PnP TerrainCreator - Forum

Hi everyone, i m using pnp terrain creator for terrain creation but i faced too many problem while exporting Heightmaps and Terraintextures map, i cant find the option how i export my material files used in the terrain??
I have the 1.2.2 Pnp community edition (unregistered) is this the problem or something else? and secondly while exporting the mesh Heightmap to 3ds exporters it gives me error: "The Texture map and the light map have different dimensions", how can i set the both dimensions same as i have no light map.
