Version 2.1.5

• On Unity 2023.2, when using HDRP and DX12 graphics API, there’s a chance of crash

  • You can temporarily switch to DX11 (assuming you are not using ray tracing)

• On Unity 2023.2, when using HDRP and DX11 graphics API, visualize SDF in smoke will ignore depth buffer

  • It doesn’t prevent you from using visualize SDF, so you can safely ignore this issue

• When Foam is enabled, regions of the liquid that generate foam will use Material 1 for rendering regardless of material settings

  • To work around that you can disable foam or set material 1 parameters to be the same as the main material parameters

• Depending on certain project settings and the presence of other render related render components and/or packages, liquid/smoke rendering may be flipped upside down on Android (also Oculus standalone) and/or iOS builds

  • To work around that, you can add/remove usage of “FLIP_BACKGROUND_TEXTURE” and/or “FLIP_NATIVE_TEXTURES” material keywords in the plugin’s code
  • Enabling rendering downscale with minimal scaling (e.g. .99) can solve the issue with flipped textures. With the performance tradeoff

• When using non uniform scale with Neural SDF, it will be skewed

• On URP, you may get the following error:

  IndexOutOfRangeException: Index was outside the bounds of the array.

  UnityEngine.Rendering.Universal.ScriptableRenderer.SetupNativeRenderPassFrameData (UnityEngine.Rendering.Universal.CameraData& cameraData, System.Boolean isRenderPassEnabled) (at ./Library/PackageCache/[email protected]/Runtime/NativeRenderPass.cs:113)

  • This error is triggered when you exceed the maximum number of allowed URP render passes
  • To work around it remove or disable unused render features in URP settings

• In Unity 2023.2… the OpenXR plugin doesn’t work properly, so the Liquid/Smoke&Fire VR rendering is limited (DX12/Vulkan not supported). The issue occurs in XR plugin versions 4.4.0 - 4.4.1. Possibly this will be addressed by the newer plugin version >4.4.1. To work around this issue:

  • Use Unity 2023.1….. or earlier
  • Use OpenXR plugin version > 4.4.1 ???
  • Use DX11
  • Use Oculus plugin (DX11 only)

• Liquid on Oculus AR capabilities are limited

• When using non uniform scale with Neural SDF, it will be skewed

• When the manipulator’s scale has a 0 value on any axis, it will break the simulation.

• On URP, you may get the following error:
