Molecular Nodes 0.10.4 for Blender 3.2.X

Fixed several bugs in DNA nodes.

Molecular Nodes 0.10.2 for Blender 3.2.X

Fixed some problems with MDA import.

Bug Fixes:

• #51 chain number was off by 1 when importing via MDAnalysis.
• Animate frames node was being created when number of frames was 1 via MDA import, breaking the structure.

Molecular Nodes 0.10.1 for Blender 3.2.X

DNA Nodes has Arrived!

Added a range of nodes for creating procedural DNA.

Tutorials and documentation to come soon.

Bug fixes:

• Fixes import error from #48
• Fixed bug in DNA styling node errors
• added cutoff for DNA curve join node

Molecular Nodes 0.9.2 for Blender 3.2.X

Added additional selection nodes to improve selection math. Also overhauled some of the menu UI when creating nodes.

Molecular Nodes 0.9.1 for Blender 3.2.X

Bug Fixes:

• Fixed biological assembly node for transformations that require translation as well as rotation
• Fixed center on selection node to use position attibute

Molecular Nodes v0.9 for Blender 3.2.X

This release tweaks and adds some more styling (+ a 'Ball n Stick' preset) and a number of new selection nodes to improve the selection algebra.

Bug Fixes:

• Fixed error with with the scaling on biological assemblies that required translation.
• Fixed non-functioning Style Atom node

New Nodes:

• Selection Element Name (first 20 elements)
• Selection Atomic Number
• Selection AA Number
• Selection AA Number Range
• Style Ball and Stick

Also added the boolean math node under Molecular Nodes for ease of access for atomic selection algebra.

Molecular Nodes v0.8.1 for Blender 3.2.X

Bug Fixes;

• Fixed breaking import with elements higher than atomic number 20
• Fixed detection of ligands as different chains on import
• Ensures that node tree is set up for Blender 3.2 import
• Fixed broken EEEVEE atoms node (bumped to v0.8.1)

New Nodes:

• Ligands are now shown on the chain selection node
• Center on selection node
• Improved EEVEE atoms node
• New and improved surface style node
• New and improved ribbon style node
• Added Brownian motion node under animation
• Overhauled the sticks & find-bond nodes
• Added node for more intuitive atom selection (without having to manually delete / separate geometry)

Molecular Nodes v0.7.2 for Blender 3.2.X

Molecular Nodes with refactored nodes internally to work with the newly introduced named attributes in Blender 3.2. From this release onwards it will only be compatible with Blender 3.2+ and the nodes will not work with earlier versions of Blender (such as 3.1.2).

Molecular Nodes v0.5.23 for Blender 3.1.2

Multiple Bug Fixes:

• Fixed custom chain selection node being added #27
• Fixed AA name selection node being added #28
• Fixed alpha carbon selection as part of atomic properties
• Fixed problem where last atom of properties were being omitted, leading to incorrect element assignment to the last atom in the model #25

Update:

• Fixes broken UI not building. Bump version to 0.5.22

Update:

• fixes broken adding of nodes. Bump version to 0.5.23

Molecular Nodes v0.5.20 for Blender 3.1.2

EDIT: Quick fix added to solve the creation of node trees on MD import. Bumped version number to 0.5.16
EDIT2: additional quick fix to solve appending of nodes on import. Bumped version number to 0.5.17
EDIT3: additional quick change: changed default link for animate note from animate to animate mapped. Bumped version number to 0.5.18
EDIT4: quick fix: fixed import breaking when MD import did not detect any chains from topology. Bumped to v 0.5.19
EDIT5: quick fix: added node for interpolating between mismatched frames & fixed multi-append to single .blender file. Bumped to 0.5.20

Additional release for Blender 3.1.2 to enable the beta-testing of additional features for importing MD trajectories like .dcd and .xtc files via the MDAnalysis package.

• Addresses some issues raised in #13 preparing for a Blender 3.2 release, much work still needs to be done.

New Features

• Rework of the Molecular Nodes panel, added clearer categories for type of file import.
• Moved panel to the Scene Properties tab, with optional panel in the 3D viewport enabled via the add-on preferences.
• Import of topology and trajectory files from MD programs such as GROMACS etc, enabled via MDAnalysis package.
• Launch of the documentation website to present more in-depth documentation than is possible with a GitHub README.
• Added node to interpolate between multiple frames that have mismatching number of points. Currently atomic properties are not interpolated between frames except for b-factor.

What's Changed

• Mda import by @BradyAJohnston in #23

New Contributors

• @BradyAJohnston made their first contribution in #23
