Torch
Torch is a blender add-on that makes it easier to control lights
Demo:
When you create or select one or more lights, a dedicated icon will be displayed on the 3d view area. The created light always has an icon at the bottom left of the screen, making it easy to turn it on and off and adjust it.
You can change the position of the light according to the model, so it is easy to operate intuitively. To adjust the distance of the light to the surface press the CTRL key and dragging the gizmo left or right. For now Torch support normal mode and reflection mode, to switch between this mode press SHIFT key while dragging the gizmo, you can also flip the direction by holding ALT key.
You can also change the intensity, color, type and other registered properties on the torch UI on the 3D view.
Hope you enjoy using this tool!.
