Hey everyone, I am encountering a bug (or what it seems to be a bug) with the painting feature of Unreal Engine 5 Landscape tool. Basically I have three materials set on the landscape. I am able to paint them all in the whole landscape EXCEPT in a specific portion of the landscape. When I cross this line (you can see it visually in the image) it won’t allow me to paint anything that isn’t the current material (the Rocky Moss).
I have set all three of them exactly in the same way so I am not sure why. I have tried restarting Unreal and reloading the level. I have also tried re creating the material but nothing. I really don’t want to have to recreate the whole landscape because it’s quite big and a lot of work went into it. Any idea what it might be? I am using Unreal 5.6.
P.S. I have also attached the material nodes in case I might have set something wrong. Thanks a lot guys and let me know if you need anymore details.
Hi @Thunderloud777 ,
I was researching the issue you’re experiencing, and it seems like it’s been happening since around 2015, as shown in this trend.
I went through several posts and one solution people found was: “Select all texture samples and set the ‘Sampler Source’ to ‘Shared:Wrap’. in your landscape material’.”
I’m also sharing a video that explains in detail how to paint landscapes using Megascans materials in Unreal Engine 5. It’s a bit old, but it might still be helpful:
How to Paint Landscape with Megascans Materials in Unreal Engine 5
Hello!
I have the same issue as you, I double checked my materials settings with the help of the video and everything was correct even the sampler source, so it wasn’t the magic fix for me
I’ve encountered an issue like this, it wasn’t ideal but I fixed it by rebuilding the landscape, the downside was it affected the sculpting a little bit so I had to go back over a few spots with the sculpting tool
Okay so i manage to fix my tiles but I still don’t have a solution yet,
I did some test on clean areas to see if there was a maximum of material that I could layer before breaking, apprarently not, however three of my materials were actually causing the issue and the issue was fixed once I erase those specific materials on my broken tiles.
I checked the Landscape material but they seems fine, so I have to dig why thoses materials were causing the issue..
So @Thunderloud777 perhaps you also have one or two specific material layers in your landscape material that are causing the issue, you could make a test on a clean area to see if you have the same thing as me
i’ll keep you posted if I manage to find what breaking those material layers
Ok so i found the solution for my problem but as our material is set differently IDK if it will be the same solution:
for me the issue was coming from the Height info, I used the displacement Map for texture where I didn’t have a Height map, and it was actually breaking everything, I replaced it with the AO map and all the proxy tiles are fine now. I’ll make a test with a bump map later but for now i’ll stick with the AO map ( don’t forget to Uncheck RGB )
This ended up working perfectly for me, it was exactly the source type that needed to be changed and now everything seems to be working as intended. Thanks a lot mate, truly!
