Blender is a powerful, flexible 3D creation tool — and it’s completely free. It covers the entire 3D pipeline: modeling, animation, VFX, simulation, and rendering. With Cycles and Eevee as its built-in rendering engines, Blender supports both realism and real-time performance.
By combining Blender with UltraRender’s GPU servers, you can render faster, handle larger scenes, and avoid hardware limitations. This setup is ideal for artists, freelancers, and studios looking to work efficiently without buying expensive equipment.
In this article, we’ll explore how Blender rendering works, what makes it unique, and how GPU servers help you get more done with less waiting.
What is Blender?
Blender is an open-source 3D creation suite used in animation, film, product design, architecture, and more. It supports every stage of 3D production. The software includes two key rendering engines: Cycles, which is ray-traced and focused on realism, and Eevee, which is real-time and optimized for speed.
Both engines benefit from GPU acceleration, especially Cycles. While Eevee delivers quick previews and stylized results, Cycles is designed for final output with physically-based lighting and material accuracy. As scenes grow more complex, GPU performance becomes critical.
Blender also supports scripting, plug-ins, custom nodes, and external render engines. Its flexibility has made it a standard in both independent and commercial pipelines. With GPU servers, its capabilities scale even further.
Key Features of Blender Rendering
1. Dual Rendering Engines: Cycles and Eevee
Cycles is a ray-tracing engine that focuses on photorealism. It simulates light and material interactions accurately. Eevee is a faster real-time engine that works well for stylized or interactive projects. You can switch between both depending on your workflow.
2. GPU Acceleration for Cycles
Cycles takes full advantage of NVIDIA GPUs using CUDA or OptiX. This greatly improves render times. On multi-GPU setups like those offered by UltraRender, Cycles can distribute workloads across several cards — reducing the time needed to complete complex scenes.
3. Denoising and Adaptive Sampling
To make rendering more efficient, Cycles supports adaptive sampling. It concentrates samples where they’re needed most. Built-in denoising, including AI-based tools like NVIDIA OptiX, cleans up images without requiring high sample counts. This shortens render time while keeping quality high.
4. Advanced Material and Lighting Tools
Blender features a node-based shader editor that supports PBR materials, subsurface scattering, volumes, and displacement. Lighting options include HDRIs, area lights, and light probes. These work seamlessly with both Cycles and Eevee, depending on the project’s demands.
5. Compositing and Render Layers
Blender includes a built-in compositor. You can split scenes into passes and layers for post-production, all without leaving the software. This is useful for VFX, motion graphics, or adjusting scenes after rendering.
6. Batch Rendering and Headless Operation
Blender supports command-line rendering and headless operation. This allows automated rendering on remote servers. For teams or solo artists managing large projects, this is a great way to queue renders and free up time.
How Blender Works with GPU Servers
Blender’s rendering engines are designed to benefit from modern GPUs. When you combine that with UltraRender’s hardware, the workflow becomes faster, smoother, and more scalable.
1. Multi-GPU Rendering for Speed
On supported systems, Cycles can use multiple GPUs at once. UltraRender servers offer 2, 4, or 8 GPUs per machine. This allows complex projects to render in a fraction of the time. As a result, you can meet deadlines without sacrificing quality.
2. Remote GPU Workstations
Need full control over your scene? With UltraRender, you can log in to a high-performance remote workstation. You’ll have access to a full Blender setup with 4K display support and fast NVMe storage. It feels just like using your own PC — but with much more power.
3. Network and Batch Rendering Support
For animations or large renders, Blender supports batch jobs and network rendering tools like Flamenco. You can queue frame sequences, automate processes, and distribute jobs across multiple GPU servers.
4. Scalable, On-Demand Power
There’s no need to maintain a personal render farm. With UltraRender, you rent what you need, when you need it. This makes it easy to scale up for a project, then scale down once it’s complete.
Why Blender Rendering Thrives on GPU Servers
1. Faster Renders and More Iterations
Using GPU servers, you can reduce render times significantly. This allows more test versions, higher resolutions, and more lighting or material variations — without slowing down your project.
2. Handles Large, Complex Scenes
As your projects grow, local machines may struggle with memory or processing limits. UltraRender servers offer 64–512 GB of RAM and GPUs with up to 32 GB VRAM. This ensures that even detailed environments and high-resolution textures render smoothly.
3. Lower Costs with Greater Flexibility
Instead of buying and maintaining hardware, you rent what you need. Pricing is predictable and scalable. There are no hidden data transfer fees, and you can choose between short-term or monthly access.
4. Seamless Integration with Your Workflow
You can use Blender just as you normally would. Open your file, set up your scene, and render. Whether you’re working locally, through a remote workstation, or headlessly on the server, the workflow remains consistent.
Blender + UltraRender = Speed and Scale Without Limits
Blender is a powerful tool on its own. But with GPU servers from UltraRender, you unlock its full potential. Whether you’re using Cycles for realism or Eevee for speed, rendering becomes faster, smoother, and more flexible.
With access to powerful remote machines, you don’t need to worry about hardware bottlenecks or long wait times. Whether you’re rendering short films, architecture, product animations, or visual effects, UltraRender provides the infrastructure you need — when you need it.
