Source Engine Collision Tools

Key features:

• Generate Collision Mesh: Creates Source Engine-compliant collision models for selected objects, with optional decimation to reduce model complexity.
• Generate UV-based Collision: Generates collision meshes based on the object’s UV map, with each UV island forming a separate hull.
• Generate Fractured Collision: Uses Blender’s Cell Fracture add-on to create accurate collision meshes for individual props, adding gaps between hulls and controlling the number of hulls with the “Fracture Target” setting.
• Split Up Collision Mesh: Divides selected collision models into separate objects, each with no more than 32 hulls.
• Merge Adjacent Similars: Merges convex hulls with similar adjacent hulls to reduce the final hull count, potentially improving performance.
• Remove Thin Hulls: Eliminates convex hulls that are significantly smaller than others.
• Force Convex: Ensures all existing hulls in selected collision models are convex, particularly useful after using the Decimate modifier.
• Remove Inside Hulls: Deletes hulls that are almost completely enclosed within other hulls.
• Convex Cut: Combines the Bisect and Convex Hull operators to cut the model and convert the pieces into convex hulls.
• Generate Source Engine QC: Automatically generates QC files for collision models, supporting custom QC commands through a QC Override system.
• Update VMF: Updates a selected VMF file by adding any partitioned or split-up collision models that are not already included in the map.
• Export Hulls to Hammer .VMF: Converts hulls in the selected collision meshes into Source Engine brush solids and exports them as a .VMF file for use in Hammer.
