1.3.5 - 2019-2-15

Materials

  • Displacements can now be rendered directly from the surface material and are easily interchangeable with Bump mapping. This improves usability as it allows artist to develop the look of an asset in the most logical place: the surface shader. Creation of separate displacement nodes is not necessary both in Maya and Katana.

3Delight for Maya

  • Thanks the newly available displacement capabilities, the Material Viewer can now show displacements created by 3Delight shaders.

1.3.0 to 1.3.4 - 2019-2-12

This version contains two critical performance fixes:

  • An important memory optimization for OpenVDB volume rendering. Memory savings are substantial (up to x8).
  • A performance optimization for extremely large scenes (millions of primitives or instances). This problem affected startup time in such scenes.


3Delight for Maya

  • Allow for custom export delegate for dependency nodes. 

3Delight for Katana

  • Fixed live render crash.

1.2.19 - 2019-2-08

3Delight Cloud

  • Better behaviour of the "sync wheel" in 3Delight Display for very short renders.

1.2.17 + 1.2.18 - 2019-2-07

The Nodal Scene Interface (NSI)

  • Introducing a procedural API to NSI. An interesting design feature of this API is that NSI procedurals do not have to pre-link with any rendering  library, making NSI procedurals truly rendering agnostic.

3Delight for Katana

  • Support live render operations on the Render Working Set.

3Delight for Maya

  • Support array of numeric attributes (including strings) on shading nodes.


1.2.16 - 2019-2-01

1.2.15 - 2019-1-31
  • Optimized OSL optimization step for very large groups of shaders.

3Delight Cloud

  • 3Delight Display window opens much earlier for cloud renders. This allow the "sync wheel" to show up earlier and provide more information to the user.

  • Always use local material for live render updates.

3Delight for Maya

  • Fixed handling of invisible objects feeding instancers.

1.2.14 - 2019-1-26

1.2.13 - 2019-1-22

  • Fixed bad values in CryptoMatte output when using floats.

3Delight Display

  • Renders were sometimes sent to the wrong image. Fixed.

1.2.12 - 2019-1-17

This release fixes a major performance issue with instancing. Scenes with millions of instances suffered from very long startup time.

1.2.11 - 2019-1-9

  • Fixed a bug with image intensity when using very low shading samples.

3Delight for Katana

  • Default filter is now Blackman-Harris as is to provides a nice balance between definition and softness in a variety of situations.
  • Updating UI for Matte and Pre-lit attributes.
  • Fixed dlSet AE template

3Delight for Maya

  • Export arbitrary attribute with  pointcloud geometry.

Materials

  • Fix an orientation probled in place3dTexture.

  • Added support for pointcloud geometry type.

3Delight Display

  • Fix display problems when the device pixel ratio is not an integer (more usual for high resolution such as 4K displays).

1.2.6 - 2018-12-09

3Delight for Maya

  • Allow a dlSet to be used as a group for Multi-Light output.
  • It is now possible to render many frames at the same time using 3Delight Cloud. This is possible by setting a frame range in the render settings and selecting 3Delight Cloud as a renderer. 

3Delight for Katana

  • Export all arbitrary attribute along with geometry. Shaders can now access these attributes using the dlPrimitiveAttribute shading node.

3Delight Display

  • Fixed magnifier tool when looking outside of the image region.

Materials & Shaders

  • Fixed a crash bug with displacement on Windows.
  • Fixed stack trace output on Windows. The stack trace now contain more meaningful information, helping us pinpoint potential problems more rapidly.

3Delight Display

  • Live renders from Maya now respect the crop window as a priority window.  In other words, this is the "follow mouse" feature for live renders.
1.1.21 - 2018-11-19

Importance Performance Fix

This version is recommended to all 3Delight users who use the Windows operating system as it fixes a potentially serious performance problem which could make renders several times slower than they should. The main symptom is a ver low CPU usage when rendering larger scenes.

  • Reduced OpenVDB memory usage when the same OpenVDB is re-used.

3Delight for Maya

  • Batch renders are now using the horizontal bucket order instead of the spiral. This means that files save on disk will contain complete row of pixels early during the render process.
  • Added ability to write custom OSL shaders that have message based parameter. For example, connecting a Maya camera to a string parameter now works (the shader will receive the name of the Camera's transform).

OSL Shaders

  • The Glass shader is now significantly more powerful as it allows rendering of absorption and scattering of light inside the medium. This shader can now be used to render, e.g,  realistic volumes of water.
1.1.18 - 2018-11-13
  • macOS packages are now properly signed. Installation won't mention an "unknown publisher" anymore.
  • Floating point textures compress x2 better when optimized.
  • 20% faster displacement in scenes with a lot of displacement. This also improves time to first pixel.
  • Fixed normal interpolation along curves (it was not smooth).
  • Fixed crashes and hangs at the end of renders affecting Windows packages.
  • The path tracing algorithm can now deal with Prelit materials as described in:
    Prelit materials: light transport for live-action elements in production rendering

3Delight for Katana

  • Fixed slowdown issues happening on Katana 3.1.
  • Fixed rare exception on DlSettings creation on Windows machines.
  • Added a Prelit attribute in the Visibility section as well as a RelightingMultiplier output variable.

3Delight Display

  • Fixed a performance issue on macOS when using sRGB color space.
  • The mouse scrolls wheel can now be used to zoom in/out the image.
  • A multi-touch trackpad can now be used with two fingers to pan the image and zoom in/out (pinch to zoom).
  • Fixed Re-Render when renders are started from Katana.

3Delight for Maya

  • Added Prelit workflow. This means "Prelit" attributes on objects and sets as well as a new AOV : "Relighting Multiplier".

OSL Shaders

  • Fixed IOR controls in Glass shader.
  • Fixed a crash when using getattribute( "global:..." ) inside OSL shaders.
1.1.10 - 2018-10-28

  • Fixed rendering of VDB volumes on 3Delight Cloud when renders are started from a Windows platform.

  • The workspace UI has been removed as it is now empty.
  • 3Delight Glass now show transparency in the VP2 viewport. 
  • Added a Volume AOV.
  • Fixed 3Delight Display on Retina displays when started from Maya. The issue was causing the doubling of pixels.
  • Fixed Abort button behaviour for Cloud renders. It was non-responsive and sometimes resulted in the application to crash.
  • Fixed Material Viewer. Viewing and editing of both shaders and environments are supported. 
  • All 3DelightNSI error messages are now shown in the Script Editor instead of the terminal. This is particularly important on macOS and Windows where the terminal is not always available, making error messages not shown at all.
  • Improvements to the templates generated for auto-loaded OSL shaders.
  • An NSI file export now has the same scene output as a batch render. This means frame buffer and overrides options are not exported in the NSI file.

  • Added Flake 3D texture shader.
  • Added a Facing Ratio utility shader.
  • Added a Worley Noise and a Flake 3D Textures.
  • OSL shaders can now declare a classification string. This is in preparation of an automated way to create Maya shading nodes directly from OSL shaders. This string has no effect in Katana.

    3Delight Material is being deprecated and replaced by 3Delight Principled. The later provides all the functionality provided by 3Delight Material, plus the ability to render metals, with less parameters and better usability (such as better parameter ranges, better naming, and better UI).

    The 3Delight Material is still part of the package for backward compatibility.
