Firstly thanks Jean, >>You mention OpenFlight format, is this because you have Creator or some other modeling tool that reads OpenFlight? No, not exactly. When I create terrain I have to support to different model textures. One of show day and the other show night of textures. So we choose flt format on terrain database.
Your advices awesome. I know VPB is a useful tool on terrain creation but I only need to GUI support as in your advice BLENDER. I will try VPB on PagedLOD and converstion to OpenFlight. If OF support PagedLOD it will be good start I think :) Thanks again Jean. If at this point anyone have any idea about terrain creation, I appreciate all of them. Best Regards.
