Texture Optimization

Hand-made clothing packs are usually bloated and full of textures the game doesn't like — odd sizes, no mipmaps, wrong compression. The Cloth Tool fixes all of that in one action.

What "Optimize" does

Right-click a texture (or a whole item) and choose Optimize. The pipeline:

1. Decode the source texture to raw pixels.

2. Resize to power-of-two — the nearest valid size (256, 512, 1024, 2048…). Ties round down.

3. Recompress to the correct BCn format for the map type.

4. Generate mipmaps.

5. Write the result as a managed .ytd inside <project>/assets/.

The status line shows the before → after size so you can see what you saved.

Auto-format selection

The tool picks a compression format from the texture's content and name:

Texture	Format	Why
Diffuse, no alpha	BC1 (DXT1)	Smallest; alpha not needed.
Diffuse, has alpha	BC3 (DXT5)	Keeps the alpha channel.
Normal map (_n / _normal)	BC5	Two-channel, high-quality normals.
High-detail / override	BC7	Best quality where size allows.

You can override the format per texture if you know better.

The managed assets model

• Imports are copied into <project>/assets/.

• Optimize rewrites the managed copy — your original files are never modified.

• This is what makes projects safe to move, rename and share.

Rule of thumb: optimize everything before you build. It's the single biggest win for pack size and in-game stability, and it clears most Cloth Doctor warnings automatically.

Exporting

Need a texture out of the project? Right-click → Export to DDS, PNG or XML — useful for edits in an external image editor or for building store renders.
