GPU Sprites and Initial Size

Is it a bug that GPU Sprites cannot have a distribution range for Initial Size? Only the min value seems to have an affect, making them all the same size and my fx look less interesting. I’m using 4.4 and not tried in 4.5 yet, is it the same?

The docs say “•Initial size is determined at spawn time and may vary per-particle.”

but that doesn’t work and neither does Size Scale with a distribution.

Also FYI:

The docs list under “Supported Attributes”
SubImageIndex
•The sub-image index varies over the life of a particle as defined by a curve.
•The curve is shared among all particles.

I thought subUVs were not allowed on GPU Particles.
