I haven't made any massive builds yet. I'm still really learning the system, but it's very, very robust. I wanted to just post a few images. I know the game is a work in progress, and I'm definitely hoping for a lot more elements (particularly in furniture), but still... I hope you will enjoy a few of the rooms I've made with it so far. I am not using any mods or anything, this is straight vanilla game (I am using posters and decals).
I am hoping at some point that we will be able to paint sides of blocks, instead of only able to paint the ENTIRE block? It would make some of this far, far easier, due in particular to problems with arches. But also, I have to put sheets on every wall and then do weird machinations to paint around my arched windows without making the outside weird.
