don't know if it would work as i imagine, but having the tile locations match across tilesets would mean you would have less custom raw files for the graphics packs wouldn't it?
Moving the tiles themselves, instead of the tilenumbers... I can have a look at how feasable that is.
It would help if the GUI would make a distinction between tilesets (the .png) and the raws behind them. For example CLA, Taffer, Ascii, Vherid, Matrix and Jolly use the Ascii Raws. The 3 masterwork versions, with the 3 different wall tiles, also use the same raw set.
If the GUI would identify CLA-tileset with CLA-picture and Ascii-Raws, it would already help a lot. There are only 5 different sets of raws. MDF/Obsidian/Phoebus/Ironhand/Ascii. But 15 sets of raws. That would eliminate 10. If I can move some tiles around, and get about.. half of the raw files to use the same numbers, it would mean even less problems. And less duplicate files.
The other way would be to make the GUI change the tileset numbers in the raws, instead of copying new sets over. BillyJack wanted to make some kind of script. Actually... I will try this first. I will let you know in a few hours if I can come up with something, IF you can alter the GUI to fit the needs. That was always my problem, I suck at coding. You dont.
