In Blender 5.2 or newer, open Preferences > Add-ons > Install from Disk, select AutoCreatures_Addon_1.0.zip and enable AutoCreatures. Open the matching AutoCreatures_1.0.blend, save your own working copy, then open View3D > Sidebar > Creature Studio (AutoCreatures panel). Restart Blender after replacing an earlier installation.

The catalog contains 50 body bases (30 torsos and 20 quadruped bodies) and 399 other modular parts: 449 physical templates.

A 27-page English User Guide and editable workflow examples are included.

Yes. Add extra copies with Drag to surface > Add a copy, then select each instance in Installed to adjust its size, local seam fitting and pose.

No. It reports PASS, WARN or ERROR for the selected scope, with issue counts and selection tools to help you inspect problems. Make your changes and run a fresh check. Open boundaries can be intentional in an editable modular assembly; a local connection check and complete surface closure are separate results.

Sculpt creates a separate voxel surface for further sculpting. Game creates a separate deform copy with one skeleton and a result report, with welding for supported requested connections. Both preserve the editable source assembly. Inspect fit, thin details, connections and bent-pose deformation, and test exported FBX in your destination project. Further cleanup, retopology or materials may be needed for your design.
