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

while node:
res.append(node)
for child in node.GetChildren():
res += flatten_tree(child)

return res

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.

The default python generator returns a parametric object (c4d.Ocube). So you have to convert it to a editable poly in the generator itself. So you don't need a cso in your script but in the generator when using parametric objects.
Python Generator
import c4d
#Welcome to the world of Python
def main():
c = c4d.BaseObject(c4d.Ocube)
return c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_CURRENTSTATETOOBJECT,list = [c],
bc = c4d.BaseContainer(),
mode = c4d.MODELINGCOMMANDMODE_ALL,
doc = doc,
flags = 0)[0]
script
import c4d
doc = c4d.documents.GetActiveDocument()
gen =doc.GetActiveObject()
print gen.GetCache()
SCALE_V
Doesn't change a thing. But i just discovered NEWLINE;
According to the documentation, my user data should be scaled when you provide them with the flags UNIT METER. Unfortunately, this does not work as hoped. Scaling using ObjectMode is running.
REAL GRIDDER_WIDTH { UNIT METER; MIN 0;}
REAL GRIDDER_HEIGHT { UNIT METER; MIN 0;}
To be honest. Just render the LatLong and then render the texture on a plane with the correct uv layout in the picture viewer or use Nuke or AE for it.
Double the render double the fun.
The Plugin has to be installed on all maschines - but your mentioned deadline so this should be no problem, just create a maintainance job for all clients and copy it via cmd or batch file.
Also it seems that call command isn't an option here at all:
Warning Must be called from the main thread only. Forbidden to call in expressions (Python generator, tag, XPresso node, etc.). See Threading Information.
Sorry for the missleading.
If you want to continue trying to kill the problem with python: you can run a python script as a monitor , waits until the scene loaded and than trigger some sort of buttonpressing in the mainthread.
But after all - rendering should be way faster than developing this.
Why not just rendering with a spherical cam or use a camrig for it?
Otherwise: Maybe creating a simple command plugin and run it via callCommand could work.
When displaying the remapping tab on a FIELDLIST the field ui is larger than the layout. At first i thought the issue was the lable of the field because i didn't manage it to create a line break like the falloff field on any effector but it makes no differences at all.
res:
GROUP {
FIELDLIST GRIDDER_FIELD { }
}
@s_bach said in Howto add a Field input to a python plugin:
FIELDLIST
works fine - i think i got an strange error before and trying CUSTOMFIELDLIST etc.
solved
i need the ressource syntax to add a field field to my interface.
I got a plugin which returns, base on its settings a mesh or a spline. If i create an instance from my plugin using only GetVirtualObjects the Instance of my spline doesn't work.
so is there a way to use both in one plugin?
