Some time ago I see this tutorial http://users.utu.fi/jhkarh/prog/particles/edit_teaser.swf. But the problem is that I don’t know where I can find a Blender version with the “particle edit properties”. Somebody knows where I can find it??
graphicall.org has a bunch of svn blender builds, optimized builds, etc.
Graphicall.org is the place to check for experimental builds.
