Why we like it

Stands out in the Superhive library for combining collision generation and game-asset export in a single Blender N-Panel.

What is Grs Game Tools: Auto-Collisions & Smart Fbx Exporter?

GRS Game Tools: Auto-Collisions & Smart FBX Exporter combines a collision generator and a smart FBX exporter into a single Blender workflow, accessible from the N-Panel. It targets game developers and 3D artists working with Unreal Engine, and its interface is localized in English, Spanish, Chinese, Japanese, and Russian.

On the collision side, a Top-Down Slicer algorithm generates optimized, merge-ready UBX pillars for complex environments such as stairs, walls, and caves, without the performance cost of Convex Hulls. Auto-Primitive Detection mathematically analyzes a selected prop's volume and assigns a UBX, USP, UCP, or UCX collision type based on custom fill-ratio tolerances.

The export side offers one-click Smart Batch Export directly to an Unreal Engine folder, covering static meshes, skeletal meshes with automatic UE5 root-bone fixes, Groom/Hair Alembic files, and textures. Dynamic UVs by material unwrap each material slot separately to maximize Texel Density, while hierarchy and sanity checks handle child meshes and flag missing UVs, materials, and weights before export.

Frequently asked questions

Does GRS Game Tools support languages other than English?

GRS Game Tools ships with interface localization in English, Spanish, Chinese, Japanese, and Russian. That covers the labels and controls in its Blender N-Panel across all five languages, so the collision and export tools can be operated in whichever you prefer. Both the collision generator and the smart FBX exporter live within that same panel. For confirmation of the current language list and any additions, check the developer's page on Superhive.

What collision types can GRS Game Tools generate?

GRS Game Tools can assign UBX, USP, UCP, or UCX collision types. Its Auto-Primitive Detection mathematically analyzes a selected prop's volume to pick the collision type automatically, based on custom fill-ratio tolerances. Separately, the Top-Down Slicer algorithm generates optimized, merge-ready UBX pillars for complex environments such as stairs, walls, and caves, without the performance cost of Convex Hulls. For details on how each collision type behaves, see the developer's page on Superhive.

Can GRS Game Tools export skeletal meshes to Unreal Engine 5?

GRS Game Tools handles skeletal meshes as part of its one-click Smart Batch Export, applying automatic UE5 root-bone fixes during the process. The same export also covers static meshes, Groom/Hair Alembic files, and textures, sending them directly to your Unreal Engine folder. Before export, its sanity checks look for missing UVs, materials, and weights so broken assets are caught early. To confirm exact supported Unreal Engine versions, check the developer's page on Superhive.

Is GRS Game Tools free to download?

GRS Game Tools is listed as free in this catalog. Pricing and licensing can change, so for the current terms and any download conditions, check the developer's page on Superhive. The add-on packages both a collision generator and a smart FBX exporter into one Blender N-Panel workflow, with interface localization in English, Spanish, Chinese, Japanese, and Russian. Reviewing the developer's page also confirms the latest feature set and language support.
