Why Blender is at the heart of our creative studio

Blender, much more than a 3D software

In a web design studio, tool choices are never trivial. At Junca, we made a clear decision: Blender is at the center of our creative pipeline.

This isn't a default choice. It's a strategic one. Blender lets us combine 3D modeling, motion design, photorealistic rendering, and web integration in a single environment. No license. No constraints. No compromise on quality.

Here's how we use it every day, and why we think it's the most underrated tool in modern web design.

A modeling tool that adapts to all our projects

Every client project has its own visual requirements. A website for a cosmetics brand has nothing in common with a landing page for a SaaS startup. What doesn't change is our need to create custom 3D assets, quickly, with a controlled level of detail.

Blender covers the full spectrum. Polygonal modeling for technical objects. Sculpt mode for organic shapes. NURBS curves and surfaces when we need industrial precision. We switch between modes without changing software, without exporting, without wasting time.

3D assets designed for the web from the start

The difference between a 3D asset created for offline rendering and one designed for the web is massive. On the web, every polygon counts. Every texture must be optimized. File weight directly impacts load time and Core Web Vitals.

We model with this constraint from the start. Low-poly when possible. Baking normal maps to simulate detail without adding geometry weight. Exporting in glTF/GLB, the standard format for web 3D, directly from Blender. This workflow lets us deliver interactive 3D scenes that load in under 2 seconds on mobile.

Geometry Nodes: our secret weapon for generative design

If we had to name one feature that transformed our design approach, it would be Geometry Nodes. This procedural modeling system, introduced in Blender 2.92 and massively expanded since, allows creating complex shapes from rules and parameters.

In practice, we no longer model an object point by point. We define a system. We adjust sliders. We get infinite variations from a single visual logic.

Real-world use cases

We use Geometry Nodes to generate organic patterns that dress website backgrounds. To create product grids with automatic placement and controlled random variations. For complex particle animations that we then render as image sequences or video for the web.

The advantage is twofold. First, speed: what would take hours in manual modeling is done in minutes with a well-built node tree. Second, flexibility: when the client asks for a variation, we adjust a parameter instead of starting over.

From 3D rendering to the browser: our web integration pipeline

Creating a beautiful 3D asset isn't enough. It needs to reach the browser in a smooth, performant, and interactive way. That's where our web development expertise comes in.

Three.js and WebGL: real-time 3D in the browser

For interactive 3D experiences, we use Three.js, the reference JavaScript library for WebGL rendering. We export our Blender scenes in glTF, load them in Three.js, and add interactions: scroll-driven rotation, cursor reactions, animated transitions.

The result: a product you can manipulate in 3D. An immersive environment. Custom shaders impossible to achieve with CSS alone.

Scroll animations and visual storytelling

One of our signatures is scroll-driven animation. The user scrolls, and the 3D scene evolves in parallel. An object deconstructs. A camera moves through 3D space. Text and visuals synchronize to tell a story.

We prepare these animations in Blender: keyframes, camera trajectories, pre-calculated transitions. Then, we connect the timeline to scroll position via JavaScript. The result is smooth, controlled, and reversible in both directions.

Pre-rendered output: when real-time isn't necessary

For a hero section with a static 3D visual or looping animated backgrounds, we use the built-in render engines. Cycles produces photorealistic renders with physically accurate path tracing. EEVEE offers fast rendering for previews and lightweight animations. Export in WebP, AVIF, or compressed video as needed.

Blender and Spline: two complementary approaches

We're often asked: why not use Spline directly? Spline is excellent for web-native 3D, with native React and Framer integration.

But Spline has its limits. Scene complexity is lower than what Blender allows. Control over shaders and materials is less refined. And you depend on a third-party service with its own pricing.

We use Spline for certain quick prototypes and simple 3D elements in Framer. For anything requiring precision or high-end rendering, Blender remains our primary tool. Both coexist in our pipeline.

Open-source as a studio philosophy

Blender is free software, distributed under the GPL license. No monthly subscription. No per-seat license. No hidden costs that explode as the team grows. It's an obvious financial advantage, but it's not the most important one.

Open-source also means community. The add-ons created by the Blender community are remarkably high quality. Tools like BlenderKit for assets, the countless YouTube tutorials, the specialized forums: this entire ecosystem accelerates our learning and production.

Constant updates, rapid innovation

The Blender Foundation ships major updates every quarter. Geometry Nodes, the new EEVEE Next render engine, sculpt improvements, USD support: each version brings features that rival software sold for thousands of dollars per year.

For a studio like ours, it's a direct competitive advantage. We access the same tools as major animation studios, without the associated budget. And we can reinvest those savings into what truly matters: the time spent on art direction for each project.

Motion design and animation: bringing interfaces to life

The static web is dead. Users expect movement, transitions, life in their interfaces. Blender lets us create motion design sequences directly integrated into our web projects: 3D animated logos, section transitions, looping micro-animations that add rhythm without overwhelming.

From storyboard to web component

We storyboard the animation with the client. We create it in Blender frame by frame. Then we export in the appropriate format: sprite sheet for lightweight animations, WebM video for long sequences, or Three.js scene for interactive animations.

Every animation has a purpose. It guides the eye. It supports the narrative. Never gratuitous motion.

Flexible delivery: adapting to the client's tech stack

Every client has their own technical ecosystem. WordPress, Webflow, custom React frameworks. Our use of Blender makes us agnostic: static renders (WebP, AVIF) for any CMS, glTF files for React Three Fiber, optimized videos, image sequences for scroll-driven animations.

Clients aren't locked into a proprietary format. They receive standard, reusable, and documented assets.

FAQ: Blender in a web design studio

Is Blender really free for commercial use?

Yes, completely. Blender is distributed under the GNU GPL license. You can use it for commercial projects without any restriction or royalty. The files you create belong entirely to you. It's one of the few professional software tools of this caliber that is 100% free and open-source.

Does 3D on the web slow down the site?

Not if it's done right. A 3D scene's weight depends on asset optimization: polygon count, texture resolution, export format. A well-optimized glTF model can weigh less than 500 KB. We systematically work with strict performance budgets to keep Core Web Vitals in the green. In some cases, a static WebP render will be more appropriate than a real-time scene.

Why not use Cinema 4D or Maya instead?

Cinema 4D and Maya are excellent software, but their licensing model (annual subscription between $700 and $2,000 per seat) isn't justified for our use case. Blender covers 100% of our modeling, animation, and rendering needs. The open-source community and the Blender Foundation's development pace give us confidence in the tool's longevity.

Can you integrate Blender 3D into a Framer or Webflow site?

Yes. For Framer, we can integrate static renders directly, or use React components with React Three Fiber for interactive scenes. For Framer, we use HTML/JS embeds with Three.js or optimized videos and images. In both cases, assets are created and exported from Blender.

How long does it take to learn Blender?

Blender's learning curve was long known as steep. Since version 2.8 and the complete interface redesign, it's much more accessible. For a designer who wants to create simple web 3D assets, expect a few weeks of regular practice. To master Geometry Nodes or advanced rendering, it's an investment of several months. The wealth of free online resources makes this learning very hands-on.
