Hello everyone, I live in France and in the last summer the government started releasing very detailed LiDAR captures of France, and I'm trying to use this data to make a map in BeamNG. I first tried a lot of stuff when it got released, but didnt manage to go further than importing my collada map in BeamNG (after removing all trees and buildings from the original dataset). If I remember well I was stuck in a place where my game would crash everytime I would load my map. So now I'm trying again and I'm stuck at the basic level creation in BeamNG. I feel like we don't have any up to date documentation or tutorial on how to create a map from this type of data. Of course there is the tutorial from Ewanc, but its getting really old and he is using US LiDAR that is already classified which helps remove the trees a lot faster. For me the main challenge is getting a nice and detailed terrain without keeping 20M faces, which I struggle a lot in the forests my village has. You can see all the dark stuff is thousands and thousands of faces making very small surfaces which are the tree bases. All this stuff is really annoying to remove, as the only way I think I have is to cut all the forests, lower the point density as much as I can, and mesh these seperately from the roads and plane stuff. For reference here is the base forest with the road going through it. There is also B25Mitch Map in a Month tutorial, but all the trees also already got classified so the terrain is already nice and clean. I know this message looks more like a "help me please I'm about to give up on this project I already spent so much time trying to make", but in the end I'm only asking for a real up to date tutorial on how to make a map from LiDAR. I don't care for the moment on how to add buildings, forests and all that stuff. For now I only want roads, terrain relief, and thats it. Thanks a lot Etyop
I found a heightmap I did back in august 2022 when the LiDAR got released and that I couldn't manage to loadfinto BeamNG without crashing the game. It seems like it is now resolved and I can place finally start working on my map! It looks really good, i'm so happy guys hopefully I'll be able to share progress soon!
