Started giving meshfusion a shot with the main door in the scene. Extremely powerful tool though it seems like it has its limitations still. Produces some inferior geometry and issues here and there, but as a whole it gives pretty great results fast. Can squeeze out shapes like these in matter of minutes, which is nice. Doesnt play well with some of the scripts I use and so on, but I will have to try to work around that :) Good stuff to say the least! Should speed up the process of creating this kind of asset quite a bit :)
Still extremely WIP and a long way to go, but now I think I have the tool figured out atleast.
