How we build a model: from reference to GLB

A ready-made model looks simple from the outside: one file, one click. Behind it is a pipeline we repeat for every asset in the catalogue. Consistency is the main promise of 3dpolyx, and consistency only comes from doing the same steps the same way every time.

Here is how a model travels from an idea to your project.

1. Choosing what to make

We start with a question: will people actually use this? We look at what game developers, motion designers and interior artists ask for, what is missing in our categories, and what fits the style of the existing catalogue. A model has to work on its own and next to its neighbours on the shelf.

2. Reference and style

Before any modelling, we collect references: photos, proportions, colour ideas. Then we adapt them to our house style: clean silhouettes, slightly softened shapes and a warm palette. The goal is a model that reads clearly from a distance and still looks good in a close-up.

3. Blockout

The first 3D version is a rough blockout made of simple shapes. At this stage we only check proportions and silhouette. It is much cheaper to fix a too-long scooter frame now than after the details are in.

4. Modelling

Once the blockout is approved, we build the final geometry. We keep the topology clean and avoid unnecessary detail in places nobody will see. Small details that would cost thousands of triangles often go into the textures instead.

Take our Vintage Motor Scooter: curved panels, chrome parts and a seat need enough geometry to stay smooth, but the bolts and stitching do not need to be modelled one by one.

5. UV unwrapping

Next we unwrap the model, laying its surface flat so textures can be painted on it. Good UVs mean even texture density, few visible seams and efficient use of texture space. This step is invisible in the final render, but you notice it immediately when it is done badly.

6. PBR texturing

We texture every model with a PBR (physically based rendering) workflow. Each material gets:

• Base colour — the pure colour of the surface, without baked lighting.

• Metallic — which parts are metal and which are not.

• Roughness — how shiny or matte each part is.

Because these maps describe the material rather than a fixed look, the model reacts naturally to the lighting in your scene, whether it is a sunny game level or a moody product render.

7. Optimisation and export

A model has to be practical, not just pretty. We check the triangle count, remove hidden faces, merge what can be merged and make sure the scale is in real-world units. Then we export a single GLB file with the textures embedded.

Every product page lists the final triangle and vertex counts. Our Snowman, for example, has 59,466 triangles and 33,052 vertices, which is light enough for real-time use and detailed enough for a close-up.

8. Quality check

Before a model is published, it goes through a checklist:

• Opens correctly in Blender and in a web viewer.

• Correct scale and orientation, with the pivot at a sensible point (usually the base).

• No missing or broken textures.

• Clean, readable object and material names.

• Thumbnail and 3D viewer show the real file, not an idealised render.

Only after that does the model appear in the store, with its price, specs and preview.

Why this matters to you

All of this happens so that you do not have to do it. When you drop a 3dpolyx model into your scene, it should sit on the ground at the right size, look correct under your lights and play well with the other assets you bought from us.

Browse the catalogue, open the Stone Windmill in the viewer, and see the result of the pipeline for yourself.
