About the Wire Frame Grid
by Jim Steven, MCSE,

My wire frame grid has different density when in 'F9'.

I'm viewing the wire frame (hitting 'w') in 'F2' mode. Then when I change to 'F9' mode I see more points in the wire frame. This makes the landscape look different when shaping it and when running a train on it and is a big problem for me. As I'm doing a mountain line I'd like to have those extra grid points in the wire frame all the time to model the landscape with more detail. Is it something I do in the geometry extractor or in the route editor? Do I have to decide at the begining of a new route or can I change the level of terrain detail as I go along?


I think what's happening is this; When pressing just the 'W', it just shows the standard grid, and 'F9' is the key for altering terrain.  I do believe that pressing 'F9' activates the detail level that was entered when you first extracted the new route. And I do believe that this can be changed. Open the Route Geometry Extractor, and load your route, including the Quad Tree. Select edit, and then select Route Values. There will be a setting called 'Terrain detail scaling factor', and that is what I think that you are looking for. I have mine set at 0.20, and so far I'm pretty satisfied with the way the terrain is looking.

{Comment by Jim Ward} That seems correct. I noticed it while I was creating screen shots of the Wire Frame to demonstrate the "Press V to cut out a triangle" process we use to create tunnels. I was trying to explain how setting the tile Error Bias to "0" and setting the terrain detail scaling to a small value would make it easier to cut out smaller terrain patches and saw the differences in the Wire Frame images.

{Comment by Okrasa Ghia} When in texturing mode (F7) select a terrain patch and right click to bring up the menu. Select 'Error Bias...' and set the value to 0, now all wire mesh grid points are used all the time. I do this now on every terrain patch where I lay track and leave the others at the default value (1).
