I use Show DEM tool as a way to take the color out of the AR sandbox projection and talk about black and white topographic maps. I’m wondering if there is a way to assign this to a hotkey. The issue with Show DEM is that once I assign it, it asks me to open a file – I literally just exit that prompt and then it works to switch to black and white. There may be a more efficient way to program this function.

In addition, I’m wondering how to code “pause topography”

Thanks all – this forum has been very helpful so far!

We switch between full-color and white maps for the same reason, using the control pipe. This Switch texture water to lava post describes how to change colors. For white, create a .cpt file with the following values.

-25.00 255 255 255
25.0 255 255 255

AFAICT, “Pause Topography” is not available for assignment to a key via the configuration files, but I could be wrong. If you are comfortable patching C++ source, the following diff will add a “pauseUpdates” control pipe command. This will toggle screen updates using the same algortihm the assigned key uses.

Sorry, the patch I posted has a mistake. (The dangers of hand-editing a patch.) The following should cleanly apply.
