lost terrain resolution

I had a 4096 x 4096 splat map applied to my terrain (seemed to display at 2048 x 2048, but that’s acceptable) I made a few tweaks to the splat map in pshop saved it as a new file, then applied that to my terrain now the resolution of the bitmap’s dropped to 1024. I can’t get the resolution upped again. Tried going under Terrain/Set Resolution. It says my base texture resolution is still set to 2048, so I don’t know what else to do to get my resolution back. Any suggestions?

Have you checked the import settings of the texture?

I forgot about all the settings that open up when you double click the splat map. Thanks
