You can read this message on pastebin as well since all my formatting got stripped. http://pastebin.com/HG7fdrda So, I’ve been mucking about with particle hair and hair dynamics and whatnot.These are the steps I took prior to blender crashing.Create particle hair, set strands to 10, emit from faces with random and even distribution checked as well as random instead of jittered and turn on dynamicsset Segments to 50 and enable advanced.under dynamics:set stiffness to 0.001set steps to 10under velocityset normal to 2 and tangent to 0.05under display:set steps to 7under renderset strand render to true, b-spline to true and set steps to 9under childrenset children to interpolatedset display to 1 and render to 20set seed to 8set clump to 0.292 and shape to 0.356set size to 0.010 and endpoint to 0.080set shape to 0.220set the second size value to 1.0set kink to nothingsimulate up to frame 148saverenderchange particle count to 50 instead of 10savetry to go back to frame 1crashreloadcrashreloadcrashload blend2it works.Crash log:# Blender 2.69 (sub 0), Revision: 60991# backtrace./blender() [0xf84687]./blender() [0xf848c5]/lib/x86_64-linux-gnu/libc.so.6(+0x35250) [0x7f5d266d4250]./blender(MEM_freeN+0x23) [0x1b3c013]./blender(modifier_setError+0xcd) [0x1547c1d]./blender() [0x14e074b]./blender(BKE_ptcache_read+0x366) [0x14e23b6]./blender(clothModifier_do+0x1dd) [0x151a79d]./blender(particle_system_update+0x15fe) [0x1545d8e]./blender() [0x1191857]./blender() [0x15c188a]./blender() [0x15c242a]./blender(BKE_object_handle_update_ex+0x56b) [0x14d616b]./blender() [0x14c2e07]./blender(BKE_scene_update_tagged+0x6b) [0x14c308b]./blender(wm_event_do_notifiers+0x484) [0xf9e474]./blender(WM_main+0x20) [0xf8bbc0]./blender(main+0x36d) [0xf86c79]/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f5d266c0995]./blender() [0xec38d5]Excuse the poor formatting, blenderartists seems to strip my posts of newlines (which can evidently be seen on every last one of my posts)
