blRstr: A ReSTIR/RTXDI-based Blender Render Engine.

Direct and indirect lighting from tens of thousands of lights with real-time frame rates directly inside the viewport.

blRstr will become open source soon! For now you can download the binary from github or buy it here for $0. More info soon here.

Buy now at a special early bird price.

Note: This is a license for a software still in development ("beta")!

If unsure, you may want to use the free (time-limited) beta releases, and buy later for the full price.

Features

  • RTXDI-based lighting:
  • - Direct lighting of primary surfaces with RTXDI's spatio-temporal resampling.
  • - Up to 15 indirect bounces from secondary surfaces accelerated with RTXDI.
  • NRD-based denoising (ReLAX)
  • Supports almost all* surface shader nodes available in Cycles GPU for Material, Light and World.
  • *Displacement, Volume, Hair and Subsurface are currently not supported. OSL is not supported. Some nodes are partially supported. See detailed list below.
  • Emission shaders have some real-time limitations. See this FAQ entry.
  • Stochastic approximation for Mix/Add Shaders and alpha. Please find a more detailed explanation here.
  • Special optimizations for common Mix/Add Shader cases ([Any]+Emission, Diffuse+Glossy).
  • Does not support motion blur.
  • Works with Blender 3.1+ and LTS 2.93+. No other add-ons required. Experimental Blender features are not supported.
  • Requires Windows 10 with DXR 1.1. DXR-capable GPU required. RTX 2070 or higher recommended.
  • The core of the product is commercial. The Blender add-on is open source. Please find a more detailed explanation here.
  • While the product is currently based on Direct3D, it may switch to Vulkan later. The functionality and system requirements would remain unchanged.
