  • added the maxwellGetCorrelatedColor() MAXScript function
  • assistant materials retain their name when converted to layered materials

Version 3.1.9
  • added support for Max 2016
  • if the time output mode is set to single, Export MXS writes a single frame even if animation is requested
  • pack'n'go resolves missing file paths in the same way the renderer does, before attempting to copy the files
  • the exporter looks for missing IOR files and MXM files in the same way it does for textures
  • fixed: pack'n'go crashed with some types of materials
  • fixed: the hue adjustment parameter was inverted in the bitmap preview window
  • fixed: crash on export when the Maxwell extensions cannot be loaded
  • fixed: the animation setting in the export MXS dialog and maxwellExportMXS command was not taken into account
  • renamed the "appendFrameNrToImg" flag for the maxwellExportMXS command to "appendFrameNr", because it also affects the output MXS file name, not just the image files
  • added support for extra sampling
  • updated the range of the devignetting parameter to match Studio
  • added MAXScript functions for manipulating visibility flags: maxwellGetObjectFlag and maxwellSetObjectFlag
  • added support for UDIM (tiled textures)
  • the MXS extension is always appended to the name of the output scene files, even when they already contain a dot in their names
  • added a frame offset parameter for the volumetric object
  • fixed: clicking the "hide to camera in shadow pass" checkbox could set it to an indeterminate state (checked but grayed out)
  • the environment intensity multiplier is exported to Maxwell so that the value correctly appears in the multilight panel
  • renamed default item in the FIRE window camera menu to make its purpose clearer
  • the material displacement component is exported even when it is disabled, so that it does not disappear when editing a material with MXED
  • fixed: the density parameter for the scatter modifier did not allow decimals
  • fixed: wrong file names for custom alpha channels
  • fixed: crash in Max 2012 when changing a viewport to ActiveShade
  • fixed: crash in some cases when closing the object properties dialog when Maxwell is not the active renderer
  • fixed: viewport slowdown when using many MxLights set to correlated color emission
  • fixed: the range of the emitter correlated color and coating thickness parameters did not match Studio
  • added support for multiple selection in the light linking UI
  • added support for per-material custom alphas
  • decreased the time needed to open the object properties dialog on scenes with many referenced materials
  • fixed: the "use global settings" texture parameter was not set correctly when importing a MXM file
  • fixed: constant density volumetric objects were not exported correctly
  • fixed: floating reflections/shadows were not working when rendering in draft mode
  • fixed: visibility flags were not exported correctly for Max instances
  • fixed: incorrect names exported for Max instances, causing blocked emitters to break if they were instanced (among other things)
