Hi,how can I access the subdivided mesh of an object that is in a hypernurbs object within GetVirtualObjects()?
It seems all the caches are not yet built in GetVirtualObjects and therefore the SDSObject always returns NULL. So, what´s the possible approaches to safely get the subdivided mesh?
Thank you!

One week later. Helloooo? Anybody there? Support? Should be a fairly easy question since HN is in C4D for...how many years?
Please I want to know! -

Did you try the GetHierachyClone and GetAndCheckHierachyClone functions? If you have to use the CurrentStateToObject function make sure to clone the objects to a new dummy document and call CurrentStateToObject for this dummy document.
cheers,

nono, you misunderstood. I want the subdivided mesh of a polygonobject that is in a HyperNurbs! I don´t want the user to input the hypernurbsed mesh because I need the indices of the unsubdivided mesh, but the surface of the subdivided mesh.
Just as Hair is doing it. Input the polygonobject in a HN and hair puts the guides on the hypernurbsed mesh. So there must be a way to access the Hypernurbsed mesh and get information from it, so that you can work with the corresponding vertices, edges etc.

From what I remember David saying, he had no elegant way of getting the mesh. As you've noticed, if the caches are not built yet, that is not a possible way to access the data. I'm afraid I don't know the details of how he did it.
On the other hand, I think I don't really understand what you mean. Just like Matthias, I thought that you could simply use GetAndCheckHierachyClone() or in the worst case CurrentStateToObject? Why doesn't this work? -

Performance.
It would require me to convert both the polygonobject with CurrentStateToObject (to get it´s deformed state too, which is NOT returned with GetHierarchyClone()!) and then also the HyperNurbs Mesh (as also here GetHierarchyClone() does not return the deformed mesh).Depending on the input object, this can take pretty long. Ok, this would somehow be acceptable, but this wouldn´t help me that much, as I have no relational information about which edge, poly and point is the corresponding edge,poly and point of the subdivided object.
And I need both meshes. The vertices of the low-poly object and the HN mesh for the surface and relational information.
Is this comprehensible. I am not sure.
I already thought about calculating the vertices normals and get the nearest point along the reverted normal. But that probably won´t work for all meshes and already sounds unsafe.

I think this is impossible to do without initiating the calculation yourself, since if the caches are not built that means the calculation hasn't been done yet. Some clever caching could be adopted for performance, I guess. Please chime in if you have managed to get this going in any other way, but I can't think of any other way.

ok, thanks Mikael. I´ll see what I can do about it.
