Particles won't activate

[JohnnyRandom]

It works for me as far as I can see the particle ticks in the viewport. You can try just cycle the emission state with <PF_Source>.Enable_Particles

In the Position Object operator you need to enable If Location Is Invalid->Delete Particles


Position_Object : Helper <Position_Object>.delete Integer default:0

When set to true, if the software cannot place a particle according to the current option, it deletes the particle. When set to false, particle placement is undefined; that is, it depends on other variables.



Hope that helps :)

The .delete parameter worked like a charm, thanks John!

I tried toggling the .enable_particles parameter but with no success. It should be true by default too.
Tried the script in max 2008 and 2010 and the particles still won't show up before I create a new system and delete it. I.e if I create a new event in the script like this:

particleFlow.BeginEdit()
local lolEvent = event()
particleFlow.EndEdit()

If run the script and delete this event manually, the particles show up. If I try to delete the event using the script, the particles don't show up.
I must be missing something.

There is a known bug somewhere deep in PFlow which prevents a newly script-created system from generating particles unless the scene is saved and then reloaded again.

The hack I have been using since Max 6 is to call holdMaxFile() followed by (fetchMaxFile quiet:true) to enforce an update. It is true that it can take a bit of time depending on the content, but it tends to solve the issue with newly created flows using MAXScript.
