Technically there is no direct "export" path to get textures out of Terragen 0.9x. The best way to get a texture of the terrain is to render an orthographic view of the scene (set in Camera Settings). You would want to set atmosphere down to 0 and the lighting to something reasonably neutral (near 90 degrees vertical), then render a square image at the size you want your texture. For example it could correspond to the size of a terrain - 2049x2049, etc. Keep in mind however that to get decent resolution from a ground-level view will require an extremely high resolution render. Many people do have good luck creating textures with TG2, but it is not designed for this purpose and requires a bit of manual work to get it to produce results.
