Landscape weight maps

[TessyTe1 (TessyTe)]

Hello, please help with advise.

1. I have created height map and splat maps in Gaea, and for some reason it produced few sections with artifatcs instead, have tried to rebuild it and it have fixed previous sections, but created a broken new one
   
   
   
   
   

UPD. Figured out that there was a problem with the faloff splat map itself - when I turned it off I got rid of the artifacts, soI don’t need an answer for this anymore.

2. Also I was trying to utilize Epics Water System, but I found that the water never renders when I use splat maps. Can sombody give an advise what I should to read to determine what is the problem?

I have resolved it.

So the deal was with the mode of weight map import, it was set to “Loaded only”, and you need to set it to All to make water finally appear
