Oh you were totally right. I was indeed able to re-import some .23d files but then i don't remember how i manage to create them in the fist place. I just did it randomly.
I know it sounds like a stupid question, but could you please tell me how to save those files in the first place? So I will know for sure how i save them from now on?
I also noticed that different files are saved in different folders with their "exports" too, which is awesome.
Also could we get a "warning" for the "build" command? when i come back from "camera" and i hit the build bouton, it simply "close" my current work, allowing me to only either create a new object or select one of the previously saved ones. It would be cool if it does gives us a warning.
About the behavior you talked about, can it not only detect but if tiles will be overwritten and let us know but also give us the option to save with a different name (like when you want to save a file with idm and it suggest if you should add a number to the new files and keep both files)?
