[Bf-committers] Blender developers IRC meeting minutes, 3 july 2011

[Bassam Kurdali]

+1 
my understanding:

short term:
add new particle system next to old one *
*rename old one 'hair' and remove non hair types from it?
*convert old .blend particles to new system, but leave hair emitters
alone?

long term:
improvement / rewrite of hair as a thing different from particles.

which would get the new system into blender fast, and not cause
regressions.
