Re: [TCML] GU5B VTTC

Teslina,

Yes, you have excellent results now with the staccato and more power.
A big question in VTTC work is exactly what factors contribute to
sword sparks vs. branched sparks.  I noticed your sparks occasionally
form the single sword spark.  Usually there's some branching in your 
sparks
in this video.  Both ways are nice effects.  I know some of the
factors that produce this branching, but not all.  Research continues.

Cheers,
John
