I was just wondering if it would be possible to create a way to assign a terrain texture to a model surface that we add to the game world? In that way we could add grass, trees, etc, and that the shader model for the terrain would also work for the model. The reason I as is that I recently created a map in which I created a tunnel and I was trying to make the texture match the terrain. I was able to fudge my way around to get it looking somewhat decent, but you can still tell it doesn't match during certain lighting conditions. Either that or a way to create a hole in the terrain which I know from reading the Torque forms that that's a long standing bug-a-boo with the community ( yes, bug-a-boo is a real word ).
interesting question, qould like to know that too. did you try to rename the texture used by the mesh into one of the official layer names? like "Grass", "Rock", "Concrete"? no idea if that would work, but the terrain materials physical behaviours are given by name references in a global file as i know.
I've given my surface material a couple of different names like "terrain" for one, I forget what other names I've tried because I had the same thought. Nothing I did worked. I was able to modify one of the rock textures from within the game and apply it to my model; it looks passable ( Stockcar Madness map ) but the way normals maps, lighting and shadows work on the surface you can tell something isn't right.
