How our 3D models are made

What “correction in Blender” means

Fragments and splinters

Generated meshes often carry loose duplicate shells that sit almost on top of the main surface, plus tiny detached splinters. They cause dark patches and flickering, so they are removed (with size limits, because a filter that is too greedy once ate real parts of a model).

Surface noise

Generated surfaces are finely noisy. When the mesh is reduced, that noise turns into visible wedges, so the reduced mesh is smoothed again afterwards.

Holes, but not all of them

Only small gaps are closed. Openings that belong to the object, like the spaces between bicycle spokes, stay open.

Scale and stance

The longest dimension is set to a plausible real size, the pivot moves to the base center, and the model is levelled only when the correction is small. A slightly tilted whale is better than one rotated by an algorithm guessing its “ground”.

Textures

Maps are checked, logos or lettering are removed where they appear, and the textures are re-encoded so a 4K download does not carry a bloated file.

How the kits are built

Each kit has its own small toolbox of Python functions for its typical shapes, a fixed palette and a brief that describes every piece. Pieces are generated headless in Blender, then weathered: dirt, rust and edge wear are baked into the PBR textures, while glass and glowing parts stay clean.

Two sample pieces are built and approved first so the style is fixed before the rest of the kit follows. After each round the pieces are rendered and compared side by side, so a kit reads as one set rather than a pile of individual models.

Rigs and low poly variants

Rigged characters

Biped characters can be rigged automatically. They get a humanoid skeleton and two in-place clips, walk and run. The rigging step replaces the texture with a weaker one, so we bake the original texture back onto the rigged mesh and check the result in motion. Four-legged animals cannot be rigged this way, so they are offered unrigged.

Low poly versions

Some High Detail models get a separate low poly model: the detailed mesh is remeshed, reduced step by step, and its colors are transferred into a small palette texture. That is how the wolf became the low poly wolf, with its own page.

Why we can release the models under CC0

We create every draft ourselves, from reference images made for this purpose, using generation services whose terms allow us to use the results commercially and to pass them on. The corrections, rigs, variants and all kit scripts are our own work, the scripts written with the help of an AI coding assistant.

Where rights exist in the result, they are ours to give up, and CC0 1.0 does exactly that: we waive them worldwide, as far as the law allows. In many countries purely machine-generated content may not be protected by copyright at all. With CC0 you get the same clear answer either way.

Subjects are generic: no brands, logos or real people. If you ever find something that looks like it shouldn’t be there, tell us and we will check it.

What we don’t claim

• Our models are not handmade, and we never label them that way.
• AI drafts can hide errors we miss despite the checks. If you find one, write to us and we fix or remove the model.
• High Detail models are heavy by design (hundreds of thousands of triangles). For crowded game scenes, use the lighter file, a low poly version or your own LODs.
• Automatic rigs have limits: a humanoid skeleton without finger or face bones, and only walk and run clips.
