Overview

Release Highlights

Heightmap-Based Ambient Occlusion

With the new Heightmap-Based Ambient Occlusion (Height Map AO), CRYENGINE 3.8.4 introduces a highly efficient option to obtain large-scale ambient occlusion in outdoor environments without the need for any prebaking. In combination with Screen Space Directional Occlusion (SSDO), the Heightmap AO provides additional shading cues to improve the depth perception of a scene. The focus of the technique is on high performance and to make it suitable for Virtual Reality (VR) and consoles (approximately 0.3 ms on PC).

New Rendering Pipeline Profiler

3.8.4 introduces a new unified rendering pipeline profiler, that provides information from various iterations of our previous internal profiling tools in a better and cleaner interface. The profiler can be enabled with r_profiler 1.

  • Fixed: Double appearance of the 'Missing attachment name' warning.
  • Fixed: The next/prev frame keys (',' and '.').

  • Fixed: the display of certain top-level warnings/errors.
  • Fixed: The display of the warning/error icons on closed branches in the property tree.

  • Tweaked: Added and improved many tooltips and warnings (mostly related to the properties within chrparams).

  • Fixed: Crashes because IAction::UpdatePending was called when the action has no rootscope - this happened in a corner case where all the scopes that the action was running on used an inactive scopecontext (for example when the game calls ClearScopeContext on those scopecontexts). Fixed by not calling UpdatePending unless there is a valid active rootscope.
