Sloyd

What is Sloyd?

Sloyd is a parametric 3D asset generator that runs right in your browser. You either type a text prompt or pick a template from its library, and the tool builds a 3D model that is made of adjustable parameters rather than a fixed mesh. Move a slider and the model reshapes in real time, which is a very different workflow from traditional box modelling.

The company behind it is a small Finnish studio, and the tool was designed with game developers in mind. Generated models come with sensible topology, UVs and PBR materials, and you can export them to glTF, FBX, OBJ and USDZ so they drop straight into Unity, Unreal, Blender or a web project.

Key Features

• Text-to-3D generation from a single prompt
• A large library of parametric templates for common objects, props and environments
• Live parameter sliders that reshape geometry on the fly
• Built-in PBR materials with texture previews
• Export to glTF, FBX, OBJ and USDZ
• A developer API for generating assets programmatically
• Free tier that lets you test the generator without paying

How to get started

Getting going with Sloyd takes minutes. Create a free account, then either browse the template library or type a text prompt describing the object you want. The generator returns a model you can immediately start tweaking.

The real fun begins once you start dragging the parameter sliders. Each template exposes the dimensions and parts that were used to build it, so you can stretch a crate into a bridge or widen a sword blade without touching a single vertex. When you are happy, export in the format your project needs.

• Create a free account at sloyd.ai
• Pick a template or enter a text prompt
• Tweak the parameter sliders to get the shape you want
• Adjust materials and export to glTF, FBX, OBJ or USDZ
• Import into your game engine or 3D editor

Use cases

• Rapidly generating props, furniture and environment kits for games
• Creating placeholder or blockout assets for early prototypes
• Building web-based 3D experiences and configurators
• Producing base meshes that artists refine in Blender or ZBrush
• Making branded 3D content for social media and marketing

Pricing and licensing

Sloyd runs a freemium model. There is a free plan that is fine for personal projects and testing, while paid plans unlock commercial use, more generation credits, higher resolution exports and team features.

Exact prices change over time and depend on whether you pay monthly or yearly, so check the pricing page on the official website for current figures. The free tier makes it easy to judge whether the output quality suits your pipeline before you spend anything.

Pros and cons

Sloyd shines at speed. Generating a whole prop shelf in an afternoon, with everything editable afterwards, is something traditional modelling cannot match, and the browser-based editor means there is nothing to install. The parametric approach also means one template can cover an entire family of similar assets.

The trade-off is that output is template-driven, so results can feel generic compared with hand-built or fully generative models. Very complex or highly stylized assets still need a human artist, and the most useful features sit behind the paid plans.
