We have an artist working on an large environment scene who asked why the Camera speed gadget in the editor only goes to 8… I suggested they might like it to go to 11.
In looking at the code I see that MaxCameraSpeeds is hard-coded to (8) in EditorViewportClient.cpp.
It would be very nice if the number of speeds and values were configurable via INI file.
In addition to camera speed slider you can increase the speed above 8 by holding right mouse button + scroll up.
We just discovered that holding the mouse-wheel button and up/down on the wheel appears to modify and internal hidden speed multiplier which is separate from the Camera speed in the range of 1/10th to 10x.
This satisfies our need to reach higher and lower speeds.
