RVFX Mesh Extractor – Face Selection & Mesh Separation

Mesh Extractor Tool is a fast and simple Unity editor tool for extracting, splitting, and exporting selected areas from existing 3D meshes.

Select mesh faces directly in the Scene View, separate the selected area into a new asset, or split it from the original model without leaving Unity.

Designed for asset cleanup, prop separation, kitbashing, modular asset creation, and quick mesh editing workflows.

◆ Material-Aware Extraction

Mesh Extractor Tool is built to preserve useful material data during extraction.

It supports shared materials, multiple material slots, submesh-based material assignments, and texture crop workflows.

When texture cropping is enabled, the tool can create matching cropped texture assets and generated materials for the extracted mesh part.

This helps separated parts stay clean, organized, and ready to reuse without manually rebuilding material references.

◆ Renderer Support

Supports both MeshRenderer and SkinnedMeshRenderer objects.

This makes it useful for regular props, environment models, characters, equipment, accessories, and other imported 3D assets.

◆ What You Can Do

• Select mesh faces directly in the Unity Scene View

• Extract selected mesh areas into separate assets

• Split selected parts from the original mesh

• Preserve source materials and material assignments

• Work with shared materials

• Handle meshes with multiple materials and submeshes

• Crop matching texture regions for extracted parts

• Generate matching cropped textures and materials

• Export extracted mesh parts for reuse

◆ Common Use Cases

Use this tool to separate props from combined meshes, extract parts from imported 3D models, split environment objects into modular pieces, isolate character accessories, prepare reusable mesh parts, or clean up assets directly inside Unity.

It is especially useful for:

• Prop separation

• Environment asset cleanup

• Modular kit creation

• Kitbashing workflows

• Character accessories and equipment

• Imported model cleanup

• Preparing mesh parts for further editing

◆ Suitable For

Mesh Extractor Tool works well with common Asset Store models, custom imported meshes, modular kits, props, characters, accessories, equipment, and production assets.

Suitable for many genres and styles, including fantasy, medieval, sci-fi, stylized, low-poly, realistic, RPG, action, survival, and environment-heavy games.

◆ Notes

FBX export may require Unity’s FBX Exporter package depending on your export settings.

Results can vary depending on the structure of the source mesh, UV layout, material setup, shader setup, and texture usage.

Texture cropping works best when the source mesh has usable UVs and clearly assigned texture regions.
