Hi, does anyone know how to get the object's UVsets data in PyMaxwell4? I can only get the count of each object.

from pymaxwell4 import *

def test():
file = "C:/Users/twong/Desktop/test.mxs"
scene = Cmaxwell(mwcallback)
scene.readMXS(file)
it = CmaxwellObjectIterator()
obj = it.first(scene)
while not obj.isNull():
obj_Name = obj.getName()[0]
print('\nobj_Name:', obj_Name)
if obj.isInstance()[0] == 0: # 0=Object, 1=Instance.
obj_UVSets = obj.getChannelsUVWCount()
for u in range(obj_UVSets[0]):
obj_UVChannelId = obj.getUVWChannelId(u)
print('obj_UVChannelId:', obj_UVChannelId)
obj = it.next()

test()

From the documentation that comes with the installation (sdk/doc), there's a function:

byte getUVWChannelProperties (dword iChannel, byte &projType, bool &customProj, Cbase &projectorBase, real &startLatitude, real &endLatitude, real &startLongitude, real &endLongitude, real &startAngle, real &endAngle, bool &mirrorBackFaces) const

It should exist the same method on python.

I still can't get it, I tried "obj.getUVWChannelProperties(0)", it return error = Invalid object to get UVW channels properties.
Could you give me more hints?

It seems that it only work with user defined data. Let me check this next week with the dev that made pymaxwell.

CmaxwellObject.getUVWChannelProperties is meant for procedural geometry objects, which UVs were generated by CmaxwellObject.generateCustomUVW.

UV projection parameters used to generate UVs in Studio, in the way you show in the screenshot, are saved as "Maxwell Studio custom data" in the MXS, so they cannot be retrieved from the public SDK. It is opaque data that only Maxwell Studio knows how to handle.

I see, thank you for all of your help.
