hello Alexander, I really loved your these draw works. I loved cathedrals too.I started 3ds Max new. And I really really want to meet you, if you wanna to do. By the way, my name is Duacan, from Turkey. also Im working for learning and speaking German. Cause Deutschland is the my first country for living. Whatever, take care yourself, Tschüss. insta: 06optimusprime06

nice blog but here is the thing, what is wrong with overlaping uv's and mirroring them, what are the cons of overlapping them and why is this method better in the case of uv? thanks

Thank you @Fcardoso The volumetric light is available in the latest 2018.3 beta. In the visual environment setting, there is a new option to select Volumetric light fog. The screen I shared is from 2018.2 during that time I was using a script to enable it :)

Arnold 5.2 Released
13 August, 2018

Solid Angle has revealed Arnold 5.2 that adds a number of new features in addition to performance and usability improvements. The new release, for example, brings improved shaders with the addition of a new Cell Noise, but there’s more. Let’s study the update. 

  • Texture baking: A new type of node called uv_camera has been added that will produce an image of a given polymesh’s shaded UV space as output, which can be useful for texture baking. (#6091, #7206)
  • Improved sampling of spherical lights: A new technique for sampling point lights has been added which can show significant reductions in noise, especially for large lights illuminating surfaces at grazing angles (rim lighting, for example). (#5534)
  • Faster adaptive subdivision: Adaptive subdivision is now up to 2x to 3x faster even on a single thread. In addition, the adaptive codepath has been multi-threaded to fully take advantage of machines with many cores. The aggregated speedup in such machines can be 15x or more. (#2311, #7186, #7201, #7229)
  • Improved EXR read performance: Threaded read performance and scaling of OpenEXR files has been greatly improved. (#6605)
  • noice denoiser improvements: The stability and usability of the high-quality noice denoiser has been improved thanks to various bugfixes and improved error checking. In particular, the original metadata, display windows, bitdepth and compression are preserved in output files. (#7226)
  • OptiX denoiser improvements: The GPU memory consumption of the fast OptiX denoiser has been greatly reduced proportionally to the number of denoised AOVs. Fringing artifacts around HDR pixels have been reduced. (#6885, #7100, #7190, #7333, #6880)
  • Sheen in standard_surface: The standard_surface shader supports a new, energy-preserving sheen effect designed to render cloth-like microfiber materials such as velvet. The sheen effect is layered on top of the diffuse and subsurface components. (#7234)
  • New cell_noise shader: A new cell_noise shader has been added which can create many different useful cell-like patterns. The color of each cell is mapped to a palette parameter, enabling the easy creation of patterns with colors chosen from a specific palette. (#5985, #6051)
  • New controls in range shader: The range shader has been augmented with parameters to control contrast, bias and gain. (#7277)
  • RGB clamping in clamp shader: The clamp shader can now be configured to either a scalar or color mode. (#7278)
  • Matrix shaders: The matrix_multiply_vector and matrix_transform shaders have been reinstated. (#7243)
  • Built-in Cryptomatte: Cryptomatte AOV shaders and filters are now being included as a part of the Arnold core package. (#7301)
  • New built-in volume AOVs: The Z depth for the first volume contribution can now be output in a flat AOV with volume_Z (depth AOV for volumes was already available in deep files). Also, ID now works for volumes. (#7326, #7327)
  • New control in toon shader: Edge detection can now be controlled using a STRING type user data called toon_id. This feature is enabled when user_id is checked. Otherwise, the detected edges will be driven by the object’s own name as a toon-specific ID. (#7125)
  • Alembic procedural improvements: The Alembic library has been updated to 1.7.5 in this release. User data parameters that clash with shape parameters will now get an underscore prefix instead of a warning. Added an object_transform parameter to allow additional transformations on the generated geometry. Added a make_instance parameter so that the Alembic procedural will automatically create instances of objects present in multiple Alembic procedurals (experimental; disabled by default) (#6916, #6947, #7076, #7109, #7163, #7242, #7261, #7286)
  • Improved operator assignments: Assignment expressions in operators have improved functionality with regards to reference and string types. (#7284, #7287)
  • Upgrade to OSL 1.9.9: This upgraded version of OSL addresses several reported limitations involving locales, the availability of certain noise types, and compatibility issues with utility functions like transformc being promoted to built-in function definitions. (#6225)
  • Updated to RLM 12.4BL2: The RLM license server and library have been upgraded from version 12.2BL2 to 12.4BL2, which fixes sporadic access violations and hangs. (#7350, #7120)
