If we try to call the "FranticParticleRenderMXS.loadPresetAll " we get a system exception. It is no problem to call "FranticParticleRenderMXS.savePresetAll "
Fixed. It is mostly Autodesk’s fault (I have complained about the particular problem before, but they never fixed it).
I am not sure why it wasn’t affecting the UI call, but anyway, I was able to work around it and now it will load the preset when called from MAXScript.
