particle options, disapears when using a disk cashe

When i enable to use a particle disk cache in blender 2.7
i loose the following sub property panel menu items:

  • velocity options
  • rotation
  • physics

Also i have installed molecular script, as i need the particles to behave like sand.
But the disappearing of above menu items happen before i do anything with the molecular add on.

I dont know if there where changes in blender 2.7 maybe particles behave different now ?
So that i have to look elsewhere to set those things elsewhere now.
If anyone could enlight me on this one, it would be great.

Enabling the ‘Disk Cache’ tickbox does not remove those options for me.

If you enable ‘External’ they will disappear since you are reading the particle settings that are in the external cache file
