  at startup.

Nodes

• Shader nodes can now be variadic, i.e. have a number of parameters, inputs and outputs that
  are repeated. A new icon in the node titlebar shows the variadic aspect and can be used to
  increase or decrease the number of occurences of those parameters and ports.
  A few nodes have been updated accordingly, so Blend now supports several layers,

Miscellaneous

  Although it has a lot of limitations, it is a good way of trying Material Maker without
  installing it.
• Self-connections of subgraphs are now allowed if they don't form a loop, and loop
  detection has been optimized (contributed by myaaaaaaaaa).

Material Maker 1.1

General

• Updated renderer to limit the size of rendering viewports (big textures are rendered in chunks and reassembled).
  This can be used to avoid crashes on lower end GPU and/or when generating high resolution textures. The maximum
  render size can be configured in the progress counter context menu.
• Added GPU memory information near the progress counter, with a tooltip that shows the GPU interface name (this
  can be used to know if Material Maker runs on the integrated graphics on a laptop).
• In Graph views, added support for arrow keys to scroll in all directions (useful when connecting nodes that
  are far from each other).
• Buffer nodes and nodes that contain buffers are now shown with a specific icon. Right clicking that icon
  show a context menu that can pause and resume the buffers (making it possible to disable useless rendering
  of parts of the material).
• The FPS counter, the GPU memory counter and the rendering progress bar have been moved to a status bar at
  the bottom of the user interface.
• Added a small icon in the status bar that shows the status of the clipboard (and if it can be pasted into
  a graph view).

  Unity engine) when re-exporting materials.

  and node parameters, and added more shapes and operators.

  as soon as 2 consecutive results are identical.

  and input of the Fill companion nodes.
• Removed the Iterations parameter from the Fill node, and added parameters to remove the edges and adjust
  the generated bounding box.
