creating a harge pool of individual customized presets is amazing and awesome because it allows us to have even more freedom and creativity when placing more diverse pairing animations into sandbox maps.
However, when the preset folders are extremely full,
the game freezes and sometimes crashes when selecting, summoning and\or loading every new character into the scenario or includig new scenes,
(even if you have powerfull pc spec and processor to do so)
it is nice and highly recommended, [and almost mandatory] to backup collections, game assets, plus all custom files , old and new, regularly, specially if you are messing around and testing too many showroom maps, making new buildings and\or creating new presets every day. Too many cubes, objects and components in one single map, crashes fps very often. Sadly, it prevents us from creating an open world. But again, as the tool itself says, it is just a small 'showroom' preview. It is not design yet or ready and capable of allowing huge amount of several maps put together by importing all clusters and pieces of even larger maps.
Assimilating an optimized U5 Engine gamecore upgrade will be the holy graal for better performance.
And if by any chace , adding custom sex animation tools in future game updates, the sky will be the limit for sandbox adult playground.
