- Fix shadow depth image layout transitions by tracking per-frame old/new layouts. - Update receiver shadow projection to Vulkan clip-depth convention. - Test inverted shadow compare op path (GREATER_OR_EQUAL). - Switch shadow compare samplers to NEAREST filtering for broader Vulkan compatibility. - Expand shadow caster coverage by disabling caster cull filtering in WMO/M2/Character shadow pipelines. - Keep light-space matrix path on stable character-centered framing.
