Worked: (optional)

after setting a particle system on an object with tweaking some settings Blender 2.8 crashes

  • selecting an object with 2000 faces
  • adding a particle system
  • switch to hair settings
  • Emision settings: changing the length of the hair
  • Emision settings: typing a new number in the number field
  • Enter
  • crash

another case:

Based on the default startup or an attached .blend file (as simple as possible).

I just updated Blender.
I have the same problems.
Changing Properties or switching to Particle Edit are crashing Blender.

  • Emission: I can change Seed, Hair Length an Segments, but not Numbers
  • Not possible to get in Psrticle Edit Mode

I tested a few values and it seem that it only crashes on the Emission:Number Value of 0 - also in advanced mode

Can't get into Particle Edit mode


  • default cube
  • add particle system
  • while in Emitter Mode: emitter i do can go in particle edit mode
  • while in particle edit mode switching to Emitter Mode: hair
  • crash

Same here. Latest beta 2/15.
