No Steve, I have just checked and it’s the same when I change the emitter to Point. I have changed various parameters and the problem persists; shading – (on and off, and Light Falloff), transfer mode, orient to motion and custom particle type – (sphere, sprite, textured polygon etc.)
UPDATE: I think I’ve found the culprit, but I can’t reproduce it. It seems it was caused by having a very particular shape in the ‘opacity over life’ box. The shape I had was solid until about three quarters through the life of the particle, then a tiny vertical drop (about 10% of the height of the box) and then a downward slope through to the end.
I have been trying to draw that shape again to reproduce the effect, but I can’t. I guess I’ll just have to try and remember this if I ever see that problem again.
