Hi lovely community, i'm still an absolute beginner when it comes to asset creation. What do I have to pay attention to if I want to create a mansion that has three floors for example, but the entrance is on the middle floor as shown in this example? https://earth.google.com/web/search/9410+Sierra+Mar+Pl./@34.09642236,-118.39471231,247.54742635a,142.22622108d,35y,-81.17177441h,50.25349286t,0r/data=CigiJgokCSwelnNZC0FAEQWRFtVkCkFAGeGYA9aJml3AIQhyPJvtml3A Does the bottom floor then have to be in the negative area in Blender in relation to the z-axis? I've already seen some such assets in the workshop, but I'm just wondering what exactly I have to pay attention to. https://steamcommunity.com/sharedfiles/filedetails/?id=1791879291&searchtext=SoCal+ I look forward to your answers and am glad to have joined this community ♥ Kind regards, JJ
