Camera Range Viewer
I've released the first version of my 'Camera Range Modifier' for 3dsmax.
It took a while for me to release it since I had many approaches on how to make this.
The way I've done it now (by drawing directly in the graphics viewport) is by far the best way to do this.
I initially tried by creating plane objects and so on, but this was not a smart way to do it.
I have a to do list, which has these items:
1) Custom color for the planes.
2) Better support for Nitrous modes.
3) Texture map support
4) Transparent plane.
