I'm regulary using TrainzDEM for my routes without a problem in TRS22. I don't know how it will be with the new HD terrain
As Transdem can handle Lidar and the only issue is the height map getting demoted to the 5 or 10m grid in Trainz, I'm hoping it might just work with the HD ground.I don't think there will be any issues. The terrain is part of an imported TANE route. This route is really no different than anything else we've created manually except that the underlying height map used to create the landscape is imported from a DEM and applied in a 3rd-party program.
In the end, we'll have to try it and see which is one of the first things I want to try if I'm selected to do the testing in the Alpha release.
Clam,
Is there a way to load the Lidar data directly into transdem? I've used 1 meter resolution dem data, but not raw lidar data, and am curious if this is what you mean?
There doesn't seem to be a lot of support (or demand) for DEM support in the Trainz community, at least it appears that way to me. We need to be shouting about it from the roof tops other wise it will be another one of those things that gets pushed to the back of the list and never gets done. How long has Trainz been out now? Hmm.

That's probably because most of us use Transdem or the much older method of Microdem / Hog and some even height maps I believe?
Granted as the opposition has been able to import Dems for some time I am wondering if there is any intention to include this in Trainz at some point?
I purchased Transdem and it works. The author of the software (geophil) apparently saw some demand among Trainz users for this, so he programmed Transdem. Why would N3V feel the need to program something that has already been done by geophil? I would rather have N3V do other things that need doing.
As far as Transdem not dealing with HD terrain - why would it? In my opinion, HD terrain capabilities, when available, are for final tweaking of a route in Surveyor - not route creation from scratch using Transdem.
There is DEM support needed somehow. You want the high resolution of dems to go directly to the high resolution HD Terrain, otherwise you are missing data that is then made up by the program. Essentially you end up faking some of the data, instead of using 100% real dem data.
Of course, in the best of all possible worlds, you are correct. The question then is whether you will need a super-computer to create such a route, since it will be HD terrain everywhere instead of only a few places, which is how I envisioned this would work.
It will be interesting to see how N3V proceeds with HD terrain capabilities and how Trainz users respond.
TransDEM already deals with high resolution DEM files very fast. TransDEM already varies the grid with higher resolution near the view point of the tracks and lower resolution grid away from the tracks. I imagine that can continue with the new HD terrain.
