i ran into an odd problem i cannot solve.
i have a scene with several objects. one is a head. as soon as i go into edit mode of one of the other objects, even a simple plane, click a vertex and move it, release the click then all the sudden the head (a multires obj) vanishes and the final render starts in the uv-image editor. after the render the viewport updates, the head is visible back again. but when i want move again a vertex the head vanishes and the render starts again… very annoying. blender says in the info line that it needs 1 gig ram, and when rendering it is about 6 gig ram.
this odd behaviour all the sudden started, after i had broke off a final render. how can i rescue the file? (i cannot put the blend here, it is massive…) please help.
this happens with blender 2.70 and 2.71. my specs are imac, macos 10.8.5, 32 gig ram, 2 gig on nvidiacard.
