How do I get the cache of a cloner in an ObjectData Plugin

ThomasB

Hi, sorry for this as always dumb question.

I was trying to get the Cache of a cloner object in the GetVirtualObjects(self, op, hh) method.
First I tried it in the python generator, there was already a cloner in the scene and in the python generator I returned the cache so to say, but this approach doesn´t work out in an object plugin.
Even if I create a temp_doc. The returned cache is always None.
But converting the cloner with a ModelingCommand is not the best way, if the cloner produces for instance a million clones.

This method works in a python generator when the clone is already in the scene

cloner = op.GetDown()
return cloner.GetCache().GetClone()

But creating a cloner and returning its cache doesn`t work.

cloner = c4d.BaseObject(1018544)
c4d.BaseObject(c4d.Ocube).InsertUnder(cloner)
return cloner.GetCache().GetClone()

Is there a way to get the cache in a plugin?
Sweep, Extrude, other Generators, Deformers and parametric objects work perfectly.

Hey @ThomasB,

thank you for reaching out to us. First of all, there are no dumb questions Caches must be built, and a newly allocated object has no cache. Please have a look at geometry_caches_s26.py for an introduction into caches, including how to build them.

Cheers,
Ferdinand

@ferdinand
oh man thanks I forgot this

BaseDocument.ExecutePasses(bt=None, animation=False, expressions=False, caches=True, flags=c4d.BUILDFLAGS_NONE)

I tried that before but it seems I have set the caches parameter wrong.
Thank you very much....
