GLS: Your presence is requested in the official terrain bug ticket: https://www.orbiter-forum.com/project.php?issueid=1408 as you were the one who did the terrain modifications as the tileedit tool refused to work for me.

Sorry I missed the party, but I was sleeping.

On the hidden triangles in SLC-6: the TSM umbilicals and piping cost almost 100k triangles! Which IMO is a bit too much, especially when most of it is hidden inside the TSMs. Just deleting the hidden triangles cuts about 10% of the original size (at no loss for detail), but we could delete the sections of pipes that run after the "back support" (a bend and vertical section), and much more could be gained. This could be done in time for the release. In the future, the pipes could probably be simplified: a slight decrease in their curving (so less sections) and also decreasing their detail by using, e.g., 10 instead of 20 vertices around.

Again for the record, I'm not against detail. But this alone costs almost as much as the entire OV, and it's small and mostly hidden.

Also, some smaller details could be done as textures, since we really rarely get close enough to notice the difference.

Ok, after losing a good chunk of the changes, because half-way thru saving the mesh blender decided it would write gibberish, and moments later my pc when kaput, I got half of the work done on the SLC-6_STS_LaunchMount.msh file.
Results so far:
>> original
v 114920
t 142321

>> current WIP with all groups cleaned except LOX umbilical (which is on the LH2 side )
v 97747 (-14.94%)
t 125261 (-11.99%)

If 10-15% isn't impressive, then 20000 vertices and triangles is. And probably there is still another 20K inside the other TSM.

I've managed to reduce the LOX TSM umbilical triangle count by 84.8%. So down from 58,791 triangles to 8,947 triangles. The vertex count is down by 71.4% from 27,128 to 7,762. Note these numbers may not be correct once exported to the msh format.

I'm sure I could get the LH2 umbilicals down a similar amount.

If you are reducing in AC3D. When you export as .msh the vertices stay welded. When you import to AC3D is when the vertices get unwelded for some reason.

Good!
So there is no point in me continuing the work in the umbilicals at SLC-6, right?
I'll commit it anyway tonight, as there were changes in other groups, and then I'll move to the MST, as the grid structure there seems to have fat.

I think there are still some issues with the latest mesh.

1) There is an area located on the upper wing close to the leading edge where the texture looks wrong. This is difficult to detect when viewing Atlantis/Discovery or Endeavour but it is quite evident looking at Columbia and Challenger original since they have white tiles with lettering in that area.

2)There is also a problem where the black metal strip inside of the RCC merges with the wing white tiles.

3) Last is the old Side Hatch issue which was fixed time ago but now shows up again.

Needs some fine-tooth remapping.

In image 2, it's the gear wheel well poking out, and I noted that in the OV mesh issues ticket.

I don't think, that's what it is. It looks like distortion, where the RCC meets the black leading edge tiles.
