• Added immersive room-scale locomotion and continuous crouching.
• Added VR laser sights and universal X+Y calibration.
• Support-hand pickup and physical reload state now remain independent across weapon switches.
• Includes accepted material color-space handling, VR damage/effect fixes and the static-prop decal crash fix.
• Hybrid and Turbo launch modes remain available for Half-Life 2 and its episodes. Portal 1 is locked to Hybrid because its Turbo runtime is not release-safe.
