Latest fixes

Patch 1.7.2 (11 Dec 2014)

Build: PopcornFX-Editor_Setup_v1.7.2.23389.exe (Latest PREVIEW)

  • Removed unstable experimental 'effect' backdrop that shipped by mistake in v1.7.0 and v1.7.1
  • mesh renderer Mesh renderer : right-click > explode submeshes to descriptors : fixed bug that did not copy the original descriptor's properties to each child descriptor.
  • mesh renderer Mesh renderer : fixed a crash of the ATI/AMD graphics driver when using the unlit 'Solid' material.
  • When viewport size is reduced, perf HUD now adapts to a more compact version.

Patch 1.7.1 (08 Dec 2014)

Build: PopcornFX-Editor_Setup_v1.7.1.23366.exe (Latest)

  • spectrum sampler Spectrum sampler's Audio viewer did not display for attribute-samplers.
  • Various bugfixes and improvements regarding the online packages.
  • Improved project creation from packages.
  • entering a value too large for a float in a numeric or vector property froze a part of the editor UI.
  • Can now drag&drop a .pkkg in the project list to create a new project from it.
  • Texture sampler Texture sampler : now safely renormalizes the RGBA weights used for density sampling.
  • added a bunch of tooltips on the properties of samplers, evolvers, and renderers.



  • Fixed broken textures hot-reload in some cases.
  • curve sampler Curve editor : Fixed broken curves Min/Max limits in linear mode.
  • curve sampler Curve editor : Changing Min/Max limits now correctly refreshes the curve-editor viewport.
  • Fixed newborn particles update miss : fixes some localspace bugs with some evolver spawner Evolver spawner, and localspace bugs with FirstSpawnDelays.
  • Fixed a bug in the script compiler that produced incorrect results when directly initializing a local variable with another local variable of the same type without changing it.
  • Fixed problematic skeletons and animations imports in projects that were setup with an axis system different from the default one (Right-Hand Y-Up)
  • Fixed a bug that caused the editor's framebuffers not to be destroyed when resizing viewports, causing a serious GPU memory leak
  • Texture sampler Texture sampler : Fixed creeping random crash in density sampling mode. Happened whenever the density image had a first row of entirely black pixels.
  • Texture sampler Texture sampler : Now correctly handles entirely black density textures (no density sampling possible, returns original input UVs without performing the density-mapping)
  • Texture sampler Texture sampler : Improved sRGB handling with older DXT-compressed images.
  • Texture sampler Texture sampler : Load times slightly faster, does not allocate an additional pixel-buffer when converting sRGB <---> Linear anymore. Converts in-place.
  • Texture sampler Texture sampler : fixed some random crashes when hot-reloading images
  • Disabled 'if' and loop constructs in scripts : They were not implemented, did not work anyway, and could cause crashes if still used. Will be restored when a stable implementation will be made.
  • Scripts : fixed a bug when assigning a local variable into itself (ie: "float a = 1; a = a;" or "float a = 1; a = a + 0;" or "float a = 1; a = a * 1;"
  • Mesh importer : fixed a memory leak when importing skeletal meshes


  • Improved performance of 3D noise() functions in scripts (roughly 3 times faster)
  • Improved performance of all curve-sampling functions. Up to 12 times faster on PS4/XBOne, up to 3 times faster on all other platforms.


  • Can now preview and sample animated meshes inside the effects editor.
  • BREAK: for triggered Burst Layers, SpawnerScript "SpawnerLifeRatio" now has the expected value (it was the parent particle's LifeRatio). Use "parent.LifeRatio" to get back the old values.
  • evolver attractor Evolver attractor : added an attraction mode where you can specify a max attraction distance and custom falloff.
  • Texture sampler Texture sampler : sample density : can choose which channel to use, and if choosing average (was the default before), can now override the RGB averaging weights.
  • Texture sampler Texture sampler : now takes into account the filter type. Renamed old unused 'SampleMode' into 'DefaultFilter' and added 'DefaultWrap' for more explicitness
  • Spawn scripts : can now only have a 'PostEval()' function, without the need for 'Eval()'
  • All renderers : can now specify a custom 'Position' field.
  • billboard renderer Billboard renderers : can now specify custom 'Rotation' field.
  • ribbon renderer Ribbon renderers : added ligthing and deformation materials.
  • Shape sampler Shape sampler : Added a new 'sampleVelocity()' function, That allows sampling the surface velocity of skinned meshes.
  • New sampler : Text sampler CParticleSamplerText. Use with a full or partial ASCII texture atlas to display particle-based text.
  • New renderer : Sound renderer CParticleRenderer_Sound.
  • Custom command-line to validate the effects (impacts on the 'status' column of the details view).
  • Show Project Settings : You can view or modify properties associated with your project in he Properties window directly from the ContentBrowser.
  • Changed bake dialog : CTRL+B now performs a silent bake without popping a dialog. To access the old bake dialog, use CTRL+SHIFT+B.
  • Particle Attributes : Can now reorder attributes using right click > MoveUp/MoveDown.
  • curve sampler Curve editor : New menu option 'Swap Curves' allowing to swap two curve components. ex, a float3 'xyz' curve will have the options to swap y<->x, z<->x and z<->y
  • Resource Selector : Node properties now display the full resource path in the tooltip.
  • Resource Selector : Added a 'Open file location' menu item when right-clicking on a resource path in the node properties panel.
  • "Save As" now prevents access to file path : We've decided to entirely remove that window in 1.7 and replace it by an explorer dialog.
  • When creating a new effect, if the name already exists, pops back the naming dialog. Avoids having to re-right-click, create new effect, etc...
  • Editor now auto-detects if a curve should be in loop mode.
  • Improved debug editor HUD : added performance indicators to help optimize your effects, in addition to existing memory and overdraw stats.
  • Added new viewport rendering mode : Wire+Shaded
  • New viewer : Audio viewer, when selecting a spectrum sampler


  • AssetBaker can now bake *.pkan and *.pksa files
