Mouse Wheel Grow/Shrink Selection
This script will allows you to use the mouse wheel to grow and shrink verts/edges/faces selection on Editable Poly and Edit_Poly objects.
Usage:
Assign it to a keyboard shortcut or button. After pressing the keyboard key/button, use the mouse wheel to grow or shrink the selection. While the tool is active you can pan, rotate and zoom(Ctrl+Alt+MMB) object in viewport and continue to add new verts/edges/faces to selection. Click on viewport with LMB or RMB to stop the tool.

Max 2020.3
Damn, too bad it doesn't work in max 2020.3.
When i press shortcut to invoke the tool, my gizmo turns off, which means that the tool is active, but scrolling just zooms the viewport. I tried all key combinations.

The installer is fixed and now the script works in 3ds Max 2020.
