Hi,
I made a script to automate material assignation to the various nodes within the scene tree.
I am parsing the SceneTree with a for loop searching for group node type only and assigning a material to leaf nodes only (the ones without a child).
the node.setMaterial function is taking ages to assign a material to a node (sometimes several minutes) whereas it is almost immediate when doing the equivalent action within GUI by drag and dropping a material on an component/node.
Here is a portion of the code used :
for node in root.find(name = ref, types = lux.NODE_TYPE_GROUP):
print("#### Processing current node : " + str(node))
if ( len(node.getChildren()) > 0 ) :
print("No material assigned to " + str(node) + " : not a leaf ")
else :
asnMat = "Test_Material" #actually there is some logic here to determine the correct material
print("#### before node.setMaterial(asnMat) , asnmat=" + str(asnMat))
ti = current_milli_time() ;
node.setMaterial(asnMat)
deltati = current_milli_time() - ti
assigntime += deltati
print("#### after node.setMaterial(asnMat) , asnmat=" + str(asnMat) + " in " + str(deltati) + " ms")
print("assigned " + asnMat + " to " + str(node) + " -- idxM[" + mat+"] =" + str(idxM[mat]))
and here is a example of the execution logs for the above code

As you can see it takes from 32 s to 96 s for each node assignation. I can’t figure out what I am doing wrong. Is there any other way to assign material to nodes having better performances ?
Thank you in advance for your help.
