HDRI Haven Presets
We have selected a range of useful interior and exterior HDRI maps from the HDRI Haven web site. These HDRI maps are available to anyone for free due to their generous CC0 license. For your convenience we have created a Preset Pack adding these HDRI maps to HDR Light Studio. These are provided at a resolution of 2,048 pixels wide. You can download higher resolutions if required from HDRI Haven. This Preset Pack can be downloaded by customers from your account at

Faster Applications Startup
The first time HDR Light Studio Tungsten Drop 3 runs, it will build a cache of thumbnail images on disc for the installed Presets. Thereafter, HDR Light Studio Presets are available to see immediately after application start up.

Float HDR Light Studio UI Panels
Use the new 'undock icon' whilst pressing the Control Key (Command on MacOS) to undock and float a user interface panel in HDR Light Studio. You can then move this UI panel over the top of the HDR Light Studio interface without it snapping back into the interface. Double click the top bar of the floating UI panel to return it to dock in the interface.

Support has been added for R21 - Updated documentation here.

Bug Fixes:
HDR Light Studio internal Render View: Fixed a bug where we did not handle Alembic hierarchies correctly, resulting in partially loaded scenes.
C4D: Redshift - Area Light width and height controls incorrectly swapped over.
C4D: Redshift - Production Rendering was turning off shadows from the environment lighting.
