karen - i dont totally understand what you are saying...
but the RR figures are offered primarily to animators, who want to reduce their rendertimes by replacing the massively bloated V3 mesh with a somewhat lighter one.

there should be a warning on the V3 RR page saying it will not work with V3 morphs. in its current form, it APPEARS to, which increases its appeal to buyers. then someone buys it, finds out my GND morph for example doesnt work with it, and emails ME with a flood of technical support questions.
its complete BS. in order to puff up the appeal of one of their products daz is dumping a load of tech support problems on us merchants.
