I have found and created some .dds images which I'd like to incorporate into my track as ground textures. If I was to build an xpack for these how are they to be defined in the xpack in order to be visible in the terrain section once the xpack is moved into the projects folder? For example I've made a number of xpacks with images for walls to be used as billboards or as the replacement texture for a SO wall. I now want to make a xpack for ground textures. How do I define that in an xpack so that it can replace grass or cement in the terrain section? Sorry for the basic question- could not find anything here on this after searching the forums. Trust it is a simple thing to do.... Thanks!
