surface filler

“Fill Model” Brush

This brushes does the same thing as the surface-fill brush, but for all surfaces of the model at once.

Sticker Tool

This tool lets you add 2d assets to a UV-unwrapped[1] model like stickers:

adding a sticker

[1] a 3D resource with no UV data will not be able to receive stickers. UV unwrapping is on our backlog, but until then, use blender or another tool to save the resource with UV data.

Notice the tool shows details of the stack of stickers currenlty applied on a model when it’s clicked:

Stickers can be shown/hidden, renamed, moved up/down the stack (higher means it’s displayed “on top” of others), removed, and locked. A locked sticker cannot be manipulated.

Manipulations

To manipulate a sticker, use the mouse:

  • left press + release (without moving): select the sticker

  • left click + drag: move the sticker on its surface (a sticker cannot move from its original surface to another)

  • right click + drag: rotate

  • mouse wheel: scale

Export

When exporting the asset, GAC blits all stickers onto a single texture applied to the mesh.
