Spider - Rigged & Animated Creature

A realistic arachnid, rigged and animated, with a control panel inside Blender.

What's in the package

• Spider.blend - demo scene: rigged spider, 5 animations, textures and normal map (packed), plus the Spider panel encapsulated inside the file
• Spider.fbx - for Unreal, Unity, Cinema 4D, Maya
• Spider.glb - for the web, Godot and glTF pipelines
• Texture maps: Base Color 4096 + Normal 2048
• README.txt and License.txt

Quick start

1. Open Spider.blend.
2. Press N in the 3D viewport and open the Spider tab. The panel is already inside the file and appears on its own.

If you don't see the Spider tab:

• Preferences → Save & Load → tick Auto Run Python Scripts, then reopen the file; or
• open the Text editor, select Spider_Animation.py and press Run Script; or
• install the add-on (see below).

The panel (N > Spider)

• Play / pause - starts and stops playback (the spacebar works too)
• Idle - rest: feet pinned to the floor, body rising and falling
• Walk - walking in place
• WalkFwd - walking forward in a straight line (root motion)
• Run - running
• Threat - threat pose, front legs raised
• Seconds - duration of the straight walk; press to regenerate WalkFwd
• Speed (FPS) - playback speed
• In front - draws the skeleton over the mesh
• Bones - bone display style
• Bump - normal map intensity (0 = off)

Animations without the panel

The clips live inside the .blend: open the Action Editor or the NLA Editor and pick Idle / Walk / WalkFwd / Run / Threat.

1. Do not unzip the add-on archive.
2. Blender → Edit → Preferences → Add-ons
3. Arrow at the top right → Install from Disk...
