I would like to create sprite that have random opacity , lifespan , scale and twist when created
So , I added this into creation expression :
particleShape1.opacityPP = rand(0.1,1);
particleShape1.lifespanPP = rand (1,5);
particleShape1.spriteTwistPP = rand (-90,90);
particleShape1.spriteScaleYPP = rand (0.2 , 1.2);
particleShape1.spriteScaleXPP = rand (0.2 , 1.2);
However , when I rendered it with hardware render , the result was no as desired !
It was as if the particle have random opacity , lifespan and sprite , twist in every frame !
Yet , what I saw in maya working space(real-time display) was absolutely correct !
How come it could happened ?
