Your edges.
Your direction.
Guide edges with direction constraints. Lock an island’s position, rotation, scale or shape while working on the rest.

THE WORKSPACE
See the whole picture.
Shape every detail.
Your mesh and its UVs, side by side.
Move between the big picture and the edges that matter.
Your edges.
A shape worth
getting right.
Build UVs from your seams, refine them with Optimize, then explore contour deformation and interior UV alignment.
Pick up where
you left off.
Save your workspace as a project. Import binary FBX and export your edited UVs with the original 3D geometry preserved.
BLENDER BRIDGE
Out of Blender.
Into your flow.
And back.
Send selected meshes from Blender to Alpaca3D. Work on your UVs, then return them to their source UV maps.

A FEW DETAILS
Before you begin.
Do I need Blender to use Alpaca3D?
No. Unwrap, Optimize and Pack work inside Alpaca3D. Import a binary FBX file to get started. Blender is needed only when using the optional Bridge workflow.
How do I start using Blender Bridge?
Install the add-on from the Blender Bridge folder included with Alpaca3D, and select the installed Alpaca3D application in its settings. In Blender Object Mode, select meshes with an active UV map and send them to Alpaca3D. Return the edited UVs to the source maps when ready.
What can I import and save?
Import and export binary FBX (7000+), or save a JSON project to continue editing later. Packing uses the 0–1 UV tile; UDIM and ASCII FBX are not supported.
