Sadly No they are market assets. But most of them are very simple for the most part. For example I place a wall from the abandoned places asset. It doesn’t have any materials on it. Then I place a material and it takes forever. This happens with any material asset I just import. If the FBX file has a asset on it it takes double the time. Once I have loaded it the first time it is fine. But here is the rub. Lets say I want to delete a overview map. I right click on it or just click on it and I am waiting 5 minutes for everything to load before I can delete it. It is lame… I want to turn that off…
