I think there does exist the concept of a vec1 value. It's a 1-dimensional vector. Something like just an X coordinate, for example. Their length is their value.
Yes this is something I would like to share like a sort of tool for doing assets presentations for example. But at this stage it's only for my own use.
Thanks for the info Twister. By the way, is it possible to set up the grid like a guide system? For example, I could have it in the background as well as on the floor?
