Hi there, mailtophoo

And heres a tilable texture to us on the roofs so they appear thatched. To make the effect better you could use it as a bump map too.

Theres a ton of great stuff here on ShareCG that would make really good props in your scene. Have a hunt around I'm sure I missed a bunch of stuff. Just remember, as a courtesy, to credit the artist/model maker(s) and maybe give some feedback on their model page.

I'm looking forward to seeing the diorama you create with all this so keep us all posted and we hope to see something awesome soon.

Thanks, 

Maf.
