So we have Experimental support in 4.15 !
Who’s tried it so far ? Not sure what the exact requirements are in terms of project configuration - it talks about cvars and a bunch of automatic detection.
The details seem a bit vague but I have two scenes ready to go - they’ve been constructed with out-of-bounds values in mind for HDR display. Also the LG OLED E6 arrived this week so there’s something to display on too !
