SideFX Labs is a testing ground for over 150 tools designed to help you get up and running quicker. The SideFX Labs tools wrap up and release common workflows and create tight integrations with the software you use every day. The tools are developed outside the regular Houdini development cycle which makes them more accessible for testing and feedback.

Originally published as the Gamedev tools, this initiative has been rebranded as SideFX Labs to recognize that artists in different industries often share the same workflows and that these tools can benefit the whole Houdini Community.

To keep up to date on the latest developments, please click on the Subscribe Button for this thread. You'll get a short email every two weeks listing new tools, updates and bug fixes.

To learn more about the tools you can visit the SideFX Labs Overview [www.sidefx.com] page.

Each new tool should have a forum post where you can leave comments and suggestions.

Updates
  • 1.40 (18.0.316) - Maps Baker now has the option of controlling the gamma on the vertex color and diffuse channels as well as properly previewing the normal maps and other material maps if enabled.
  • 1.40 (18.0.316) - Adding Cage Baking to Maps Baker as well as visualization of baking distances
  • 1.39 (18.0.315) - Shelf tool creates the latest version of the Vertex Animation Textures asset.
  • 1.37 (18.0.313) - Updating Substance Material to work with Mantra op references properly
  • 1.34 (18.0.310) - The SkinningConverter now allows for disconnected pieces of geometry to be weighted individually. This produces really good results in cases where you, for example, rip pieces of cloth apart. A new toggle called “Use Mesh Connectivity for Weighting” has been added for this purpose.

Bug Fixes
  • 1.38 (18.0.314) - Fixed ViewportMeasureTool drawable issue. Works again in 18

New Tools
  • 1.65 (18.0.341) - Added a new menu option under the Assets menu that checks all Labs nodes in the scene for any out of date instances. When a newer version of the tool is available in the already installed release of the toolset. (mapsbaker::1.0 vs mapsbaker::2.0). Assets>Check Asset Versions in Scene

Updates
  • 1.75 (18.0.351) - Added the support for just slicing the geometry and not creating bounding boxes on the Multi Bounding Box sop.
  • 1.74 (18.0.350) - Gaea Tor Processor now fully compatible with Top Fetch without having to do any custom work as of Houdini 18.0.350.
  • 1.69 (18.0.345) - SkinningConverter now has an option to weight pieces with specific bones with matching name attributes. This is a change from an earlier version where connectivity was used for this purpose. Using name instead is more robust, and allows users to be specific. An example of a use-case is exporting RBD simulations.
  • 1.67 (18.0.343) - Updating the Substance COP with some new features.
    - Fixed an issue where blends wouldn't work properly with inputs.
    - Fixed an issue where inputs with same labels would conflict.
    - Fixed an issue where the python callback would fail if there was no open 3d viewport.
    - Fixed an issue with the graph dropdown not being able to be set properly
  • 1.66 (18.0.342) - Gaea Tor Processor now uses TIFs as the file format to exchange data between Gaea and Houdini. Also fixed some minor bugs in the export resolution for Gaea. It will now pad to the nearest power of 2 resolution, rather than 2048. This makes processing a default Heightfield (1000x1000) process at 1024 rather than 2048, which is a lot faster. Also updated the shipped presets to work with newer Gaea versions. Please note that this did bump the version of the tool, so any already instantiated nodes of the Gaea tool need to be recreated or their type changed.
  • 1.61 (18.0.337) - Added a Dissolve Middle Edge option after seeing that users usually remove it as the next step in their workflow in the Thicken SOP

Bug Fixes
  • 1.69 (18.0.345) - Fixing cook error on the RC Texture SOP
  • 1.65 (18.0.341) - Fixing OSM Building Node to use the building_levels attribute

  • 1.88 (18.0.364) The OBJ+MTL Importer now also scans subdirectories for referenced files. This means you can now have a “Textures” folder instead of having all files in root folder.
  • 1.84 (18.0.360) Added support for baseColor usage in the Substance SOP.
  • 1.87 (18.0.363) Added ability for the csv exporter to disable the export of a header row or replace it with some custom data.
  • 1.84 (18.0.360) Adding the ability to not set the name attribute on the MultiFile SOP.
  • 1.82 (18.0.358) Added bgeo and bgeo.sc support to Multifile tool.

Bug Fixes
  • 1.91 (18.0.367) SkinningConverter will automatically convert incoming data to geometry. This solves cases where users accidentally plug in polysoup/other data, and assume the tool doesn't work.
  • 1.88 (18.0.364) Set PhysicsPainter pre-sim detanglement collision to a concave solve. This should give much better results, at a slight performance regression. (Does not affect simulation itself, just the spawn location of drawn objects)
  • 1.88 (18.0.364) Group Curve Corners now works regardless of the curve/shape orientation.
  • 1.84 (18.0.360) Fixing display name on Lot Subdivision SOP.

