Changelog 2.13.0

Builds (Jul 21st 2022)

GPU simulation

  • D3D12 & PS5 GPU simulation overhaul: Optimization & stabilization
  • Fixed #11323: GPU sim (D3D12): Effects using samplers suffer from a significant CPU overhead due to sampler properties being reuploaded every frame.
  • Fixed #11305: GPU sim: invalid CPU particle count when particles die in less than 4 frames
  • Fixed #11190: GPU sim: Prewarm is messed-up
  • Fixed #11188: GPU sim: discretize function is wrong, returns discretize(x-1)
  • Fixed #11187: GPU sim D3D12 & PS5: Shape sampling is broken on some shapes (Spheres & Complex-ellipsoids)
  • Fixed #11186: GPU sim D3D12 & PS5: disassemblePCoords functions & nodes are broken for Spheres, Cylinders, and Capsules
  • Fixed #11179: GPU sim: Incorrect time scales handling
  • Fixed #11173: GPU sim: effect.scale not supported
  • Fixed #11174: GPU sim: effect.axis* not supported

  • #10481: AnimTrack backdrop: Only list meshes with animation tracks when picking an anim track

  • Fixed #4420: Timeline track descriptions are not localized

Nodal editor

  • #7058: Add a togglable legend in node graph to help identify color meaning


  • Fixed #11328: Sending a NaN in the 'meshID' input of a mesh renderer crashes the editor
