I have separtate saves of a landscape that use nodes, texture paint, or material (plane) lighting. The Dark Engine Exporter extension gives an error message from each save stating an error occurred while saving the .bin file. In the target folder, an .e file and an e_org file are created instead of the .bin. I use another program called 3ds2bin which gave a message saying that the file originally had RBG, cannot be converted to .bin with UV mapping, and must be reverted to RGB in order to be saved as a .bin. I either applied textures or painted them, but have not used material RGB to color the surface. I have even rescaled the landscape to a very small size, and I get the same messages.

Talking this exporter?
Also, are you using Cycles node materials? You need to use baked texture files assigned to the faces likely instead of simple diffuse material.
