Hi,


Anyone had any experience with converting LIDAR to DEM or other formats that can be used in Terragen?

No but I imagine you could probably convert your Lidar to a VDISP map, similar to this thread:

Thanks 😊

I'll look into that.

I've found a good source for pulling point cloud from my home country which has lots of awesome mountains. I wanna import them to Terragen, but need to figure out how.

If anyone can find a good solution to this, I would be very happy  ;D

Ok. I've tried and failed so many times now. I know it's possible, but right now I just want Matt to implement and option to read these files and convert it to terrains  ;D
Just look at all the data that is there in the attached image. And the lovely landscape of course.

This one seems specific to LAZ files to OBJ: https://wiki.beamng.com/Using_LIDAR_to_generate_terrain

Does seem like a lot of these are on other paid for suites.

I'll try this one as well. Thanks  :)

You could look into using MeshLab which is free.  Looks like from searching it may be possible:

MeshLab Import LIDAR

You might need this to convert your .las file to something else:  https://www.danielgm.net/cc/
