Altair® Inspire™ Render

3D Rendering and Animation Powerhouse

Inspire Render is the new 3D rendering and animation powerhouse for innovative designers, architects, and digital artists to produce stunning product presentations faster than ever before.

Quickly create, modify, and drag-and-drop a variety of materials and add lighting environments to generate images and animations in real-time with the built-in high-quality, physically-based global illumination rendering engine Thea Render. Find it all in a slick and efficient user experience that fulfills the needs of novice and expert users alike.

Supporting CUDA and OpenCL, Inspire Render leverages the latest high-end graphic processor technology. No dedicated GPU card? No problem, fast production rendering by the software’s interactive Presto/IR engine enables immediate feedback on production quality, while being versatile, quick, and fun to use.

Running on both Mac OS X and Windows as a standalone product or under Altair’s flexible token-based licensing model, Inspire Render frees designers’ creativity from the constraints of traditional tools, while assuring export of robust digital models for product development.

Why Inspire Render?

Unlimited Versatility

Run interactive photo-realistic rendering on GPU/CPU with the Presto/IR engine for stunning images with the Full progressive core, or use the raytracing engine for faster, higher-quality rendering and walkthrough animations.

Recalibrate Reality

Use the intuitive material system setup, with physically based material primitives and advanced layering system, to create the most realistic and convincing renders with accurate lighting.

Natural Experience

Created by designers for designers, Inspire Render's workspace is the most natural and immersive environment to bring ideas to life, without fiddling with panels and parameters.

Key Features

Light Simulation

Using a strong mathematical framework, the light simulation core performs calculations in the full visible spectral space to inspect complex phenomena like volumetric scattering and spectral dispersion.

Interactive Rendering

Get immediate feedback on your scene while navigating throughout and applying materials and lighting. It’s fun to setup and accelerates productivity.


Efficient geometric compression techniques allow you to render millions of instanced polygons without issue. If a scene exceeds a GPU, then run entirely on the CPU.


Leverage NVIDIA OptiX to deliver fast, unsurpassed denoised renders. If a NVIDIA graphics card is not available, the built-in denoiser can still accelerate production rendering.

Material Library

Drag-and-drop materials from the built-in comprehensive library or custom build from a basic, metal, glass/gem, coating, metallic flake, emitter, or shadow catcher material.

Open Framework

With I/O interfaces to the most common CAD and CAID tools included at no extra cost, Inspire Render integrates seamlessly into existing workflows.
