Here’s an addon that creates a light aligned to the current view. It creates a toolshelf panel in the 3d view with a number of different options.
If you want to follow development,
The Github Project page
The tool is run by a button in the tool shelf. It is possible to use a custom keyboard shortcut, but it’s not working quite right at the moment so it’s disabled. You can select to either generate a lamp light or a mesh light. You can also just create a camera from view with no light.
The Panel has all the general options available for each light type and emission color and strength settings. With a mesh light object selected, you will also see the Ray Visibility options. These options only work for the creation of the object, and not for objects already created.
All objects created are also added to a group called “Light Cannon”. Keep in mind, some of the lamps are not visible when created because they’re out of view slightly. Change your view position and you’ll see them.
Any feedback and/or bug reports would be appreciated!
This was inspired by a post I saw on Lesterbanks about this post, a simple script for Maya to do the same.
Script updated to work with Blender 2.80. If you need the 2.7 version just check the github previous commit.
