Well, I certainly will try that. I suppose my concern is that it seems like this feature in it's current state may only be useful for exactly that scenario. It seems like the developers have only planned for a workflow that requires most of the terrain creation and editing to be completed using the legacy grid system before upgrading the route to HD terrain to apply the final tweaks. I just find it really depressing to be honest. Do they actually try and do any kind of route creating in-house using their software? The very first five minutes I had it to play with show glaring issues.Try upgrading a route to HD terrain and having a play around once you have scenery placed around it, you may find you are pleasantly surprised. I certainly am and I do see it as a huge improvement over the 5m/10m grid, to the point where I don't see that I'll use anything other than HD in the future.
The 10m ones look just as good to me Phil. NiceHere are some comparison shots for b4 and after my 10m base boards route is run through HD conversion. No post capture processing has been applied. The differences are subtle. the most obvious is the rounding of the hard edges. In game the world feels a little more detailed, but I'm not sure this comes across in these screen shots.
Just for interest, a similar shot I recently posted captured in TRS2019 (resized and sharpened)
