Hi Nick, I've just tried your test model and see the problem but as yet don't know the cause. I experimented with changing various parameters and consistently it looked like the textures flipped halfway through their lifetime. I have had a bash at looking at the revision logs for Particle.cpp and ParticleSystem.cpp to see if there is any change that looks like it might be repossible but the old server isn't responding right now so can't check.
