Changelog 2.5.5 patch

Builds (May 29th 2020)


  • Fixed #4584: Crash when unpinning a Mesh Attribute bound to backdrop
  • Fixed #4576: Nodal editor: Crash when selecting a "local position to world" node followed by a "transform" node. In that order.
  • Fixed #4577: Curve editor: Moving multiple control-points at the same time is broken, messes-up everything when moving too quickly
  • Fixed #4602: Project launcher: When a more recent editor version is installed, opening a project tries to open it with the most recent editor by default
  • Fixed #4601: Project launcher: When a more recent editor version is installed, allows to "upgrade" to that version, but cannot apply upgrades and messes-up entire project by effectively skipping all upgrades.
  • Fixed #4569: Editor cache: When opening/building assets, the editor will recursively rebuild the cached asset onto itself, until the baked path becomes too long for the OS, causing unnecessarily deep cache folders
  • Fixed #3918: Content browser save on close: Does not pop warning dialog about writing corelib files
  • Fixed #4599: UE4: SpecularTexture isn't assigned on ribbons/billboards materials when LegacyLit is enabled

  • Fixed #4547: Script node: "float" and "bool" are inverted in script node drop-down buttons
  • Fixed #4564: Effect editor: Effect repeat mode: Going from a 0 to a nonzero repeat delay instantly spawns lots of effect instances.
  • Fixed #4456: Effect editor propertygrid: Doing a Ctrl+X into a numeric inputbox and unfocusing it keeps it to the value that was just cut instead of resetting it to 0
  • Fixed #4558: All 3D viewports: Grid backdrop is broken when hot-switching coordinate systems in the project settings
  • Fixed #4553: JPG loader: Incorrect loading of Grayscale JPEG files, entire image shifted 2 texels to the left

  • Fixed #4525: Crash when closing an effect editor when multiple other effect editors are opened, and rendering is using D3D12
  • Fixed #4524: Crash when hovering timeline tracks in effects where a layer exports an invalid output pin (a pin which is not an event)
  • Fixed #4518: Content browser: Cannot specify filename with non-ascii characters: Says "Invalid filename"
  • Fixed #4518: Propertygrid: When an asset path points to a non-existing asset, opening the browse window to pick a new asset makes it start in a garbage location (usually program files)

  • Fixed #4483: Crash when enabling CustomSortKey + Slicing
  • Fixed #4477: AssetBaker recompiles every effect twice: takes twice as much time to bake as it did in 2.4.x
  • Fixed #4463: Animtrack backdrop: Produces incorrect effect.velocity values
  • Fixed #4465: AnimTrack backdrop: Switching back and forth between different tracks messes up transforms
  • Fixed #4474: IR Panel: "Events" tab does not show event rate for root event when viewed from inside a layer
  • Fixed #4473: 'orientation' types produce warnings when used with discretization paths (for example using the "PreviousFrameValue" template)
  • Fixed #4498: User can create "Output Node" for input value, followed by a crash
  • Fixed #4459: Payload extract node: When extracting an orientation payload, if the payload presence could not be determined at compile time, and the layer was triggered without the payload, would output a invalid orientation instead of the identity orientation.


Changelog 2.5.1 patch

  • Fixed #4405: Nodal editor: Crash when deleting a template while the nodal editor is viewing one of its child graphs more than 1 level deep
  • Fixed #4415: Renaming an asset in the content browser and choosing to patch references misses some refs in files when the uppercase/lowercase mismatches with the filename ondisk
  • Fixed #4419: Timeline: Editing timeline keyframe payloads when paused sometimes updates the sim and resims (as you would expect), sometimes doesn't.
  • Fixed #4422: Timeline: Payload warnings in layergraph do not show actual timeline track name when the event comes from a root event node, says "layer "Track"", instead of "timeline track "ActualTrackName"", which doesn't help
  • Fixed #4454: Nodal editor shows many false-positive info messages "Event ... sends payload ... which is not used by any of its targets"
  • Fixed #4423: VersionControl: Incorrect command-lines called when assets are saved by the dialog-box when closing the last editor window

