Title: "Elevation_over_terrain_failed"
Post by: KW71 on November 03, 2014, 11:01:53 pm
Hi!!!
I was enjoying a low level flight trough a canyon:

pos_x = -337730.34,
pos_y = -6090611.4,
pos_z = 1863811.86,
rot_x = .859527,
rot_y = .02126,
rot_z = .474088,
rot_w = .189745

Suddenly I crash with nothing!

Next attempt, near the same point, same thing happens and got this message:


Elevation_over_terrain_faied

Elevation_over_terrain Invalid param (NaN)

To replicate, head into the canyon entrance at low altitud... Few seconds ahead... crash!!! (some times).

And here:

pos_x = -1391094.7,
pos_y = -4939183.2,
pos_z = 3791543.77,
rot_x = .855256,
rot_y = -.265899,
rot_z = -.404262,
rot_w = .185494


a big crack in the mesh.

What you were flying with?

In the first two attempts I was on the  AH-64.


1.- It was like hitting where there is nothing (AH-64).

2.- Same like one, but I got the message. (AH-64)

3.- After it I tried the combat jet; I received no message, but it was like hitting where there is nothing, and I got a strong impulse in the upper direction. I mean really strong, like being 50 ft over the ground, and a split second after, being 500 ft above.


I swear it was just one beer, officer.  :)


NOTE:   The second post is just about the mesh crack. No flying issues.

Any idea on this?

This occurs frequently in some locations (in this case Colorado Canyon). When I'm flying at low level, a receive a vertical impulse, which varies in intensity. When flying a plane, can push up me several tens  meters (even hundreds).

For this video (free camera) a have record three small chunks, until it happened (watch for a sudden small jump in the middle of the video):

I fixed a possibly related bug a few days ago, basically queries to elevation data could sometimes execute earlier than the elevation data are valid. I suspect there may be more erroneous cases in there.
