Do you provide the loader code for TV ?
The software exports all the data to either ASCII or XML, your choice. Both are very easy to understand and read. I will be providing a loader to load the data from the ASCII format, which can then be used in any engine.
I will probably also provide tutorials on the website for how to use the loader with Irrlicht, Ogre3D and Truvision, since each of these are my favorite engines.
As for loading the actual data, you could simply export the terrain to a heightmap format that Truevision supports, the same for the terrain textures.
Then all the information about meshes is contained in the ASCII file, which includes a matrix for the meshe's orientation, or a quaternion of you wish........which can be easily intergrated into Truevision.
