You can use more than 32 resources, at least in later patches of the game (I'm unsure about the earliest vanilla versions).So which is correct. You can only use 32 resources, or unlimited only limited by the programs speed and also the size of the shadows.pcx.
Hm, are you modding vanilla civ3? If you're modding a scenario in PTW or C3C the game will use the default shadows if you don't supply any, but I'm unsure what'd happen if there are no resources_shadows.pcx at all, I think this should crash the game.Also if I understand the above correctly you can go without a shadows.pcx and the program will run OK just no shadows will be visible for the resources, correct?
Your problems seems strange, so which patch are you using? This is important information. If you're using vanilla you should patch to 1.29, which is the last patch.
Are you sure that all pcx:s are in 256 colours? I think a terrain pcx in RGB could crash the game.
