4.15.1

Hotfix

Fix script compilation error

4.15

Breaking

Ocean inputs will now only execute the first shader pass (pass zero). Before all passes were executed in sequence which caused incompatibilities with URP unlit Shader Graph. This is only a concern to those who are using custom shaders with multiple passes which we believe is very few.

Preview

Add new CPU-based collision provider - Baked FFT Data.
Add portals and volumes to Underwater Renderer (affects both underwater and ocean surface). See Portals & Volumes for more information.
Add Shader API to Underwater Renderer to facilate adding underwater fog to transparent objects. See Underwater Shader API for more information.
Add Albedo Data feature which allows layering colour onto the water surface similar to decals.

Changed

Add new example scene named Examples which contains many mini examples of different features of Crest.
Add new example scene named LakesAndRivers for adding lakes and rivers using splines.
Add support for rendering in edit mode (camera preview and scene view) to Underwater Renderer. It can be enabled/disabled with the fog scene view toggle.
Add CREST_OCEAN scripting defines symbol.
Add Depth Fog Density Factor to Underwater Renderer which can be used to decrease underwater fog intensitywhen underwater. Greatly improves shadows at shorelines.
Add UV feathering option to Flow shaders.
Add Attenuation in Shallows to Dynamic Waves Sims Settings.
Add Shallows Max Depth to Sim Settings Animated Waves as an alternative to having to extend terrain to 500m below sea level to avoid discontinuity issues.
Add Allow No Shadows to Sim Settings Shadows to allow shadows to be enabled/disabled dynamically.
Add Ocean Renderer > Water Body Culling option so the ocean can ignore culling. Useful if using Water Body > Override Material and still want an ocean.
Improve multiple Water Body overlapping case when Water Body > Override Material option is used.
Water Body adds an inclusion to clipping (ie unclips) if Default Clipping State is Everything Clipped.
Add Underwater Renderer support for Water Body > Override Material.
Add scroll bar to Ocean Debug GUI when using Draw LOD Datas Actual Size.
Add support for TrailRenderer, LineRenderer and ParticleSystem to be used as ocean inputs in addition to MeshRenderer.
Un-deprecate ShapeGerstner as it is useful in some situations for adding a small number of distinct waves with high degree of control.
Add Reverse Wave Weight setting to ShapeGerstner for fine control over generated wave pairs.
Double sample count for ShapeGerstner waves to improve quality.
Tidy up wave spectrum inspector by only showing ShapeGerstner-specific controls when editing within a ShapeGerstner component.
Add option (enabled by default) to prewarm foam simulation on load and camera teleports.
Underwater Renderer validates Ocean Renderer material.
Add Debug > Draw Queries to Boat Probes to draw gizmos for queries.
SphereWaterInteraction component upgraded to produce crisp foam-generating waves without creating large displacements. #979
Add new example scene BoatWakes to showcase improvements to SphereWaterInteraction component.
Allow scaling FFT waves on spline (not supported previously). SplinePointDataGerstner has been renamed toSplinePointDataWaves which works for both ShapeFFT and ShapeGerstner.
Add Surface Self-Intersection Fix Mode (advanced option) to control how self-intersections of the ocean surface caused by intense/choppy waves are handled.
Add Maximum Buoyancy Force for preventing objects from having too much force being applied when fully submerged.
Updated all example scenes.
Add support for secondary lights like point or spot to ocean shader. Only supports pixel lights and not vertex lights.

Fixed

Fix incorrect baked depth cache data that were baked since Crest 4.14.
Fix XR SPI (Single-Pass Instanced) underwater rendering for Unity 2021.2 standalone.
Fix Underwater Renderer not rendering on Intel iGPUs.
Fix clip surface inputs losing accuracy with large waves.
Fix waves at shorelines being incorrectly shadowed. #945
Fix shadow bleeding at shorelines by using the Sea Floor Depth data to reject invalid shadows. #947
Fix exceptions thrown for server/headless builds.
Fix exceptions thrown if foam, dynamic waves and shadows all were disabled.
Fix Floating Origin for Shape Gerstner and Shape FFT.
Fix ocean textures popping (normals, caustics etc) when Floating Origin teleports.
Fix collision queries (eg buoyancy) popping when Floating Origin teleports.
Fix ocean scale smoothing on first frame and teleports. This issue appears as the ocean detail being low and slowly becoming high detailed.
Fix shadow data not always clearing.
Fix shadow simulation not recovering after error being resolved in edit mode.
Fix Allow Null Light option on Sim Settings Shadows not working.
Fix ocean tiles not reverting to Ocean Renderer > Material if Water Body > Override Material was used and Water Body was disabled or removed.
Add Time Scale control for FFT (Gravity setting was broken).
Fix underwater rendering when the camera’s culling mask excludes the Ocean Renderer > Layer.
Fix visible “rings” in dynamic wave sim resulting from fast moving objects that have the Sphere Water Interaction component attached. Simulation frequency can be increased to improve result further, at the cost of more simulation steps per frame.
Fix Sphere Water Interaction component not working in standalone builds.
Fix pop/discontinuity issue with dynamic waves.
Fix underwater culling when Ocean Renderer > Viewpoint is set and different from the camera.
Fix several minor exceptions in cases where components were not set up correctly.
Fix possible cases of underwater effect being inverted on self-intersecting waves when further than 2m from ocean surface.
Fix a per frame GC allocation.
Fix ocean input validation incorrectly reporting that there is no spline attached when game object is disabled.
Fix Shape FFT with zero weight causing visible changes or pops to the ocean surface.
Fix Shape FFT waves animating too quickly when two or more are in the scene with different resolutions.
Fix Shape Gerstner weight not updating correctly if less than one on game load.
Fix Shape Gerstner weight being applied twice instead of once. You may need to adjust your weight if between zero and one.
Fix Unity 2021.2 script upgrade requirement.
Fix compilation error if both HDRP and URP packages are installed.
Fix Underwater Renderer high memory usage by reverting change of using temporary render textures.
Fix Underwater Renderer not using Filter Ocean Data for caustics.
Fix ocean input incompatibilities with unlit Shader Graph.
Fix possible “Extensions” class naming collision compilation error.
