v3.5.0

New Features

Rendering

  • Added Substrate material system support for the LCC2 pipeline (LCC2 / PLY / SPZ)
  • Added display support for the LCC2 pipeline in Path Tracing and ray-tracing debug views
  • Added Primitive Alpha Holdout support for the LCC2 pipeline, usable for compositing output (component Details > Rendering > Holdout)
  • The LCC2 pipeline supports per-Player / per-SceneCapture LoadMode and RenderMode, as well as ModifyPlayerTransform, working the same way as LCC

Collision

  • Added automatic collision mesh generation for single-file 3DGS models (PLY / SPZ / SOG); the result is cached next to the model for later reuse
  • Added a Clip Collision option so that clipping volumes and section planes can clip collision as well

Loading & Events

  • Added loading and collision state events (OnLoadStateChanged / OnLoadAnimationStateChanged / OnCollisionStateChanged) to obtain loading progress, first-frame load completion, loading animation state, and collision generation state
  • Added a load failure event (OnLoadFailed) that reports the reason when data fails to load

Editor

  • Checks the packaging configuration when a model path is selected, and when the model directory is not included in the package, shows a prompt with one-click add
  • When unlicensed, selecting the Tiled render mode shows a prompt and restores the original render mode
  • Added multi-language localization for prompt text

Bug Fixes

  • Fixed incorrect rendering under LCC2 pipeline orthographic projection
  • Fixed incorrect alpha blending during LCC2 pipeline post-process compositing
  • Fixed residual drawing when LoadMode is OnlyEnvironment
  • Fixed patchy shading on surfaces when LightingScale is greater than 0 in Lit mode
  • Fixed multiple external clipping volumes being intersected instead of unioned
  • Fixed Tiled mode issues: imprecise culling, wrong clip shape after scaling a spherical clipping volume, and the image not refreshing after a change in screen percentage or dynamic resolution
  • Fixed redundant gaussian drawing that increased rendering cost when switching back to the default renderer after using Tiled mode
  • Fixed per-Player / per-SceneCapture LoadMode not overriding the global LoadMode, and SetPlayerLoadMode / SetPlayerRenderMode callbacks not being released with multiple Players
  • Fixed SetSceneCaptureLoadMode / SetSceneCaptureRenderMode having no effect when called in BeginPlay
  • Fixed a crash when loading single-file 3DGS models (PLY / SPZ / SOG) with a relative path (such as one built from Get Project Saved Directory)
