After switching project to 4.15 version, my specular maps are looking a bit different, more bright. I tought it might have something to do with post process, but I haven’t figured out what yet.
If anyone has any info about it, please let me know
Probably either one of these changes.
NEW: COLOR GRADING CONTROLS
The default tonemapper now provides a more film-like color and tone response
NEW: REFLECTION CAPTURE QUALITY IMPROVEMENTS
When you use Reflection Captures, the engine mixes the indirect specular from the Reflection Capture with indirect diffuse from lightmaps. This helps to reduce leaking, since the reflection cubemap was only captured at one point in space, but the lightmaps were computed on all the receiver surfaces and contain local shadowing.
