最近常處理max或maya的FBX丟進來的場景，通常匯進來的FBX要在另外建一個sop做合併彙整，但必須是一個node對一個object merge來針對各自物件做不同碎裂，如果FBX裏面物件很多，合併起來是相當麻煩的事情，所以這種重複的作業還是寫一個script去處理比較適當。
hou.ui.setStatusMessage("Select source node", severity=hou.severityType.Message)
source = hou.ui.selectNode()
if source != None and source != "":
hou.ui.setStatusMessage("Select target node", severity=hou.severityType.Message)
target = hou.ui.selectNode()
if source == None or source == "" or target == None or target == "":
hou.ui.displayMessage("Invalid nodes", ("OK",), hou.severityType.Warning, title="Warning")
else:
s_node = hou.node(source)
t_node = hou.node(target)
import_list = []
create_list = []
for child in s_node.children():
if child.type().name() == "geo":
import_list.append(child.name())
for node in import_list:
m = t_node.createNode("object_merge")
create_list.append(m)
m.parm("objpath1").set(source + "/" + node)
m.parm("xformtype").set(1)
chk_merge = hou.ui.displayMessage("Merge all node?", ("Yes", "No"), hou.severityType.Message, title="Warning")
if chk_merge == 0:
merge = t_node.createNode("merge")
for node in create_list:
merge.setNextInput(node)
t_node.layoutChildren()
另外，FBX匯進來的物件，其物件材質會有兩種情況：如果是單一材質，材質會上在SOP上，如果是多重(multi-ID)材質，他會在SOP裡新增group跟material節點。假如一個FBX包含以上兩種，之後把整個FBX的物件合併，會發現前者的材質沒辦法帶到，因為該物件primitive的shop_materialpath屬性沒有東西，所以必須要針對該物件去寫上屬性，這種事情也是很常發現，故也寫了一個script。
hou.ui.setStatusMessage("Select FBX subnetwork", severity=hou.severityType.Message)
selectNode = hou.ui.selectNode()
if selectNode == None or selectNode == "":
hou.ui.displayMessage("Invalid node", ("OK",), hou.severityType.Warning, title="Warning")
else:
chk_clean = hou.ui.displayMessage("Clean material path?", ("Yes", "No"), hou.severityType.Message, title="Warning")
for node in selectNode.children():
if node.type().name() == "geo":
mpath = node.parm("shop_materialpath")
if mpath.eval() != "":
mat = node.path().replace(node.name(), mpath.eval()[3:])
geo_node = None
for child in node.children():
if child.isRenderFlagSet():
geo_node = child
break
mat_node = node.createNode("material")
mat_node.parm("shop_materialpath1").set(mat)
mat_node.setNextInput(geo_node)
mat_node.setRenderFlag(True)
mat_node.setDisplayFlag(True)
if chk_clean == 0:
mpath.set("")
