this is common Samir, I always do this "test a lot , get a whole picture, and miss a small detail".
glad that it helped

Hi,
sorry guys, gotta steal your time once again as I now know why I used the "normal" clones in the first place (sorry, didn't recall before but only today when I indeed tried this). I am in a SceneHook Execute() function and GetCache as well as GetDeformCache always return a nullptr.
SendModellingCommand only seems to return the final polygonal hierarchy. So is there a way to access the virtual cache from here anyhow?
Maybe I need to clone the doc somehow, let the cache be rebuilt (which would probably impose a performance penalty if dynamics need to be recalculated for the frame of retrieval?) and read the cache then? I'd rather not because this would also include my own dynamic calculations to be redone which is really no option (it could be hours of simulation time for previous frames...worst case scenario).
Maybe there is a way to rebuilt the caches?
Thanks again!

Hello,
what exactly are you doing in you SceneHook and when? In AddToExecution() you can define when in the execution pipeline your scene hook is called.
Best wishes,

Hi,
what exactly do you mean by "what exactly are you doing"?
I am grabbing an object from the OM (my own object plugin) and reading out an object (in this case the Cloner but it doesn't matter what object, it's always nullptr) from a link field of it. Then trying to get the cache.
obj = my_op->GetDataInstance()->GetObjectLink(ID);
obj->GetCache()execution pipeline priority is EXECUTIONPRIORITY_DYNAMICS (which I want to be in btw.)

I assume caches are not yet built (but will be only in EXECUTIONPRIORITY_GENERATORS) so I guess I need pre-built caches?
Can I use the Hierarchy class for this purpose?

Ok, the hierarchy class seems to go through all objects in the scene. This seems a bit overload. I just need the single cloner object (and its children) to build its cache I guess.

Hello,
I just tried to access the cache of a MoGraph cloner in a SceneHook::Execute() with EXECUTIONPRIORITY_DYNAMICS and it seems to work fine in R17. Does the problem also happen for you with R17?
Best wishes,

Thanks, I will have to try that!

You are right, trying it with a minimal sample in r17 works! Ok, then it must be an implementation problem on my side for the r16 version.
Cheers and finally solved!

@Katachi: Are you able to make changes to the cache that are actually reflected with nested cloners?
I never could get it to work (regarding the topic that you have linked). -

Not directly. What I am doing is using an additional Effector that reports back any changes to the clones (which means tracking the mograph objects, their deletion etc on my own). This works quite alright though of course that's not optimal.
