Just downloaded the 111105 P2 beta. Placed it onto the vanilla 100830 P1 as it directed.
Using the stock TransX that comes with P1 with P2 upgrade, when changing stages, example you stage from moon to eject to earth, and do the eject burn then warp ahead, after it changes stages and you are Earth centered, the graphics of the Earth at center with large blue moon orbit and green ship orbit, both disappear.
Trying a different version of TransX, the latest, from
http://orbiterfixes.googlecode.com/f...raphicsfix.zip which works fine on the P1 version, it also has the loss of graphics following a stage change.
Getting the graphics to return: If there are still additional stages (stage 2 or more) after the stage change, then you can bring the graphics back by advancing forward into stage 2 then back to stage 1. Also if you exit the sim and restart current state, the graphics return.
Always a chance that I have simply made errors in the installation. Or that the bug is old news. If so, with either event, apologies.
