I saw this on What Is New in Krakatoa MX 2.3.x0
Support for Thinking Particles 5.x and 6.0, as well as future TP versions via an Expert Mode accessible via MAXScript.
Any details?
Sure.
In the current build of Krakatoa MX 2.3.1, you can use 5.0 and 6.0 out of the box.
For 6.1 and 6.2, you need to manually enable the TP Expert Mode for each session.
The UI way of enabling it is:
*Open the Krakatoa GUI
*Open the Preferences dialog by clicking on the button at the bottom of the Main Controls rollout
(alternatively, use the Krakatoa menu > “Open the Krakatoa Preferences dialog” menu item).
*Expand the System Preferences rollout.
*Click the “Press to Enable TP Expert Mode. If you are unsure what this does, Don’t Press It!” button 
The drawback of this approach is that each time you restart Max, you have to do this again as it is not a switch, it is a function call that enables the special mode.
In order to enable the 6.x support permanently in 2.3.1, you can use MAXScript to call the function on startup.
For example, you could go to your StartupScripts folder - run the following in the MAXScript Listener to find where it is:
shellLaunch (GetDir #startupscripts) ""Then create a new KMX_TP6x.MS file in that folder and enter the following in it:
FranticParticles.EnableTPExpertMode()Save the file, restart Max.
As the startup script will be run when Max launches, Krakatoa’s TP 6.x expert mode should now be engaged automatically.
For the upcoming KMX update (around the time 3ds Max 2016 ships), the 6.x support will be enabled by default and the above workaround will not be necessary anymore. We already support TP 6.x in other products like Frost MX.
Worked well.
Thanks!
