After taking a deep dive into the documentation again i figure out that im thinking way to complicated. I use the Cache provided by cinema and write a custom check around it. This avoid using a cached mesh in a baseContainer and also removing a cinema4d breaking memoryleak in my plugin i just found.
So thank you.
This is the GVO from another plugin which works flawless. The only difference is that i didn't use an input object.
def GetVirtualObjects(self, op, hh):
if not op[c4d.ID_BASEOBJECT_GENERATOR_FLAG]: return None
if op[res.GRIDDER_OUTPUT] == 0:
if self.CacheCheck(op, op.GetDocument()) is True:
preReturn = op[res.GRIDDER_CACHE].GetData(1005)
return preReturn
return self.Gridder(op)
return None
meshCache = op.GetClone()
bc = c4d.BaseContainer()
bc.SetData(1001, self.HelperGetOptions(op))
bc.SetData(1002, self.CacheShader(op, doc)[0])
bc.SetData(1003, self.CacheField(op, doc))
if doc != None:
bc.SetData(1004, doc.GetTime().GetFrame(doc.GetFps()))
bc.SetData(1005, meshCache)
op[res.GRIDDER_CACHE] = bc
c4d.StatusClear()
On the other hand: I have no idea how to serialize a polygon object with uvs, vertex maps and phongtag. Also seems HyperFile a little bit over the top to store something temporary. MemoryFileStruct() could work but I need to store the byteseq as well...
GetAndCheckHierarchyClone works but it has the disadvantage of refreshing during viewport changes, so I need to use my own dirtycheck.
I think I am doing something fundamental wrong there
my generator plugin takes the first mesh child object and modify it. than it stores the current values into a bc and return the mesh to the scene unfortunally i can't get acces to my cache mesh via bc via
clone = op[res.REDUCER_CACHE].GetData(1005)

What i do:
Version affected : 20 & 21 can't test 22 because i didn't have an developer version and no active subscription.
okay
so it might be an easier solution to just iterate over all childs from my generator plugin and check for the first BaseMesh.
i got a plugin with a field input. if i create a new field object, cinema automatic create its as a child. is there a way to force new field objects spawns nexts to my plugin not under ?
If you delete a field object in the object manager, GetCount() does not change. Worse if you repeat the whole thing, the value even increases.
The issue also apply to HasContent()
workaround / seems to work in my usecase
def CheckFieldHealth (self,doc,field):
if field == None: return False

""" Returns all field layers that are referenced in a field list.

def flatten_tree(node):
""" Listifies a GeListNode tree.

res = []
while node:
res.append(node)
for child in node.GetChildren():
res += flatten_tree(child)
node = node.GetNext()
return res
# get the GeListHead for the FieldList
root = field.GetLayersRoot()
if root is None:
return []
# Get the first node under the GeListHead
first = root.GetFirst()
if first is None:
return []
# traverse the graph
return flatten_tree(first)
error = 0
for f in get_field_layers(field):
if f.GetName() != None and f.GetLinkedObject(doc) == None and f[c4d.DESC_NAME]== None:
error += 1
if error == field.GetCount(): return False
return True
It fits in the UI - but if i switch to remapping the width increase slighty.
