Well it only took me 2 weeks to get from this:

To this:

Which is pretty good going! I now have a basic blockout of all five floors of the manor house, and I've spent the last few days fiddling with the navmesh and my Monica can walk up and down stairs and into every room on every floor.

I have also spaced out the NPC characters (the yellow capsules in the second image) into the rooms the player will find them in. Next task is to take some time walking around, working out travel times, and adjusting the player walk speed and turn speed if need be.

Now I'm planning what other tasks I need to do in the next couple of weeks, and I'm thinking maybe a front end menu (which will just be a special page of the journal), adding spawn points so that the player can 'fast travel' between rooms if they need to (but I need to make the map for that first), but I also need to do more work on the blockout in terms of hiding walls blocking the view of Monica, which is a huge task on its' own.

But otherwise, happy with how it's going so far :)

Tony.
