Hi Janis,

I verified both the template and the portable versions of the .blend and all the main collections are inside.

You have probably opened the light version 'Z-Anatomy-lite.blend', the last file of the folder, which is available to let the people with weaker devices select only the systems they want to see.

It can be used exactly as the regular file; clicking on the collections imports them separately.

To get the whole file and the configuration, you can double click the 'Z-Anatomy.exe' that is stored just before the 'light' version.

I tried to enable everything but still, all could see is not much? I definitely didn't do something but I definitely did everything from readme :)

Oh, allright, I got it.

This is the file of Biomechanics. It only contains the bones and insertions because the other structures haven't been parented to the rig yet; only the skeletal system moves for the moment.

The whole file of anatomy is at the top of the page 'Atlas'; the one you use is the one at the bottom of the same page; it is a starting point for the people willing to develop the study of biomechanics using the 3D files of BodyParts3D/Z-Anatomy.

These two files have been separated because the parenthood relationships that are needed to import and recover the organization in Unity (Anatomy) contradict the parenting needed to rig the structures (Biomechanics).
