This is really sad, pflow without data operators is almost useless to me :(
You can still use pFlow with data operators, it will just mean particles will be unique geometry, not instances, so it will work exactly like it always did with all other renderers. V-Ray has VrayInstancer, which is kind of instance scattering tool, that can use pFlow particles to distribute instances, but you would not be able to use pFlow to affect mapping on those instances either. So in a nutshell, Corona is limited in this regard, but no other renderer does it any better. Ultimately, it's a limitation of old and obsolete Max/pFlow architecture.
