I thought it was like that - however, still, I think it would be more fitting to have a levitating effect more than a creative flight effect ^^"
But creative flight is more fun ;D The main reason I did not implement levitating because I don't really want to replace anything already in thaumcraft.
I wouldn't fix that rendering bug on the matrix too fast lol, unless it causes performance problems, It looks kinda cool.
Its already been fixed.
