Max Texture Size

Max Texture Size is the upper limit for the dimensions of the position and normal texture arrays that Bake VAT generates. The toolkit never creates a texture larger than this value on either axis.

Where to change it

Open Edit → Project Settings.
Under the Plugins category, select VertexAnimationToolkit.
Set Max Texture Size from the dropdown.

TIP

The setting is saved per project (Editor Per-Project User Settings) and is applied the next time you bake. There is no longer a popup during baking — the value always comes from here.

What it does

Each baked vertex maps to one texture column, and each animation frame maps to one row. When a mesh has more vertices or more frames than the Max Texture Size, the data is split across multiple slices of a texture array.

Within that limit, the toolkit automatically picks the smallest size that still fits your mesh and animation, so textures are not padded with empty space. The vertex (width) and frame (height) axes are sized independently.

Lower values keep individual textures small, but very large meshes or long animations will be split into more texture-array slices.
Higher values allow everything to fit in fewer slices, at the cost of a higher potential maximum texture size.

TIP

For most assets the default of 8192 is the best choice: it lets the toolkit fit the texture tightly while keeping the slice count to a minimum. Only lower it if you need to cap texture dimensions for a specific platform or memory budget.

Available sizes

8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8 (powers of two).
