I have the same question. Do I need to rewrite the plugin code for this? Is there any other solution? To be like in the SRD_CameraCore plugin, in which the zoom effect is instantaneous.
The plugin is wonderful, but the settings are not enough...
Looks like I have a solution.
If the default zoom is 1.6
then to instantly reset the zoom to 1.0 on a certain map, you need to set the following settings
MapZoom set 0.625 0.625 duration 1
(i.e. 1/1.6=0.625 for x and y).
It seems to take longer to think while loading but it works.
