   Multitexturing combined with hard edge tiles.
  I'm not sure what the standard approach is to a strict tiling (no multitexturing) system really is. I assume its each tile is its own vertices not connected to the tile next to it. Then when you texture the tile it tiles with hard edges. You create as many as these as you need for your terrain. Now what I want to do is have the ability to multitexture as well as create hard tiles. What is the best way to do this? I have 2 ideas that may work but not sure if they are the best method.A) I could make this difficult and add vertices in the terrain to double up vertices where I want a hard tile to be. I could then just multitexture everything not doubled up and then the doubled up edges will be hard where ever they are.B) I could just stick with the basic tiling method I explained at the beginning and create a separate tile for each tile not connected to the one next to it and texture it. Then to do multitexturing I could apply multiple textures to it. I don't know if this will work because two tiles next to each other may not match up properly. In fact they most likely won't. I would have to make sure that the UV coords of the textures matched on the edges of the tiles. Not sure if this idea would work well or not.c) I could create a terrain for multitexturing and then add hard tiles on top of that where needed.d) I could finaly create the normal terrain and use a similar approach to (c) except I would also remove any vertices in the main terrain that arent needed or covered up by the tiling terrain.What is a good or the best approach to this?
