texture files not generated

I'm getting the following error when I run my app. I'm trying to make changes to the material and texture of the ground. This output seems to be looking for a file my_texture.1.1.png but, MapSplitter did not generate such a file. What must I do to enable generating of textures. I have the texture file in ImageFile of my *.cfg.


Texture: spot_shadow_fade.png: Loading 1 faces(PF_R8G8B8,128x128x1) with 5 generated mipmaps from Image. Internal format is PF_X8R8G8B8,128x128x1.
Error loading texture my_texture.1.1.png. Texture layer will be blank. Loading the texture failed with the following exception: OGRE EXCEPTION(6:FileNotFoundException): Cannot locate resource my_texture.1.1.png in resource group PLSM2 or any other group. in ResourceGroupManager::openResource at OgreResourceGroupManager.cpp (line 753)

Any help much appreciated.
