What's New in HDR Light Studio 8 - Drop 1?

Product naming
We are now naming HDR Light Studio by the release numbers again - not nick names like Carbon, Tungsten, and Xenon. The product name was getting too long and a bit confusing for new customers.
This is HDR Light Studio version 8, drop 1 - so it's called 8.1.0

User Interface Enhancements

LightPaint Expanded
More lighting control directly inside the Render Views and Canvas
The user interface in the Render Views and Canvas have been improved to allow mouse input to control key lighting settings like - scale, rotation, brightness, and more. Keyboard shortcuts keys can be used to switch the mode. This means you can do more directly inside the views without needing to use sliders in the Light Properties panel. This provides a far faster workflow.

Light Properties split into 2 tabs - Settings & Appearance
There are a lot of settings in the Light Properties panel. Users were spending too much time scrolling up and down a long list of settings. We fixed this by splitting the properties into 2 tabbed sections. Read more

New Light Content Types

Scrim Light
The Scrim Light mimics how a photographer would light in the studio (see image below) when shining a light source at the back of a sheet of material. The Scrim Light in HDR Light Studio produces a very realistic light that is easy to adjust in a physical way. Most of the settings for this light can be controlled by dragging in 2D views of the light setup. This is far faster and more intuitive than using lots of sliders. The Scrim Light is the most advanced and controllable procedural light available in HDR Light Studio - and can produces a huge range of realistic lighting effects.

CTRL + Drag/Drop Presets, forces Area Light creation
When making a new light from a Preset with 3D mapping - holding the CTRL key will force the creation of an Area Light.

Improved handling of Preset texture files
When opening a HDR Light Studio project file created on a different computer, HDR Light Studio will now automatically try to locate preset textures files in your own Presets installation. This will avoid the user needing to manually fix missing file links when moving HDR Light Studio projects between computers.

HDR Light Studio - Bug Fixes

Motion blur got broken a few releases ago by a code change in another area of HDR Light Studio. Motion blur now works correctly.

We now support on/off/solo/pickable from edit menu in the undo stack.

Canvas would not update when nudging lights via keyboard shortcuts - this is fixed.

HDR Light Studio should now start up faster. It has been optimized.

Additive Blend on Value channel was incorrectly setting the alpha on production renders - this is fixed.

Correct OCIO handling when OCIO env var/application settings are used. Fallback to default also works correctly now too.
