I noticed the same in ShooterGame where the roughness reflections appear red. I have made no changes between a working version in 4.7 and this result in 4.8. (Also notice the edges of the shadow.
Turns out this is something new since 4.8 in Post Process volumes. You can observe the same error in ShooterGame. Toggling unbound property in my post volume toggles this error, I can’t find the source of it though so it doesn’t appear to be a manual setting that broken.
Thanks for the report. We have a report in for this bug already as UE-16192. The red reflections are caused by the new tonemapper specifically the Color Grading LUT, if you disable LUT the reflections should be removed. We are currently working on a solution to this issue.
i agree , problem its in settings of texture (postprocessing , color grading) becouse ue4.8 i don`t know why, changing some settings of Texture, my solution, go to the settings of texture from color grading, and change parameters manual like on screen
Thanks for this dev666rej! I just would like to know if this is will be an issue to be fixed or just a workaround from Epic since I have a product soon to be released on the marketplace and it’s entirely based on LUTs.
We are still loooking into the issue, but in the meantime as long as your LUT textures are correctly set to use NoMipMaps, Assigned to the ColorLookUpTable Texture Group, and do not use sRGB, there should be no problems in your projects.
