In general when dealing with particles is it true that the linstep function can achieve the same results as a B/W ramp?
For example the following I put together...
float $normAge = age/lifespanPP;
opacityPP = 1-(linstep ( 0,0.5,$normAge )) ;
has the same effect as throwing a ramp based on lifespanPP in the opacityPP attribute. I was just wondering if this is quite a common practice to use one or the other.
