GUI max particlefx count (SOLVED)

Max Particlefx Count
The max number of concurrent emitters, 64 by default.

Is this value actually allowed to be higher? Can the absolute max values things like this have be published somewhere?

What do you mean? If you increase the value you would be able to have more emitters.

There must have been something else going on (maybe another issue I reported recently) I tested in a stand alone project and increasing the amount worked.
