Jul 23, 2018
  • Added support for DWAB OpenEXR compression method. (highly compressing)
  • For trackball-style camera controller, prevent zooming in too far to an object. This helps prevent the camera passing through objects.
  • Fixed problem with object merging resulting in objectId() being the same for multiple objects.
  • Added objectId() GPU support.
  • Made posOS() work in bump shaders on the GPU.
  • Fixed posOS() on CPU, was slightly wrong in bump shaders.
  • Fixed problem where posOS() was incorrect due to object merging.
  • Improved robustness and speed of motion blur.
  • Fixed bump values being different based on object merging.
  • Added normalOS() ISL function.
  • Using bump-mapped shading normal in shaders where possible, otherwise using pre-bump shading normal.

New in Indigo Renderer 3.6.26 (Nov 14, 2013)

  • New material types:
  • Indigo 3.6 introduces several new material types and options for greater flexibility in material creation.
  • The Coating material simulates a thin, smooth coating on top of a base material, which can be useful for adding shininess to surfaces, from wooden floors and car paints to wet concrete.
  • The Double-sided Thin material is especially useful for realistically modelling leaves, which reflect light differently on the top and bottom sides, and have a degree of scattering through them. Creating stunningly realistic foliage using this material is straightforward, and it is well documented in the online manual.
  • The behaviour of the Phong glossy coating has also been improved to better match the physical appearance and energy conservation of coated materials; the result is more realistic renders, without having to touch any settings.
  • Hiding objects from view:
  • Objects can now be made invisible to direct viewing from the camera. They still cast shadows and interact normally with any other light, except they can't be seen directly by the camera.
  • It can be used to make invisible light sources or to peek through walls without creating unrealistic lighting situations.
  • Spherical camera:
  • Another very useful new capability in Indigo 3.6 is rendering with spherical cameras to produce high quality panorama images in standard latitude-longitude format.
  • This can be used either to create new HDR environment maps from your scenes, or with an interactive panorama viewer to allow realtime 360 degree viewing.
  • Improved 3ds Max integration:
  • Indigo's integration with 3ds Max (via IndigoMax) has been tremendously improved since Indigo 3.4, with many bug fixes, workflow improvements and Indigo features supported.
  • ndigoMax directly integrates Indigo's rendering into 3ds Max and works entirely in memory, so you don't have to wait for your hard drive during a scene export or material preview, greatly accelerating the modelling process.
  • Scene changes are immediately reflected in the render output with the Interactive rendering mode, which is a great productivity enhancer if you are making many small changes quickly.
  • Improved Revit integration:
  • Thanks to tremendous improvements in Revit 2014's addin system, Indigo can now access detailed material descriptions for much more accurate material conversion, without any user effort!
  • Grass scattering is a particularly nice new feature in this release, that makes spreading realistic 3D grass in your scenes a snap: simply select the grass materials in your scene, and it happens automatically on export.
  • Support for IES lights in Revit has also been greatly improved, allowing you to use many realistically modelled light sources in your scenes.
  • Intensive ongoing development:
  • Besides the many improvements and fixes in this 3.6 release, we have been working on other exciting new features which will be available in upcoming beta releases!
  • Object scattering is a very useful feature for distributing many object instances over a surface, which dramatically speeds up creating many instances, for example trees in a forest.
  • A new architectural glass material massively improves convergence speed in typical interior settings.
  • The Metropolis Light Transport implementation has been greatly improved too, producing much cleaner renders for the same rendering time. Further work on this will make the performance gain even more pronounced.
  • Subsurface scattering (SSS) has been optimised, resulting in 2x faster rendering in scenes with heavy scattering.
