Well, after I saw a tutorial on how to export textures from substance painter, I edited my textures and got this result:
It’s not ideal, but it’s quite better.
Instead of just exporting the textures with the default settings, I now export them with the preset for UE4 and get 3 textures, 1 for the base color, 1 for the normal, and 1 for the Metallic, Roughness and Ambient Occlusion. When I import them into UE the settings go this way:
-for the Base color the sRGB checkbox is checked and the compression settings are set to TC Default
-for the normal the sRGB checkbox is NOT checked and the compression settings are set to TC Normalmap
-and for the Mettalic Roughness and AO the sRGB checkbox is NOT checked and the compression settings are set to TC Default
My material looks like this:
, I didn’t have a reflection capture, but now I do.
Also the normal map is 8bit.
Any ideas how to further improve the result?
