Not sure why this has never been implemented before in a 3D program, but looks pretty straight forward. It would be great to be able to look at a mesh and say, "I want a bright highlight to appear right here." So you move the mouse to that spot, right-click "Reflection Vector", and Octane calculates the ray that would travel from your eye through the picture plane, and bounce off the mesh at that point into the scene space. It would display the ray so that you could snap a light source to it anywhere along its length. This should ensure that you get the reflected highlight exactly where you want it without a lot of wasted time with trial & error.

Oh I forgot about HDR Light Studio! Neber got a chance to play with it.
Sure would be nice if a reflection vector could get be native on Octane. Would simplify placement of light sources A LOT.
