In particular, the Impostor changes will increase the memory requirements and may have some graphics-card specific behaviour I'm not aware of.
One way to address this might be to default the /sim/rendering/clouds3d-use-impostors to false, which will default to the previous behaviour (e.g. LoD nodes rather than Impostors), while retaining the geometry changes that are less controversial. > Does it interfere with other systems?

There's a stability risk from the Impostors, as these are new OSG constructs we've not used before, and which AFAICT aren't commonly used elsewhere. > Does it have the potential to endanger the release schedule? No. The changes are self-contained and could be easily backed out at any point. > What do you think? I suggest we default the impostors to be switched off by default. That's a trivial change to line 72 of cloudfield.cxx. I don't know if that impacts the perf improvements that Matthias is seeing. I'm also happy to have this left until after the 2.6.0 release. -Stuart ------------------------------------------------------------------------------ Learn Windows Azure Live!