Bug Fixes
  • 1.110 (18.0.387) Fixed some regressions in MapsBaker. Position map is normalized again, Normalmap has proper Y value, Transfering Normalmaps now also look correct. Also flatten UV.z component to prevent strange texture lookups.
  • 1.110 (18.0.387) Fixed an issue in MapsBaker that would cause the tool to think it is dealing with UDIMs for geometry with perfect 0-1UVs instead of 0-0.999
  • 1.103 (18.0.379) Set the precision of a wrangle in Axis Align to be 64bit. This should help with really large geometry. (Like OSM data)

New Tools
  • 1.154 (18.0.481) Added the FBX Archive Import sop. This is a sop built to function similar to the file sop, but with material import support.

Updates
  • 1.156 (18.0.485) Delete Small Parts is now compiled
  • 1.156 (18.0.485) Gaea Tor Processor is now compatible with Gaea 1.2. This is a BIG update, where the bridge now has a revamped cleaned UI, user accessible preset system, r32 map IO, no more remapping, texture support, ability to use with Bleeding Edge builds. This bumped the tool version, so you need to replace existing Gaea Tor Processor instances with a new node to take advantage of it. The tool also does not support older versions of Gaea, but you can use older versions of the tool for that.
  • 1.154 (18.0.481) Added Group option to Auto UV SOP.
  • 1.154 (18.0.481) Adding an option to link an external COP into the substance Material, this allows for the Substance Material to support input maps.

  • 1.153 (18.0.479) Add parameter to the static fracture export to delete existing container.
  • 1.153 (18.0.479) Adding a accuracy parameter that increases the resolution on the internal remesh node to handle pipe like meshes better.
  • 1.152 (18.0.475) Removing built plugins from Labs.

Bug Fixes
  • 1.156 (18.0.485) FBX Archive Import now properly supports skinned meshes import

New Tools
  • 1.157 (18.0.492) Added Group by Measure .This tool will feature a lot of options to group geometry based on measured properties. Currently limited to Eccentricity (squaredness) of primitives.
  • 1.157 (18.0.492) Added HF Combine Masks. This tool allows you to very easily do some layering logic to create useful masks. Ex: Create a new layer that is everything except grass layer, water layer, tree layer with a simple multiparm. No need to create multiple HF Layer nodes anymore.

Updates
  • 1.159 (18.0.494) Added Unreal content plugin for 4.24
  • 1.158 (18.0.493) RBD Fracture, Simple RBD, RBD Solver, RBD Director are now DEPRECATED. All functionality of these nodes has been implemented into the new RBD Material Fracture nodes and others, and are therefore no longer needed. As usual, nodes are hidden for backwards compatability but will be removed in future updates.
  • 1.158 (18.0.493) VoxelMesh will now throw a warning if you feed it open geometry
  • 1.158 (18.0.493) Niagara Interpolate is now DEPRECATED, and therefore hidden. It is still part of the toolset and work with existing files to be backward compatible, but will be removed in the future.
  • 1.157 (18.0.492) Major update to Vertex Animation Textures ROP including a Unity package with shadergraph materials for URP and a content plugin for Unreal. Please refer to the node's documentation for more details.

Bug Fixes
  • 1.157 (18.0.492) Fixed a regression in Gaea Tor Processor that would cause changes to the parm interface to not recook the graph.

New Tools
  • 1.168 (18.0.506) Added Ruler to the toolset. This is a nodeless python state accessible from the labs shelf menu. It allows for the user to make interactive measurements in the viewport on currently displayed SOP geometry.
  • 1.165 (18.0.501) New Star SOP allows you to make Star shapes easily
  • 1.164 (18.0.500) Added Dem Bones Skinning Converter to Labs. Dem Bones Skinning Converter is a tool from EA that can convert any non-changing topology deforming mesh sequence into a bone based animation. For more information see https://github.com/electronicarts/dem-bones [github.com]
  • 1.160 (18.0.495) Added Mesh Sharpen. The Mesh Sharpen tool sharpens the geometry based on the curvature found on the mesh. It does so by pushing the points on the mesh towards the higher curvature regions, therefore “sharpening” those regions. This tool is a community contribution from Jake Rice - @TearsOfJake
  • 1.159 (18.0.494) Added HF Insert Mask. This tool quickly allows you to insert a mask from a second heightfield into your primary heightfield.

Updates
  • 1.169 (18.0.507) Ruler tool now supports undoing with Ctrl-Z.
  • 1.168 (18.0.506) Pyro Preview ROP has now been DEPRECATED. The default viewport shader has caught up with the Mantra Render to no longer need this tool. As usual, the tool will still be available to those who are using it / need it.. Just hidden. It will get removed in the future.
  • 1.163 (18.0.499) If no composite view exists when attempting to Set Composite View on the Texture Sheet ROP a message will be displayed.
  • 1.163 (18.0.499) FBX Archive Import now properly handles hierarchies of geo nodes with materials assigned on the obj level.

Bug Fixes
