How does a complete project go from a zSpace300 all-in-one to an Inspire laptop
That depends on how your project is built. Rather than explain every possible scenario, please describe your project in as much detail as possible. Are you using Unity3D? If so, what version of ZCore are you using? Are you using URP? Any other details you can provide would be helpful.
The current zCore version is 6.1.2. Is there any place where I can view the version number of the script?
Knowing that you are using zCore 6.1.2 should be sufficient context.
We have some documentation at the following link explaining differences that will be encountered when running on the Inspire laptop.
If you do not find the answers you are looking for in that document, then feel free to explain any troubles you are having in as much detail as possible. If you can share example code or projects, that would be an ideal way to convey whatever issues you may be experiencing.
