okay... um..
For one, the "unit" of messure for a TA map. 1x1 or 30x30, is that value times 512.
1x1 would be a 512x512 image. 32x32 maps are 16384x16384. The texture has to be divisable by 512 otherwise it won't even work in spring.
Also, the current MAX_SIZE setting in the GUI program is the same for the original converter. And that is 40x40.
I don't even have files to test anything over 58 because photoshop can't create/load images greater than 30K pixels
If anyone wants to zip one up (incl metal and height maps) so I can test, then I could work with it. Just make sure your images are 24bpp!!!
Also, it would be pointless to make maps of that size as Spring couldn't even load them. I'll have to check into the code for that.
