Source Engine Collision Tools

Changelog

• Rewrote the "Remove Thin Hulls" operator

• Added two new operators: "Merge Thin Hulls" and "Find Thin Hulls". These two new operators give users much more flexibility with how they choose to deal with thin hulls.

• Updated all operators so that they behave more consistently when multiple objects are selected and the active object happens to be a non-mesh object (ie. a light). The operators will now ignore non-mesh objects if they happen to be the active object, and instead will default to setting the first mesh object as the active object after the operator runs.

Changelog

• New "Count Hulls" operator - counts hulls without modifying them. You can find it under the Cleanup subpanel.
• Better error checking when accidentally using the operators in Edit Mode
• Fixed bug where some operators were unintentionally altering the object's origin point
• Improved consistency for selected objects staying selected (or active, if previously active) when using any operator on them
• Various fixes for the Split Up Collision Mesh operator, with improved error checking
• Rearranged the Force Convex button to be higher up in the subpanel, due to its high frequency of use

Changelog

Bugfixes:

• Fixed bug that occured when Merge Adjacent Similars was used on a parented object. The resulting collision was being rotated incorrectly due to the parent.
• Fixed bug in the "Generate Collision via UV Map" operator that was triggering an error if used on a mesh with no UV map

Changes:

• After generating collision via any of the available methods, the resulting collision meshes are now set as 'selected' automatically.
• The UI has been generally improved and reorganized for improved usability. Among those UI changes are the following name changes below:
• Renamed "Generate Collision Mesh" operator to "Generate Collision via Faces"
• Renamed "Generate UV-based Collision" operator to "Generate Collision via UV Map"
• Renamed "Generate Fractured Collision" operator to "Generate Collision via Fracture"
• The "Generate via Fracture" method now actually reads and uses the Decimate Ratio setting. It was previously the only 'generate' method that didn't use it.
• The addon's UI is now organized into 3 collapsible sections - Generate, Cleanup, and Compile. When you're only using one set of these tools, you can simply hide the others now for better usability.

New features:

• Added new operator - Generate Collision via Bisection. This is a new method for generating collision which uses the Bisect tool behind-the-scenes to automatically slice up the model in a grid-like fashion. It's incredibly effective for individual prop and character models. For large scenes, I would recommend separating specific sections of the scene and then using this new operator on individual parts only, not the entire scene at once.

Changelog

Fixed crash that would occur when trying to undo the Generate Fractured Collision operator

Changelog

-Fixed crashing when attempting to undo collision operators. -Fixed issue causing pivot point to always be set to Individual Origins after the Generate Collision Mesh button was pressed.

Changelog

Added "Game Engine" tag and fixed permissions, now correctly reflecting the Files permission, in the blender_manifest.toml file.

Changelog

Removed lines that modify sys.path and modified the PyVMF module filenames so that it works without requiring sys.path modification.https://extensions.blender.org/download/sha256:295937caf09fdb6022f30a64f34b1bb64713e46aca123e83162e59b1cfc48c38/add-on-sourceenginecollisiontools-v1.4.3.zip?repository=%2Fapi%2Fv1%2Fextensions%2F&blender_version_min=4.2.0

Changelog

v1.4.2: Replaced the old method for checking if the Cell Fracture method is installed. The previous method only checked if the addon was installed, but didn't check if the addon was actually enabled after installation. Now the Generate Fractured Collision operator will exit gracefully if the addon is not enabled.
