)
print objTransName
objTransName = re.sub("[\[\]\(\)']", "", objTransName)
#strip out bad chars
print objTransName
objFileName = os.path.join(objFolderPath, "%s" % (objTransName))
exportSelected(objFileName, pr = 1, typ = obj, es = 1,
op="groups=1;ptgroups=1;materials=1;smoothing=1;normals=1")
else:
objTransName = str(objTransName)
objTransName = re.sub("[\[\]\(\)']", "", objTransName)
objTransName = re.sub("Transform", "", objTransName)
#print objTransName
objFileName = os.path.join(objFolderPath, "%s" % (objTransName))
exportSelected(objFileName, pr = 1, typ = obj, es = 1,
op="groups=1;ptgroups=1;materials=1;smoothing=1;normals=1")
select(cl=1)
exportGeo(objFolderPath)
print "Exit"
-------
I have stripped a bit out there... but ideally that helps explain the
issue I a dealing with. I am assuming that this is something very
stupid and is dealt with all the time, I am just not very fammiliar
with all of this, and am looking for the best way to get all this
info. I also have locators that I am going to be doing this for as
well. This is what sent me down the path for looking into the
isInstanced() function.
Thank you!
Sincerely,
Justin
