Hi Jason, osgParticle::PrecipitationEffect is design to be effectively infinite, no matter how far you move it should repeat endlessly. I've done lots of testing on town sized models and it certainly works in this context fine.
My guess is that your scaling of the scene has introduced issues that the shader isn't able to cope with for some reason. Try loaded a model that is of a 1:1 scale to see if it works fine. Robert.
