presampling displacement, unloading geometry

[fareen]

can someone please tell me what it means when the current task in the render dialog says presampling displacement and unloading geometry in between the prepass cal.I dont have any vry displacement in my scene either and this crashes max when i am rendering a large res image, i also tried frame buffer also region renders

If u dont want to render any displacement then just uncheck Displacement in Global Switches, but i think u do have some dislpacement in your scene. May be any displacement map in materials?
