Bigger textures than 1024x1024?

[Ginev]

Can Battlefront 2 use bigger textures than 1024x1024?Cuz im making rocky models in zbrush and then texturing them into blender (its more easy for me).However when i make a 1024x1024 size texture it look very low quality.When i try 2048x2048 it look the way i like however battlefront can't use more than 1024 cuz for me the 2048 look totally black into game.Some solution?

I know this topic is little old but i have to mention it:If you guys making your own custom textures and want to have a little more detail on them you can use 2048 on 1024.I tested it and its working.
