Bug – Material Textures layers importing for world composition landscape

Hi guys,

I have issues with importing Material texture layers in UE4 world composition.
I created a tiled world in World Machine made with more than 240 tiles, then I export 3 tiles 2017x2017 to UE4 to test my map

When exporting the Tiles UE4 see them as 2017x2017 and everything till now is fine.

The problem starts when I create a material and try to import texture layers

1st I get an error that the imported layer have low resolution than the landscape even if my landscape was imported as 2017 tiles

And this will result on a stretched layer from the top side and not in the right place as you can see here

When I check the landscape resolution I find that UE4 changed it to 4033 even if I imported it as 2017

I tried to change my layer texture size from 2017 to 4033 in photoshop hoping this will fix the issue, I don’t receive any error anymore about unmatched resolution but after I apply it I can see its clearly bigger than my tile and don’t apply correctly.

So I’m stuck in this loop and I don’t want to import my tiles as 4033 since I believe it’s a very high resolution and with over 200 tiles this may cause big performance issues.
Anyone experienced this problem and can advise? Thanks.
Here is a link to the tiles and layers I used if someone want to test it.

PS: when tiles are imported they will be in the right side of the world composition window

u have to unload every level beside the one you want to apply your weightmaps. with your amount of tiles good luck:)
personally i suffer from crashes if i add more then 2 weightmaps with 4.16.2 for a 8x8 1009 tileset

Yes I already fixed the issue by just loading the one tile and applying the texture layer.
I don’t have any performance issue, I can load 20 tiles 2k resolution each without a drop in performance FPS at 150, maybe when the tile is fully meshed then can just load 4-6 tiles.
My setting are: Titan X pascal, 32 Ram, i7 8 cores 6800 at 4k gihz
