I having idea but I don’t have any idea how to make it coming true.
The idea is that let us say that I have a table (3d model) that I would like to drag into scene. But while adding it into the scene the table will get randomized objects on it.
Lets say I have made these 3D Models as shown on the image (https://imgur.com/sVfcEXp), Table, 2x Screens, 2x Keyboards and 2x Flowers.
Every time I drag the table (prefab?) into the scene then i would like to that the Screen, keyboard and flower randomizes on the table so it looks different each time and saves the object on scene as it becomes. I think it would be better to do that way with different separated objects than creating all the variation objects.
