This is ProMaterial Combiner. (it does exactly the same that ProMaterialCombiner++ does).

ProMaterialCombiner++ includes:

- Source code.

- Reuse textures to make atlases smaller.

- Batch mode: Combine several objects materials.

ProMaterial Combiner is an editor extension that will combine materials with 1 click. Quick and easy.

Custom shaders?, no worries; the tool works with any shader.

NOTE: If your UVs are outside [0,0-1,1] and you are using textures your combined material will look wrong; make sure your UVs are inside [0,0-1,1] for your objects

NOTES: - 2022.3.27f1+ supported.

- Easy, Just select your object and click combine.

- No scripting required.

- Meshes automatically set up and adjusted.

- Supports any shader (detected automatically).

- Full lightmapping support.

- Your source assets will not be touched.

- Works with colored and textured materials.

- Supports tiled materials.

- Generate prefabs from the combined object.

- Supports skinned mesh renderers.

- Malformed UVs on colored-only materials are organized automatically.

NOTE: In order to combine materials all shaders have to be the same type.
