Dealing with an animation you often have to make changes in some small time range. While in Maya and MoBu a time slider is double-function and you can easily switch over from a general scene time to a zoom time range and back, you don’t have such a chance in 3Dsmax.
I’ve made my mind to sort this disadvantage out and I’m presenting quite a simple macroscript. With its help you’ll be able to swith over between periods of a scene time.
How to use
Download script, run it and assign a convenient short cut (I’ve used Ctrl + Space).
By the first application of this short cut, the script “memorizes” a current period of a scene time. Then, after the next activation of the script there will be the following exchange: the current time range will be saved and its place will be taken up by previously saved one. In other words, the script swaps two time ranges: the current time range and the saved one.
