Hi

I'm building a PCG pipeline for a open world game. I tried to seperate HDA output and manual data in different edit layers so that we can work simultaneously with landscape artists.
I managed to get it working with a single landscape. But things turned out to be unexpected after enabling world compositing and splitting landscape into mutltiple tiles.
The height data seems to be correct, the painter layer just went wrong.

This are the problems I encountered:
1, can't update one tile without affecting other tiles.
2, can't update HDA output layer without affecting manual layer.

Anyone has same issues? Please shed some insights.
Thanks
