This is the situtation: I have created 4 FBX models in 4 colors, so 16 variations. I imported one into my sandbox server and added some other entities and exported them as a one JSON. I was hoping I could copy the JSON and change the URL to the FBX for the 15 others. Didn’t work. I suspect it has something to do with the seemingly random serialized EntityIDs?
So, in this context, I want to understand the EntityID; how is it generated? Is it random or does it contain other information? Can I make/write my own EntityIDs? Or is there another reason my copied JSONs will rezz all the entities except the other 15 FBX models?
