I noticed that this program, AutoTileGen (http://www.autotilegen.com) just got Greenlit on Steam: http://steamcommunity.com/sharedfiles/f ... =239448597
It looks like any easy to use tileset creator with tools that blends images together and rounds the corners and such. There's also another map editor tool included called AutoTileSet that just got ported to Construct 2. Seems like a promising tool. Has anyone used this? Or by looking at it, does anyone have an opinion on how useful a tool it would be? There's a free version of it available.
Also, it looks like there's an indiegogo campaign that's made its goal, but has a few days to go (link is on the Steam Greenlight page). Getting it through there looks like it gives a Steam key as well a regular version. I'm not sure if there are any other stretch goals to unlock there or any exclusive content, but it looks like you also get some Unity tools if you get it there, which might be attractive to some people.
