Create with control.
Extend your mesh with Create, shape loops with Contours and Strokes, then refine edges with Knife, Loop Cut and Fill.

ALPACA3D
Your next asset.
Taking shape.
Build the topology. Shape the UVs. Bake the detail.
Three labs.
One Alpaca.
From the first polygon to the final texture maps.
01 / RETOPO LAB
Give every polygon
a purpose.
Build a low-poly mesh over your reference. Place the topology where the shape needs it, with tools that keep you close to the surface.
Stay on the surface.
Snap to reference geometry and refine the silhouette with Move and Relax brushes. Use symmetry to work across matching sides.
Keep your mesh moving.
Move between Retopo and UV in a shared scene. Export your low-poly meshes or return the result through a bridge.
02 / UV LAB
A better fit.
Island by island.
See the model and UV layout together. Define seams, refine the unwrap and make the most of your texture space.
Start with the seams.
Mark seams by hand or use Auto Seams. Unwrap and Optimize while checking the result in the UV and 3D views.
Keep what works.
Guide edge directions and lock island position, rotation, scale or shape while refining the rest of the layout.
Use the space.
Arrange islands in the 0–1 tile, inspect UV errors and track occupied space. Keep overlapping islands together when needed.
03 / BAKE LAB
Keep the detail.
Lighten the mesh.
Project high-poly detail onto your low-poly asset. Organize the bake, control the cage and inspect the maps on the model.
Set up the projection.
Organize High and Low meshes into bake groups. Adjust the cage offset to control how the low-poly surface captures detail.
The maps you need.
Bake normal maps, ambient occlusion, thickness, curvature and position. Run all groups or bake only the selected ones.
Check it on the model.
Switch map previews in the 3D viewport, then export your baked textures. Bake keeps its own scene and settings.
BLENDER + MAYA BRIDGES
Your tools.
Working together.
Keep Blender or Maya at the heart of your workflow. Send selected meshes to Alpaca3D, work in the lab you need, and bring the result back.

Both bridges are also included with Alpaca3D. Each ZIP includes English installation instructions.
BlenderorMaya
Alpaca3D- Retopo
- Send reference meshes. Return new or edited low-poly geometry.
- UV
- Send meshes to unwrap and pack. Apply edited UVs back to the source objects.
- Bake
- Send High/Low meshes for baking. Export the texture maps from Alpaca3D.
Install the Blender add-on or Maya scripts from the included Bridge folders, then point the bridge to Alpaca3D. Setup instructions are included for each.

A FEW DETAILS
Before you begin.
Do I need Blender or Maya?
No. Alpaca3D has its own Retopo, UV and Bake workspaces. The bridges are optional ways to exchange meshes with Blender or Maya.
How do the three labs work together?
Retopo and UV share a scene, so you can work on the low-poly mesh and its UVs together. Bake uses an independent scene: load your bake meshes or send them through a bridge. Switching tabs does not automatically transfer a scene into Bake.
Where do I find the bridges?
The Windows package includes Blender Bridge and Maya Bridge folders with installation archives and instructions. Install the Blender add-on or Maya scripts manually, select the Alpaca3D executable, and send selected meshes from the bridge panel.
What can I save and export?
Save an .alpaca project to continue later, export low-poly meshes as binary FBX, and export baked texture maps. UV packing currently uses the 0–1 tile; UDIM packing is not supported.
