Thanks for answer.
I use UE version 4.23.1.
All pictures that I gave except last one are of uassets of your project. UV does not apply here.I didn’t use any meshes there, just opened uassets in Editor viewer and screenshot that. Material asset viewer (image https://i.imgur.com/BVEPms0.png) uses Unreal’s sphere. As far I can see, this is actual artifact of images themself.
I also tried to import HallwayProps into project using older version of UE (4.22.3). Same artifacts are showing in your assets. Unfortunately, I don’t know what could cause it.
I also looked over other assets in your project - I didn’t noticed any other errors, though I didn’t looked in depth.
Considering I paid for your assets, if you do not have these artifacts in your resources, can you sent assets for this directory to me? I cannot really use this ceiling as is.
To be clear, four .uasset files in directory HallwayProps/Materials/Structural/ceilingTile show artifacts for me:
ceilingSquare_4m_x_4m_LP_BaseColor (https://i.imgur.com/FEpkGLu.png)
ceilingSquare_4m_x_4m_LP_Masks (https://i.imgur.com/L5DEwGs.png)
ceilingSquare_4m_x_4m_LP_MRAO
ceilingSquare_4m_x_4m_LP_Normal (https://i.imgur.com/zZ6g2Et.png)
Rest seems to be ok.
Thanks in advance!
