Release Notes

This page lists all features, changes, and fixes by SpeedTree Modeler version number. For more details about the major new features and changes, refer to the What's new page of the manual.

[10.1.0] - 2025-08-18

Features

  • Improved Vertex Color, Vertex Feature, and Displacement painting experience in Freehand mode on Branches and Meshes.
  • Added season properties in Branch, Leaf mesh, Batched leaf, Frond, Decal, and Mesh detail generators.

Changes

  • Added a message to the Tree Window that notifies you when geometry in the scene is disabled in the View menu.
  • Modified the Rules window, so it now stays where you last made edits instead of scrolling to the top.

Fixes

  • Fixed a bug that caused potential crashes when the LOD system was in use in conjunction with leaf collision.
  • Fixed a bug that caused growth animation exports to USD to crash if any frames were empty.
  • Fixed USD metadata exporting.
  • Fixed the frame count when exporting growth and wind in the same cache.
  • Fixed a bug that could cause Alembic growth exports to fail, so spines now display correctly.
  • Fixed UVs in the output meshes of meshes assigned the "Separate" atlas style during the exporting of multiple models into a combined atlas.
  • Fixed a bug that could cause sequence selection on Mesh Helper objects to pick points outside of the chosen mesh.
  • Fixed a crash related to using a single mesh helper to create multiple spines attached to mesh generators.
  • Fixed a crash that involved toggling projector base generator settings during background computing.
  • Fixed a crash that could occur when pressing the space bar during Mesh Helper sequence selection.
  • Fixed trimmed branches, so they now behave correctly in lower LODs.

[10.0.1] - 2024-09-24

Fixes

  • Fixed crash when copy/pasting a material with cutout meshes into a new tree and then trying to edit those meshes.
  • Updated Cinema4D import script.
  • Fixed random garbage UVs from game FBX export.
  • Clip below ground now works in image export.
  • Art Director icons for editing force strength now match the size of the other Art Director gizmos.
  • Fixed a crash that would occur when using the new wind rigging functionality in v10.0.0 on files saved in v9.x.x with vertex edited meshes.
  • Fixed a threading issue related to profile curve evaluation.
  • Fixed crash when removing maps from a material.

[10.0.0] - 2024-08-14

Features

  • Added Mesh helper tools to create spine hierarchies in hero meshes to control and build off of them.
  • Added Vine generator to create vines that hang with gravity and physically interact with their environment.
  • Added Trim brush to adjust the overall shape of the tree directly from the Tree window.
  • Added Shade Pruning option that removes leaves from the interior shaded parts of the tree.
  • Parent curve option evaluation is now based on either the relative position (between "First" and "Last") or the absolute position of a node.
  • Added configurable mesh data packing script functionality available for use in FBX and USD to control colors and texture coordinates.
  • Added Reference generators that allow placeholders in the generation hierarchy to mark spots for new nodes.
  • Added script Rules that control procedural parameters and speed up common modeling tasks within the Modeler.
  • Branch lengths can be clamped to within a given range per generator to help eliminate unwanted outlier branches.
  • Branch radii can be clamped to range to aid in radius control in complex models.
  • Added an option in the arbitrary scene scale tool to scale the model without modifying any size scalars on the model.
  • Added texture packer that keeps all material maps separate.
  • Added neutral gray light preset.
  • Added save as with assets: "Package Tree", which provides an easy way to export the tree with texture adjustments.
  • Added a prompt to get user preference for loading additional assets like maps and meshes.
  • Added a button to the asset bar to reload all maps on material.

Changes

  • The graphical user interface has been totally redesigned.
  • A wide Property bar now displays properties in multiple columns.
  • Crowded generator labels are now offset when selected or hovered over to make them easier to read.

Fixes

  • Clicked materials no longer "stick" in the material asset bar.
  • Fixed uneditable season curve in material set bar.
  • Material set weights now properly influence material selection.
  • Crash and incorrect behavior associated with click-placing targets has been corrected.
  • Cutout editor now removes transparent polygons correctly.
  • Fin generators compute in-place growth correctly.
  • Leaf Mesh generators compute in-place growth correctly.
  • BatchedLeaf generator edits cause leaf collision to compute as expected.
  • "Ignore parent" flag added to BatchedLeaf generators for use in post-compute collision and shade pruning.
  • Fixed crash associated with branch selection in vertex editing mode.
  • Fixed crash on subdivision surfaces with multithreading.
  • Fixed crash when sliding LOD slider with certain decoration LOD curves.
  • Fixed a bug that could cause slight inconsistencies in parent curve lookups.
  • Fixed problems with width/height updating in various places when using scene cameras.
  • Only branches with wind explicitly enabled will factor into wind behavior.
  • Fixed wind strength property in export dialog, to allow "Current" and "Timeline" options.
  • Leaves that fall during season transitions no longer blow in the wind.
  • Force properties with a behavior chosen no longer get their name cut off in the property bar.
  • The "Chaos" parameter now works in VFX as expected.
  • Names/paths saved into USD files are now sanitized to avoid bad characters that could cause crashes.
  • Fixed problems with editing atlas in export dialog.
  • Fixed disappearing progress dialog throughout the export process.
