World partition with RVT assets

so…when i was looking for landscape blending assets i found out about RVT. but this tech means i have to create texture from above to use it as reference for asset. but this texture cant be infinite large in terms of optimization. and i’ve created a lot landscape parts with world partition, but when i started to use my grass with rvt it became obvious that on the edge of two landscapes grass loosing rvt color, cause next landscape dont have rvt actor, but even if it have rvt actor - grass have same material with link on previous rvt, so it will not work correctly, so solution is to create a lot of materials for each landscape part? what if i will use large asset like rock on the edge of landscape and try to blend it with landscape, half of rock will use rvt and half will not? how to fix that issue? is there any way to use rvt with world partition? cause now i can use it only for little assets inside of 1 landscape, not on the edge and not on all landscapes on the same time, so it is not effective.

You ever figure this out? I am having similar issues. RVT is really good but seems like it does not work at all with world partition and larger landscapes.
