I’ve always suspected this to be the case but I’ve finally gotten around to thoroughly test it.
This is easily reproduceable. Take any image. import into UE4. Then make a material with OneMinus node. Then invert the texture in photoshop and import.
A texture sample that is being inverted in Photoshop differs from one minus. I have tried this on multiple texture.
Hi ,
It happens cause gamma correction, Uncheck sRGB property in your textures.
Hope it helps!
i read about this as well… i initially tested it by removing sRGB on the origina texture and still differs from the inverted ( in photoshop ).
however when i removed sRGB on both the interverted ( in photoshop ) and uninverted . It does bring the same value.
I guess this is correct. sRGB does cause gamma correction. Thank you.
