Tear in ground mesh... fixable?

[d1dnmdv]

Hi, Anyone know if a tear in the mesh/ground can cause problems or if there is a way to fix it? I was texturing my route when I noticed a hole in the mesh/ground. I was able to make it smaller and less noticeable but not remove it by elevating the ground and then extending my river bank so the tear is flat and not as large as when it was vertical on the side of the river bank. This is what I am asking about:

*Edit - I changed example to show the problem better (plus make it smaller image). All water has been removed and I stretched the mesh face more so you can see through better. I have circled the vertex that has become detached and outlined the mesh face in wire frame mode.

I will probably park or plant something on it so it is less disturbing if there is no danger or way to make it go away:hehe:

It could be the water mesh showing through there, it certainly looks that way, rather odd to be honest, but if the ground is like that (slightly lower than the water) the water WILL show through (unrealistic, but hey, what can we do) - try adjusting the water 'height' down a few feet, see if it helps.

Or you could gently raise the height of the piece of land in the Topology flyout just where that spike of water shows through so that the water level can remain the same, which could be important if you need to retain the same water level in other parts of the "lake".

This technique works best with Adjust height button selected and the radius and sensitivity dials set to minimum. You can then gently adjust the small piece of land until the offending piece of water disappears.

I have found these on my route. What I learned was that one of the baseboards had a 5m grid and the other had a 10m grid.
In this situation my guess is the closes baseboard is 5 and the one behind it (the one we are looking "under") is 10m. If you update that 2nd board to 5m you can close the gap and new gaps wont show up when adjusting the terain.

Hi, Thank you Sure enough - the water grid was 10 and the land was 5 meters. It did not kill it but I can barely see it now after massaging the spot

You guess hit the nail on the head hear. I've run into the same problem as well before.

I would like to add though. If you've already textured a baseboard at 10m, don't change the grid to 5m! The textures turn blocky and never seem to blend correctly after that. I ended up deleting baseboards and redoing them because of that issue, although in a couple of areas I said screw it and put lots of extra trees around to hid the squares because there was too much work done in that section already.

Hi, I thought about just starting over since it is a TranzDEM based .gnd file for the Port of Providence, RI but I had already placed, adjusted & textured too many things to want to re-do

It appears that Trainz uses 'vertex based painting' on the ground (aka ground mesh). Specifically the textures seem to be mapped by Trainz to corners of the grid (aka vertices) and that may account for the chunky look up close between the 2 sizes of grid as you have half the vertices to attach ground textures to...
