Hi,
I upgraded my project from UE4.26 to 4.27 (both source build) and within the editor everything looks identical to 4.26.
However once I build a standalone game in 4.27, everything gets overly shiny and a ‘wet’ look.
Textures are correctly setup, MRAO maps have sRGB turned of and no matter how I change compression and texture profiles. It’s always broken.
I also tried to compile a newer in development version of UE4 but with the same result.
Does anyone know a solution to this?
Thanks
Do your materials have any sort of switches or possibly textures which failed to pack (Roughness for the skin)?
Switches as in both scalability/shader level.
The log does not indicate any issues with packing any texture. Yes some Materials have quality switches and others not. all of them suffer the same issue.
It could very well be a project issue.
Try to plug a mesh in there with different parts of the same texture.
Doesn’t much matter what it is, just output each texture into the albedo in 4/5 copies of the mesh.
Use a texture that is already on screen - like the skin or the AK.
Package, and test to see if you get all the textures to show up or what happens.
You’d expect all of them to show - but if doing this gets the other mesh to look correct there’s some problem with loading assets or similar.
Also, the settings you “play” with should probably be used to test when you play in editor.
Full screen, ray trace, whatever else your game settings in the published project that’s not working right are could possibly be part of the problem.
Other than that, haven’t ran into this particular issue so far. If you use PAK files for memory saving, make sure they aren’t srgb.
When they are, stuff is more glossy as the colors are off. But never seen it to the point of your screen-shot.
I ‘fixed’ the issue. It seams like it was an issue with the project conversion. It was initially a UE 4.24 project updated to 4.26 and now to 4.27. If I convert the project from 4.26 to 4.27 the project has the visual issues + does no longer run on consoles.
I created a new, empty UE 4.27 project and copied just everything over from the 4.26 project and it works just fine. Seams like the conversion process has some issues with older projects.
I have the same issue, I followed PolygonArt’s fix above (new project as mine was also and upgraded 4.26 project) this did not correct the issue. It must be related to a project setting however that setting must have an impact on 4.27 materials. Any one with any insight please do respond to this message!
