SPA Materials Baker >>>> Complex in. Simple out. (V2)

SPA Material Baker is a production-ready material baking tool for Unreal Engine that converts complex shaders into optimized, game-ready textures with simplified materials— directly inside the editor.

Bake procedural, layered, or world-aligned materials into clean texture maps with full control over UVs, materials, and batch workflows.

✨ Key Features (V2)

Advanced Material Baking

Bake full PBR textures from complex, layered, and procedural materials.

Static & Skeletal Mesh Support

Works seamlessly with static meshes, characters, and animated assets.

Automatic Material Workflow

Auto-create materials, instances, and assign textures in one click.

Auto Master Material

Instantly generate a fully configured PBR master material.

Smart Material Instances

Automatically create and assign clean, organized material instances.

Auto Assignment

Apply baked materials directly to meshes or actors instantly.

Powerful Batch Baking System

Process multiple meshes and materials with production-ready workflows.

Custom Pass System

Bake extra maps like displacement, opacity, and custom data outputs.

Packed Texture Support (ORM)

Pack AO, Roughness, and Metallic into a single optimized texture.

UV & UDIM Support

Supports tiled, overlapping, and UDIM-style UV layouts.

World Space Baking

Bake world-aligned and triplanar materials with accuracy.

Material Index Control

Bake specific material slots or entire mesh materials easily.

Quality & Optimization Controls

Fine-tune output with advanced quality and texture settings.

💡 Typical Use Cases!

• Convert complex materials into optimized texture sets

• Bake procedural or layered shaders into stable outputs

• Prepare assets for:

  • LODs

  • Mobile / VR

  • External pipelines (Substance, Unity, etc.)

• Reduce draw calls and shader complexity

• Generate clean, portable materials for outsourcing or marketplaces

• Bake character and environment assets in bulk

! Limitations

• UE5.7 uses a different internal material baking algorithm — in some cases, baked results may differ from other engine versions

• Dynamic materials must use local/object transform space to bake correctly

• Overlapping UVs and UDIM-style layouts may not produce correct results in some cases

• Currently uses a simple generated material for baking in certain scenarios

• Opacity is not supported in standard baking workflows

• Custom passes share AO output (mutually exclusive)

• Supports UDIM-style UVs (single atlas output only)

• Landscapes and decals are not supported

Very high-resolution batch baking may require significant memory


⚠️ Compatibility Note: Substrate materials are not supported in the current version.
For stable results, ensure Substrate is disabled in your project settings before baking.
