Is this possible at all ??, Ive made a few buildings and landscape features that i would like to impliment into FSX, mainly for personal use but if i can improve on them i might take the plunge and share them, ive imported the objects into game but im struggling at matching them up, like a waterfall and dam feature thats stood too far off the DEM at the bottom and at slightly the wrong angle, going back and remodeling is a tedious job and takes the best part of a 5 hours, and all that to go in and find out its too much or not enough is a bit demoralising, so, my plan is to navigate to my desired location, somehow make a 3D copy of the area, which is only about a thousand meters squared in total, and import this into a 3D program (3D studio max 9) so i can create the model perfectly the first time and then just delete the terrain leaving me with my model for importing, im not an expert when it comes to these things, and i could be well of the mark with this one, but it would make my hobby so much easyer lol, so please, if anyone knows of a way to do this, or knows if its impossible could they let me know, that way i can stop worrying about it lol Many many thanks for taking the time to read this guys and many thanks in advance for any info Srimera
