Epic Games has frozen the Unreal Engine 5 object version enum, a change that will cause new entries to fail compilation and may break builds for developers with custom engine forks.

Like Mover 2.0, gameplay cameras, Metahuman etc.\n\n It's like they will remain stagnant for at least a year.",

There is a content constraint worth knowing before you evaluate it: translucent materials must output their own luminance only, because materials that sample scene color self-composite the background and the resolve adds it again. Refraction and distortion are future work.\n\nUBA's memory watchdog was throttling against the wrong number: Both percentage thresholds were applied to the commit limit rather than to the quantity each came from. On a 274 GB machine the kill threshold sat at 100.9% of physical RAM and could...",
