Thanks flyinverted and Gilrock,
There is a total of 7 universes in the setup also.
Something has to be a bug in my program, just cant be that size given how small it is.
I'm going to build from scratch a new setup and sequence to see what happens.
again, thanks
UPDATE: FIXED
Removed effects from layers one at a time and saved. no change still large "fseq"
Installed media no fix.
Removed media no fix.
I completely rebuilt a new setup, model and sequence without media (animation only) and Bingo "fseq" size is now 50x smaller?
I think the Bug had to be a glitch in the model. Although the model is the same as used in two different sequences with media.
