This is a place for me to post tiles that I have made and hopefully receive feed back. This might be a good place for me to post tips and tricks on how I did certain things. I usually start with a rough sketch of the dungeon layout I have in mind on good old Graph paper.
Graphed out
I then take the idea and flesh it out on 8.5 x 11 paper that I grid out with one inch blocks. In my mind, one 1 inch square equals about five feet.
Sketched out
With the tile sketched out I usually then take the idea into photoshop. I use to scan in my sketches and then trace over them with the pen tool but I've gotten a bit lazy lately and decide to simply start fresh with a blank canvas, using my sketch as reference.
I'm trying to discover ways in photoshop to keep the tiles as real looking as possible which is not an easy task for me and I kind of "wing it as I go along."
In this example I am converting my prison block and needed stone flooring and walls but I didn't want plain one inch squares. So I made a one inch by one inch tile, made my design and saved it as a pattern, I could then copy and paste in the design in the places I needed.
Long story short and about eight hours later I have this:
