Ashley Graves 3d model from game The Coffin of Andy and Leyley (TCOAAL). 
This is a very interesting adventure about brother-sister relationships in a cruel world.

Modeled, painted, rigged, animetad in Blender. Blend file includes custom rig and IK constraints.

Give the model a spin. Notice how it is spinning around a central point and that central point is not at the center of the model? A pivot fix is in order! Just double-click on the background (or press spacebar on PC) to center the model (or its bounding box, to be exact). Now spin it around again and see how the model is easier to explore.

If you want to center and zoom into different parts of the model (e.g., the butterflies), double-click on them and the pivot will be adjusted again.

This technique can be used both when you are setting up your model in the 3D Editor and when you are viewing models with misplaced pivots.

For Pro members and above, you can set the pivot by activating camera constraints and moving the gizmo where you want the pivot to be. Then click on Save View.

A Minecraft Villager Made To be Animated. It has constraints in place to stop his body parts from going to far away from his original body (Not sure if this kept when I exported this). His UV's are layed out so you can put a regular villager texture onto him and everything will work properly.

The T200 Imperial Mech is equipped with two Gatling guns that can fire 80mm rounds. Up to 3 passengers can be seated in the T200 Mech. It has two searchlights that can be controlled from the inside to execute patrols.

> To say thank you to the Sketchfab team for their good work and to celebrate reaching 200 Twitter followers, I created this robot and share it with you as a freebie.
It's rigged, but the hydraulic stamps are based on constrains and they can't be exported from Cinema4D to FBX (I don't know if you can even write constraints in FBX format), so you'll have to reconfigure them yourself, but it shouldn't be hard.

A low poly, asian tower block. Intended for background use in scenes where optomisation is key. I tried to make it look as photorealistic as possible, with the given constraints of it being low poly. 

I used a lot of photobashing, using textures from www.textures.com

Red House
A red-brick apartment building built in the 1960s.

The 45-square-meter American-style apartment centers on cozy practicality, blending classic elements with modern design. An open layout breaks spatial constraints, while the integrated living-dining-kitchen area enhances a sense of spaciousness, complemented by natural tones like soft grays and creamy whites to create a comfortable ambiance. Solid wood furniture and linen/cotton textiles convey rustic charm, with accents like wrought iron pendant lights and vintage-inspired artwork adding nostalgic American flair. Glass partitions and hidden storage maximize vertical space efficiency, while simplified moldings and distressed finishes balance historical character with compact living needs. Ideal for singles or couples, it crafts a functional yet romantic mini-haven embodying the essence of Americana.

Here is my six-wheeled amphibious tank-design with some improvements for the rig.

I tried to create a simple rig animation control with ground detection for the wheels and the suspension.

Also I added some animation-constraints for the steering wheels in the front and the rear, the guns and the outboards.

The animation happens on bone-layer 1.

Just for fun I created a driving through a wall physics animation
by using cell fracture.

Another experiment at animation - which will turn into an entry for the [mechanical animal challenge](https://blog.sketchfab.com/sketchfab-3d-modeling-challenge-mechanical-animals) - inspired from a mechanical caterpillar sculpture in ["Les Machines de l'Ile"](https://www.lesmachines-nantes.fr/) in Nantes (France).

Geometry, textures and optimization were a little left behind for this model, as I spent most of my time fighting with Blender's parenting rules and animation constraints...

A version between WIP1 and WIP2. 

I plan to make a glass railing around the gear system to protect the citizens of this city.

I like this scene so I did not deleted. But  I thought it is way too early to make this glass railing.

**Gearsystem Control:**

Gear 64 is the gear which drive the gearsystem (I selected it).

Rotate this gear around the z-axis to move the other geras. 

Every gear has a transformation constraint which gets and converters the rotation from gear 64.

Mechanical City (WIP-1.5) Animation Constraints

The animated version of the [Earthquake map for the years 2010 and 2011](https://skfb.ly/6Mnsn) ([this model](https://skfb.ly/6MnyD) showing every earthquake since the year 2000 might also interest you ;) ).

The animation spans on the whole two years: a frame represents 6 days, and at 0.5x speed (the default value), one second is therefore equivalent to three months of data.

Although the main seismic zones are more easily visible on the static version of the visualization, the animation clearly helps to identify the earthquakes of February 2010 in Chile and March 2011 in Japan, which appear as bright "flashes".

Their respective aftershocks - spanning on a few weeks/months - are also visible and clearly showcase the relaxing of mechanical constraints in the subduction zones.

Colored by magnitude (blue=low to red=high).

[Excerpt from Halopedia: https://www.halopedia.org/M808_Scorpion]

Information regarding functional & visual distinctions between Halo's scorpion variants (M808, M808B, & M808C) is superfluously scattered. I've decided to make this distinct from the others we see in the mainline games, and label this one simply as "M808"; (an earlier variant of scorpion).
This particular design can be tracked to the **Halo Wars - First Announcement Trailer (2006)**, at the 0:22 second mark.

> "The Bkowe'nei-pattern support fighter (UNSC Type classification: Type-29 Close-Support Fighter), more commonly known as the Vampire, is an atmospheric anti-aircraft fighter formerly in service with the Covenantmilitary. Manufactured by Assembly Forges, the Vampire was used during the early years of the Human-Covenant War. However, its role was eventually overtaken by better-armed and more versatile vehicles, leading to the Vampire seldom seeing deployment in the war."

This model is a mechanical spinner assembly designed using Autodesk Inventor.

The assembly demonstrates rotational motion using a central deep groove ball bearing. The inner ring is fixed while the outer ring is constrained to the spinner body, allowing realistic rotational degrees of freedom.

This project was created to practice assembly constraints, grounding, and motion simulation in Inventor.

Software Used: Autodesk Inventor
File Format: glTF (.glb)

Designed as part of mechanical CAD learning and motion analysis practice.

Before the release of Chapter 5, I created this model based on the trailer. However, due to time constraints, I was unable to finish painting the textures.
And In order to ensure optimal performance, the use of polygons has been minimized. This is the reason why some areas may not be as smooth as expected.
