So Blender started crashing whenever I bake fluid for no reason (I mean no reason, discussion here). I'm thinking maybe reducing the amount of RAM it uses could help, but I can't figure out how to reduce it.

  • $\begingroup$ First you should find if memory limits are the cause before asking this question. $\endgroup$ – ideasman42 Jun 4 '16 at 1:02
  • $\begingroup$ @ideasman42 I'm almost certain they are because in Task Manager blender uses like 6GB of RAM then it crashes once there isn't any left. $\endgroup$ – Josh Silveous Jun 4 '16 at 1:04
  • $\begingroup$ Could you run Blender from a terminal and see what output you get? - blender.org/manual/render/workflows/command_line.html Typically errors are printed before crashing. $\endgroup$ – ideasman42 Jun 4 '16 at 1:05
  • $\begingroup$ @ideasman42 Already tried it, but no errors show up because blender doesn't just crash, my whole computer does and I have to restart. $\endgroup$ – Josh Silveous Jun 4 '16 at 1:07
  • $\begingroup$ do have swap enabled ? it's very slow but can help when there isn't enough space in RAM. $\endgroup$ – user2816 Jun 4 '16 at 1:09

File > User Preferences > System > Middle Column at the Bottom (Sequencer / Clip Editor:) and reduce the Memory Cache Limit: value (I believe it's in Kb, but you would have to check that).

    $\begingroup$ Already tried, apparently that only limits RAM for the sequence and clip editors, my problem is baking fluid $\endgroup$ – Josh Silveous Jun 4 '16 at 1:15
