@zipit That bad? Gee... this one is gonna break my brain! Thanks!!!
Nah, DescIDs are not really well explained in the Python SDK (actually they are not explained at all, just documented). So it is understandable to struggle a bit with them. A good reading tip is always the C++ SDK, in this case the DescID Manual which will hopefully make things a bit more understandable. One thing worth mentioning is also – with which you seem to struggle – the way user data DescIDs are build. To access a the x component of a of a non user data description element of the type c4d.Vector you would do this
# Build a descid for my_vector as a whole
descid_my_vector = c4d.DescID(c4d.DescLevel(c4d.IDC_MY_VECTOR, c4d.DTYPE_VECTOR, 0))
# or short hand for that
descid_my_vector = c4d.DescID(c4d.IDC_MY_VECTOR)
# Build a descid for the x component of my_vector
descid_my_vector_x = c4d.DescID(
c4d.DescLevel(c4d.IDC_MY_VECTOR, c4d.DTYPE_VECTOR, 0),
c4d.DescLevel(c4d.VECTOR_X, c4d.DTYPE_REAL, 0))
# or short hand for that
descid_my_vector_x = c4d.DescID(c4d.IDC_MY_VECTOR, c4d.VECTOR_X)
For user data the first DescLevel of the DescID will always be c4d.ID_USERDATA which is necessary because the namespace here is not curated by Maxon or or the plugin author so they had to introduce a sub namespace to make the ID unambiguous (there might be a user data element with the ID 1000 but also a static description element with that same first DescLevel) So to just access a user data element with the ID 1 as a whole, you have have to do this:
descid_first_userdata = c4d.DescID(c4d.ID_USERDATA, 1)
# assuming this element is also a vector, the x component would be then
descid_first_userdata_x = c4d.DescID(c4d.ID_USERDATA, 1, c4d.VECTOR_X)
