Now the release branch has been created, I've committed these changes to simgear/next, flightgear/next and fgdata/master. The Impostors are switched off by default. Unfortunately, one of the side-effects of switching them on is that some clouds will "jump" into existence, caused by an impostor being generated while the cloud is out of range, and not being re-generated (or switched off) until the cloud is well within range. If you want to use them,you will need to set /sim/rendering/clouds3d-use-impostors=true _before_ generating any clouds (e.g. from the command-line). There are also a number of properties under /sim/rendering/ to set the LoD and impostor ranges. I've set them such that a typical scatter layer of cumulus under Global weather will generate ~20 Impostors, and ~200 lower level LoD nodes for some 3000 clouds. Feedback welcome as always. -Stuart ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
