I'm only able to get a cache from a deformed Point/Polygon Object.

When and where are you trying to obtain the cache?
I was able to get and use the cache of an object in the Editor, but it does not seem to possible while rendering.. (in a PyTag, for example)

Nik, set Priority late Generators, didn't we agree on that before

The question still remains, can/do a -undeformed- point/polygon Object ever have a Cache?

Testbench for use in a Py Expression Tag set to Priority late Generators.
Try on a undeformed point object, deformed point object and all kinds of generators,
with and without deformers.

# In Py expression, set Priority to late Generators   
import c4d   
def main() :   
    obj = op.GetObject()   
    try:   
        if obj.GetCache() and not obj.GetCache().GetDeformCache() :   
            print 'Generator Cache' #But nothing from a point object   
    except: pass   
          
    if obj.GetDeformCache() :   
        print 'Point Object DeformCache'   
        return True   
    try:   
        if obj.GetCache().GetDeformCache() :   
            print 'Generator DeformCache'   
    except:   
        print 'No Cache'

Oh man, you're right, Lennart. Ha! Really forgot about that. Thank you, once again. Tongue

Guess I wasn't really concentrated on my previous answer, sorry. To come back to your original question:
_
> In Py, is a undeformed Point/Polygon Object supposed to generate a Cache? _
No, I'm very very very sure it is not. What object do you expect? It could actually only return itself on ~.GetCache() , but that would go on recursively, then. It only needs to create a new polygon-object internally as it differs from it's state before deformation, but without changes, there is no reason to create a new object that is used as "cache". (Was that actually clear? I'm a little tired, lol..)

I'm pretty sure as well, based on that test bench example,
but all I' asking is Yannick to get those germans out of the pool
at Max-Planck-Strasse and get a yes or no (Joke!).
A no is fine, so I then can make my own cache routine.

The reason is for the on going woes making Generator Plugins
dependent on external objects that are not children of the Generator Object.

To the best of my knowledge, the routines available are Hierarchyhelp
for Point object Generators and CheckDirty for Spline Object Generators.
As undeformed Point objects are not returning a Cache, both methods fails
and need, as it looks, a separate routine.
I'm fine with that if I know it has to be done/spend time on.
