Indigo Renderer 4.2.23 Stable RC | 232.1 mb
Glare Technologies has released a Stable Release Candidate of Indigo Renderer 4.3.23, the long-awaited update to its unbiased renderer, adding fixed two customer-reported issues.

version 4.2.23 - Changelog:
- GPU: Fixed issue with multiple double-sided thin materials in scene.
- GPU: Fixed issue with realtime changes when an IES light is enabled.

About Indigo Renderer 4.2. Indigo Renderer is an unbiased, physically based and photo-realistic renderer which simulates the physics of light to achieve near-perfect image realism. With an advanced physical camera model, a super-realistic materials system and the ability to simulate complex lighting situations through Metropolis Light Transport, Indigo Renderer is capable of producing the highest levels of realism demanded by architectural and product visualization.

The Indigo 4.0 release was the first version to have full GPU path-tracing support, as well as lots of other cool stuff. With the 4.2 release we have taken the opportunity to push the performance on GPU even further, as well as making some algorithmic improvements to the CPU rendering.

GPU rendering optimisations

There are a couple of big GPU (OpenCL) rendering optimisations in this release:
* We have added high quality BVH building in the background and transparent swapping out from an initial fast BVH build.
This allows the best of both worlds - the scene starts rendering (builds) as fast as possible, but keeps optimising in the background, and then switches to an acceleration structure that gives the fastest possible rendering in samples/second.
* We have added an optimisation for faster rendering if the scene can be made to render without instancing -
while we support instancing on the GPU (instancing is the duplication of objects in a scene without much increase in memory usage), if the scene can be rendered without instancing we can get big speedups.

These two optimisations combined allow some scenes, such as interior scenes, to render around 70% faster or even more in some scenes!

CPU rendering improvements

We have made some optimisations on the CPU rendering side, but the biggest improvements are to do with smarter sampling of emitters.
