Blazing fast Multi-GPU and CPU rendering, at a fantastic price. All of the rendering speed and accuracy of Indigo Renderer, for artists who don't need the functionality aimed at specialist applications, but demand the highest rendering quality available on the market.

What's new in Indigo RT 4?

Multi-GPU rendering

Indigo RT uses our new OpenCL-based GPU engine that provides industry leading performance on Nvidia and AMD graphics cards on all major operating systems. With a modern GPU, it's approximately 10x faster than the high performance CPU core of Indigo RT 3.8.

And it doesn't stop there. Simply add more cards to your computer and get the horsepower to quickly render incredible 4K images and animations.

Fast, flexible region rendering

Region rendering is now a snappy and interactive experience. After enabling it, simply drag over desired area and it'll start rendering. The user can render multiple regions at once by shift + dragging, and enable a transparent background with a single checkbox.

Aperture controls

Render the perfect bokeh by controlling the aperture shape with Indigo's generated aperture, or add your own aperture maps. Cover the lens with custom obstacle maps to create beautiful flare effects.

RGB colour curves

RGB colour response curves are a great way to tweak the raw image to get photographic effects. Doing this with Indigo's native RGB curves means it's done in extremely high precision, and doesn't need to be repeatedly added in post-process for several renders.

Material preview window

Indigo 4 features a highly customisable material preview window for tweaking the scene materials in a neutral lighting environment. There are multiple sample objects available, and the user can change resolution and render quality of the preview.

Sequence overrides

An useful new tool for rendering batches of images and animations, the render queue overrides allows you to change render settings for all the frames in the queue, on the fly.
