So if your world has blacks from mods, will they show as unknown or will the map even load at all?
No idea.. I don't use mods.
Thanks, I had the auto detect turned off but the directory was to the terraria directory... Silly me, thanks.Try this:
Go to Help->Settings, uncheck AutoDetect Texture Folder, and browse to Terraria\Content\Images.
I had to do this, but I kind of assumed it was only because I'm playing the GOG version. Still, if you're having the same problem, I expect this will help.
I remember downloading this a while ago and it had lighting support (I could be wrong, though, it's been a long time). I very commonly build with tEdit, since launching the game and loading the world takes a long time. Having a nice mapviewer where I could enable lighting would speed up my work a lot.
