Wow, another bug! After i create a NEW ACTION with a VECTOR LAYER that doesn't bind to any bones.
after setup a simple loop by moving points here & there, when i hit PLAY button, nothing happen!!!
BUT the point motion playing just fine if i drag the slidebar on timeline!
WOW! serious bug!
Er sorry Hayasidist i didn't check this topic regularly, i thought that no one will answer. Actually it's not a Bug, it happened because i change Display Quality to Low haha
