Node Arrange

Changelog

Fixes

• Fixed an issue where nodes could have unbalanced vertical positions in node trees with frames.
• Fixed an issue where unnecessary link overlap could be created.
• Fixed an issue where frames could overlap.
• Fixed an issue where the bounding boxes of frames could be unnecessarily wide.
• Fixed various issues with link routing.

Changelog

Improvements

• Nodes in frames now have balanced vertical positions.
• Reroutes linked to multiple outputs now align with other reroutes in node trees with frames.
• Reroutes now pick better sockets to align with.
• Nodes now preserve their original vertical order where possible.

Fixes

• Fixed an issue where frames with nested frames could intertwine.
• Fixed an issue where an error could be given with multi-inputs.
• Fixed an issue where an error could be given when arranging nested frames.
• Fixed an issue where the spacing between frames could be too small.
• Fixed an issue where reroutes could be misaligned with sockets.
• Fixed an issue where unnecessary crossings could be created with frames that have only reroutes or frames as children.

Changelog

Improvements

• Links from the same output are now merged, giving a major boon to readability.
• Recenter Selected and Recenter Node Trees no longer cause node trees to be re-evaluated.
• Crossing minimisation is improved.
• Less unnecessary reroutes are created.
• The additional height added by frame labels is now accounted for.

Fixes

• Fixed an issue where the order links in multi-inputs could be changed.
• Fixed an issue where increasing/decreasing Spacing X could have the opposite effect.
• Fixed an issue where an error could be given with nested frames.
• Fixed an issue where reroutes with custom labels could be removed.
• Fixed an issue where reroutes could be misaligned with inputs if unconnected sockets are hidden.
• Fixed an issue where an error would be given if Spacing X is set to 0.
• Fixed an issue where an error would be given if a frame with only reroutes has a segment with an unconnected input.

Changelog

Fixes

• Fixed a regression where unnecessary link overlap could be created in and around frames.
• Fixed an issue where operators were able to be invoked outside the sidebar under incorrect conditions.

Changelog

Fixes

• Fixed an issue where the hotkey for Recenter Selected wouldn't work.

Changelog

New

• Added Arrange Node Trees for batch arranging all node trees in the .blend file.
• Added Recenter Node Trees for batch recentering all node trees in the .blend file.
• Added a new option for Recenter Selected for setting the origin of the node tree.

Improvements

• Reroutes now move left of nodes more to prevent obscured links.
• "Clear" has been renamed "Recenter" in the UI.

Fixes

• The sidebar tab no longer shows when there's no node tree in the editor.
• All operators are now disabled when the current node tree is linked from another .blend file, or undefined.

Changelog

Fixes

• Removed an old debug UI element that would fail to load.

Changelog

Improvements

• Nodes are partitioned into 'columns' better, giving multiple knock-on improvements:
  • Layouts are more compact.
  • Less reroutes are produced.
  • Crossings between links are reduced.
  • Nested frames now always reduce their parent frame's bounding box.
  • Up to 1.6x faster.

Fixes

• Fixed an issue where frames could intertwine.
• Fixed an issue where unnecessary reroutes, extremely close to outputs, could be created.

Changelog

Improvements

The arrangement logic has been completely overhauled:

• Links are now routed around nodes, dramatically improving readability.
• Crossings between links are now significantly reduced.
• The vertical placement of nodes has been improved.
• Node trees without an output node can now be arranged.
• Unused nodes are now arranged.
• Additional horizontal spacing is now added to prevent steep links.
• Nodes in a column are now centered horizontally.
• Arrange Selected now centers the new arrangement with the old center of selected nodes.
• Clear Locations now uses the center of the selected nodes to get the difference from (0, 0), if there's no selected active node.

Fixes

• Fixed an issue where Clear Locations would fail when there's no active node.

Changelog

New

• Clear Locations
  This operator moves the active node to (0, 0), and other selected nodes with it.

Changelog

Fixes

• Fixed an issue where Blender would hang on invalid links.

Changelog

Improvements

• Two nodes linked singly to each other now always align.
• Nodes linked singly to each other are now positioned better vertically.
• Unframed nodes with no nodes above them now always align.
• Image textures linked to principled BSDF and displacement nodes are now ordered better vertically.
• Frames now stack above/below other nodes and frames better.

Fixes

• Fixed an issue where nodes could be excessively far down.
• Fixed an issue where frames wouldn’t be centred horizontally.
• Fixed an issue where nested frames could move beyond their descendant nodes.
• Fixed an issue where frames could overlap with unframed nodes.
• Fixed an issue where nodes could be in the same X location as their successors.
• Fixed an issue where reroutes could be obscured behind nodes at higher UI scales.

Changelog

Fixes

• Screen DPI is now accounted for.
• Resolution scale is now accounted for.

Changelog

Fixes

• Fixed an issue where nodes could be slightly vertically misaligned.
• Fixed a rare issue that could cause Blender to hang.

Changelog

Improvements

• Nodes linked singly to each other now align much more often.
• Nodes now better minimise the vertical lengths of their links.
• Frames now better minimise the vertical lengths of their links to non-children.
• Up to 1.3x faster.

Fixes

• Fixed an issue where nested frames could move beyond their descendant nodes.
• Fixed an issue where frames nested more than 1 level deep could have excessively spaced out children.

Removals

• Options for Adjust Vertical
  Despite the name, these options only dealt with a small number of vertical adjustments. They’ve been removed to minimise confusion, and because the non-defaults gave poor results.