Changelog 2.5.0

Builds (Mar 30th 2020)


Nodegraph

Nodal editor

  • #4313: Improved error message when a non-existing submeshID is used
  • #4262: Templates: When disabling node, allow specifying which input should passthrough into which output.
  • #4183: Nodal editor search: Keep a list of recent searches & save settings from one editor launch to another
  • #3996: Auto-exporting a property which other properties depend on now makes those other properties visible regardless of the current visibility rules, so you can auto-export them as well if needed.
  • Fixed #4370: Picking colors in nodegraph UI & color-picker is not gamma-correct (fix does not change existing effects, but the colors shown in the color picker now match the colors injected in the graph)
  • Fixed #4396: Renderers: Picking a new feature-set in any renderer node always pops file browser window at project root
  • Fixed #2423: Hard to resize annotate box

New script functions

  • #4232: Expose script function to extract side, up, and forward axes from an orientation: 'orientation_axisSide', 'orientation_axisUp', and 'orientation_axisForward', as well as corresponding corelib helper nodes: 'orientation.axisSide/Up/Forward', and 'orientation.basisVectors', which outputs all 3

Graph compiler & optimizer

  • Fixed #4321: Compiler: incorrect constant-folding and instruction-combination with 'log'/'log2' math functions
  • Fixed #4286: Layergraph payload optimizer: hitting the max iteration count on certain FXs
  • #4240: Optimizer ICB: detect basis vector extraction from effect orientation and combine into simpler effect axis getter
  • #4239: Optimizer ICB: detect rotation of a basis vector by an orientation and simplify into a basis vector extraction from the orientation + a mul


Simulation

  • Fixed #4303: Curve integral in "Spline" mode is incorrect when control-point segments do not have the same length, produces broken CDF curves.
  • Fixed #4401: Curve probability sampling / CDF: When two curve keyframes have the same 'x' coordinate, breaks the CDF and makes it uniform
  • Fixed #4400: Texture sampler: Texture specified through an inline template property are always converted to BGRA8 at runtime and loose all HDR information
  • Fixed #4399: Texture sampler: Cannot sample the density of a texture specified through an inline template property, only works with an actual texture node.
  • Fixed #4391: view.distance() and view.unprojectedAxis() return an incorrect value when no camera views are registered in-engine. They should return +inf
  • Fixed #4390: Curve sampler: Crashes on x86-SSE machines when sampled with a NaN value
  • Fixed #4294: Some orientation helper nodes with nothing wired in produces a NaN orientation (orientation from forward, from up, from forward up, and from axis angle)
  • Fixed #4403: Mesh sampler: Always reformats vertex-buffer when loading effect, even when format is fine. Wastes time for no reason
  • #4172: Sim interfaces: Allow "partial" binding of sim interfaces when not all inputs are needed by the actual implementation

Simulation: GPU

  • Fixed #3997: GPU simulation glitches when starting some effects


Rendering

  • #3967: Unify meaning of "Size" property between planar-aligned billboards and other billboard types: "Size" is now the particle radius for all billboard types. Was previously radius for all except planar, where it was the diameter.

  • Fixed #4235: CPU-billboarding: normals and tangents are not rotated for screen-aligned billboards
  • Fixed #4288: Useless texture fetch for alpha when using an AlphaTest Opaque material
  • Fixed #4385: Bounding boxes: invalid bbox generated when the 'size' of the renderer is negative

  • Fixed #4322: Material editor: huge stall on main thread when launching async shader compilation
  • Fixed #4319: Material editor: huge performance hit when shaders are compiling

Content browser

  • Fixed #4275: Occasional crash on editor startup during asynchronous effect analysis
  • Fixed #4300: Baking/importing assets ignores the list of allowed asset extensions setup in the project settings
