Is there a way to control the orientation of sprite particles so that they are not just camera-facing?
Idealy, I'd like to be able to orient them to an axis.
Many thanks in advance.

Try something like this.
Creation expressions:
particleShape1.spriteScaleXPP = rand(-1,1);
particleShape1.spriteScaleYPP = rand(-1,1);
particleShape1.spriteTwistPP = rand(-180,180);
Runtime expressions:
if (particleShape1.spriteScaleXPP > 1)
{
particleShape1.spriteScaleXPP = -1;
}
if (particleShape1.spriteTwistPP > 180)
{
particleShape1.spriteTwistPP = -180;
}
particleShape1.spriteScaleXPP += 0.01;
particleShape1.spriteTwistPP += 2;
Attached is a sample file to see what I mean.
I'm very excited to help Mike after all the times he's helped me. I hope it works.
