Haven't posted anything for a while... Now I tested these pads (1981 for now), really great looking meshes. Some thoughts
1) Are pad perimeter "pedestal" meshes necessary? I mean "ground" underneath the whole LP territory. Because ground resolution is now almost sufficient AND also (deflected) smoke during liftoff in current Orbiter version is not rendered below the ground anymore. Earlier this was a solution, because mesh prevented smoke rendering below the ground (if you looked at launch from within pad perimeter).
Bad thing is also the fact that d3d9 client does not apply distance fog on vessels, so these "pad territory" meshes are clearly visible from afar. Launch structures themselves would not be so visible.
But it is just observation. I am not sure it is something wrong... maybe it is the right way.
2) There is some deflection smoke coming after countdown ends. But I understand that it is hardcoded (by thornton?). Earlier it was nice effect, but now with a multistage2015, when "my" shuttles are capable for creating launch deflection smokes themselves, seems obsolete.
Oops, I figured out TIMER values (most of them)...
