CHANGE LOG

Alpha RC 0.0.2

Fixes

  • Quite a bit of fixes in math nodes
  • Quite a few null reference exceptions taken care of
  • Quite a few fixes in other nodes
  • Fixed issue in blend glsl with alpha not working as expected and adding masking
  • Fixed depth.glsl
  • Various other fixes that I lost track of...

Additions

  • SSS now available in the PBR shader via Thickness map
  • You can now see the light source and reposition it
  • You can now modify some material settings such as height, SSS, refaction index, etc.
  • You can now load custom preview models (They are not saved with the graph currently)
  • You can now export and import function graph nodes via right clicking the graph when in the function graph
  • You can now add custom variables and custom functions
  • Graph instance parameters can now be promoted as well
  • Keyboardd shortcuts added for save (ctrl-s), undo (ctrl-z), redo (ctrl-y), copy (ctrl-c), paste (ctrl-v), add comment (c key), add pin (p key), and next pin navigation (tab key)
  • Popup shelf added - can be accessed via space bar when focused in graph area
  • FXNode added, not quite as powerful as substance's, but getting there
  • New graph dialog added
  • App icon created and added
  • You can now resize multiply nodes at once via the toolbar in the graph
  • You can now add comment nodes and pin nodes. Double click a pin node to set color. Double click header of comment to set comment.
  • Added logging and a log window

Changes:

  • Various UI improvements
  • Underlying code restructure for some areas
  • Graph instances now keep track of the parameter values differently (Your old .mtg file will not load the pre-existing variables of a graph instance)
    • This was done to save file space and eliminate duplication of data
  • Other various changes here and there that I lost track of...

Pre-Alpha 0.0.1

Fixes

  • Fixed several crashes related to null checks
  • Fixed Function Graph shader generation improperly generating shader code in the wrong order
  • Fixed graph file missing its width and height properties when saving and loading
  • Fixed crash when closing a tab that was not the active tab
  • Fixed copy and paste not working on graph instances
  • Fixed issue where graph instances within graph instances would fail to connect to their input nodes
  • Fixed issue where graph instance width and height was not proportionally scaling
  • Fixed some other bugs in graph instances
  • Fixed issue where graph instance properties would not show up correctly
  • Fixed issue where labels for graph input and outputs were in the way of the node connection
  • Fixed issue where shelf UI would not populate from Shelf folder
  • Fixed missing GetJson and FromJson for several nodes
  • Fixed issues with various blend modes on the blend node
  • Fixed blur.glsl; it had a missing + 1 on the averaging part.

Additions

  • Most nodes can now promote a property to constant (for graph instance access) or promote to a function graph
    • The following are predefined variables for a function graph: (Float2)pos (Only usable in PixelProcessor Function Graph), (Float2)size, (Float)PI
    • Variables are case sensitive
    • A promoted property function graph also has access to the other properties on the node, except if the other property is promoted to a Function
      • If the property has a space in the name, then the variable name will have no spaces
  • The float value of the float constant math node now can be promoted to a constant or function as well (other math nodes that have constant values will be added later on with more testing).
    • By promoting this to a constant, it can be modified as a graph instance property.
  • You can now change the current 3D Hdri lighting of a graph via Edit -> Graph Settings
  • Included some more complex example graphs in the Example folder (Note these graph will only work with these latest changes due to various bug fixes etc.)
  • Added filters for Curvature from Normal and Curvature Smooth from Normal
  • Added simple search to shelf
  • Added Gamma node

Changes

  • Various rewrite for 3D preview and some classes

Known Issues:

  • Undo and Redo seem to be borked in some cases
  • Panning of the 3D object in the 3D preview is still borked
  • When loading a PixelProcessor function graph, the view is not properly updated sometimes.
    • The work around for now is to hit the actual size button to reset the view to 100% zoom.
