We are working on it.
What surface do you use for scatter. Is it heavy?
Try to uncheck Border Behaviour\Use Surface Border
Not to much. It’s a grass surface for a futuristic desert city 
. I will try with uncheck Border Behaviour\Use Surface Border. I will scatter about 3.000.000 proxy grass model. It’s ok, but the pre-scatter process it’s about 6-7 min.
We will think about it.
I know Vue spews out thousands of cache files for it’s ecosystems, so maybe something similar could be done - some kind of “Scatter Cache” which calculates and efficiently writes necessary information to a file, where you can tell it to load from that file rather than re-calculating every frame or whenever you render, when you’re not working on VRS settings.
That would be REALLY amazing…
